Therapeutic Options for Migraines in the Microsurgical Patient: A Scoping Review

BACKGROUND

There exists an increasing array of treatments proposed to prevent, alleviate, and abort symptoms of a migraine; however, for patients who undergo reconstructive microsurgery, caution must be taken to preserve vascular integrity. This study is the first-to-date scoping review of vascular and bleeding risk of current migraine therapies, with the purpose of identifying potential therapeutic agents for postoperative migraine management appropriate for microsurgical patients.

METHODS

Currently available migraine therapeutics were compiled from the UpToDate software system and the American Academy of Family Physicians. A PubMed literature review was performed for each therapeutic's effect on bleeding or vascular involvement. Data were compiled into tables of abortive, symptom-controlling and prophylactic, and nonpharmacologic treatments. Expert microsurgeons reviewed the data to provide recommendations for optimized patient care.

RESULTS

Triptans and other ergot derivatives demonstrated strong evidence of vasoconstriction and were greatly advised against for immediate postmicrosurgical use. Novel pharmaceutical therapies such as lasmiditan and calcitonin gene-related peptide antagonists have no literature indicating potential for vasoconstriction or hematoma and remain an investigational option for abortive medical treatment. For symptom control, acetaminophen appears the safest option, with clinical judgment and further research needed for use of nonsteroidal antiinflammatory drugs. Alternative treatment techniques may include migraine prophylaxis with botulinum toxin injection or nutraceutical treatment by means of magnesium supplementation or coenzyme Q10 administration, minimizing the need for additional medication in the postoperative setting.

CONCLUSIONS

Patients undergoing reconstructive microsurgery have a unique medical profile limiting the therapeutic options available to treat migraines. This review provides preliminary evidence to be considered as a guide for prescribing therapeutics for migraine in the postoperative setting.

Post-prostatectomy incontinence: a guideline of guidelines

AIM

To provide a comprehensive review of guidelines from various professional organisations on the work-up and management of post-prostatectomy Incontinence (PPI).

MATERIALS AND METHODS

The following guidelines were included in this review: European Association of Urology (EAU 2023), American Urological Association/Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction (AUA/SUFU 2019), International Consultation on Incontinence (ICI, 2018), the Canadian Urological Association (CUA, 2012) and the Urological Society of India (USI, 2018).

RESULTS

In general, the guidelines concur regarding the significance of conducting a comprehensive history and physical examination for patients with post-prostatectomy incontinence (PPI). However, there are variations among the guidelines concerning the recommended additional investigations. In cases of troublesome PPI, male slings are typically recommended for mild to moderate urinary incontinence (UI), while artificial urinary sphincters are preferred for moderate to severe UI, although the precise definition of this severity remains unclear. The guidelines provided by AUA/SUFU and the ICI have offered suggestions for managing complications or persistent/recurrent UI post-surgery, though some differences can be observed within these recommendations as well.

CONCLUSION

This is a first of its kind review encompassing Guidelines on PPI spanning over a decade. Although guidelines share overarching principles, nuanced variations persist, posing challenges for clinicians. This compilation consolidates and highlights both the similarities and differences among guidelines, providing a comprehensive overview of PPI diagnosis and management for practitioners. It is our expectation that as more evidence emerges in this and other areas of PPI management, the guidelines will converge and address crucial patient-centric aspects.

Treatment of Postoperative Neck Dissection Cervical Lymphocele With Percutaneous Bleomycin Sclerotherapy

Lymphatic leak after lymph node dissection is a rare but well-known surgical complication that is often treated with conservative management and ultimately reoperation. The purpose of this report is to offer an alternative treatment for chyle leak that avoids hospitalization and subsequent surgery. Sclerotherapy has been used to treat lymphatic leaks in the past and has been shown to be safe and effective. This report presents a patient with a known cervical lymphocele who was followed through multiple sclerotherapy appointments until resolution of the lymphocele.

The effect of physical therapy and mechanical stimulation on dysfunction of lower extremities after total pelvic exenteration in cervical carcinoma patient with rectovesicovaginal fistula induced by radiotherapy: a case report

BACKGROUND

Total pelvic exenteration is the ultimate solution for rectovesicovaginal fistula caused by radiation therapy, yet total pelvic exenteration frequently causes intraoperative complications and postoperative complications. These complications are responsible for the dysfunction of lower extremities, impaired quality of life, and even the high long-term morbidity rate, thus multidisciplinary cooperation and early intervention for prevention of complications are necessary. Physical therapy was found to reduce the postoperative complications and promote rehabilitation, yet the effect on how physiotherapy prevents and treats complications after total pelvic exenteration and pelvic lymphadenectomy remains unclear.

CASE PRESENTATION

A 50-year-old Chinese woman gradually developed perianal and pelvic floor pain and discomfort, right lower limb numbness, and involuntary vaginal discharge owing to recurrence and metastasis of cervical cancer more than half a year ago. Diagnosed as rectovesicovaginal fistula caused by radiation, she received total pelvic exenteration and subsequently developed severe lower limb edema, swelling pain, obturator nerve injury, and motor dysfunction. The patient was referred to a physiotherapist who performed rehabilitation evaluation and found edema in both lower extremities, right inguinal region pain (numeric pain rate scale 5/10), decreased temperature sensation and light touch in the medial thigh of the right lower limb, decreased right hip adductor muscle strength (manual muscle test 1/5) and right hip flexor muscle strength (manual muscle test 1/5), inability actively to adduct and flex the right hip with knee extension, low de Morton mobility Index score (0/100), and low Modified Barthel Index score (35/100). Routine physiotherapy was performed in 2 weeks, including therapeutic exercises, mechanical stimulation and electrical stimulation as well as manual therapy. The outcomes showed that physiotherapy significantly reduced lower limb pain and swelling, and improved hip range of motion, motor function, and activities of daily living, but still did not prevent thrombosis.

CONCLUSION

Standardized physical therapy demonstrates the effect on postoperative complications after total pelvic exenteration and pelvic lymphadenectomy. This supports the necessity of multidisciplinary cooperation and early physiotherapy intervention. Further research is needed to determine the causes of thrombosis after standardized intervention, and more randomized controlled trials are needed to investigate the efficacy of physical therapy after total pelvic exenteration.

Effect of transcutaneous electrical acupoint stimulation on postoperative urinary function in elderly patients undergoing total hip arthroplasty

OBJECTIVES

To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative urinary function in elderly patients undergoing total hip arthroplasty (THA).

METHODS

One hundred and eighty elderly patients undergoing unilateral THA without indwelling urinary catheters were randomly assigned to a TEAS group (90 cases, 3 cases dropped out, 4 cases were eliminated) and a sham TEAS group (90 cases, 1 case dropped out, 4 cases were eliminated). Both groups received fascia iliac block and subarachnoid block anesthesia under ultrasound guidance. The patients in the TEAS group were treated with TEAS at Zhongji (CV 3), Guanyuan (CV 4), and bilateral Huiyang (BL 35), Ciliao (BL 32) 30 minutes before anesthesia initiation, with dissperse-dense wave, frequency of 2 Hz/100 Hz, until 30 minutes after surgery. The patients in the sham TEAS group underwent the same procedure with the device applied at the same acupoints but without electrical stimulation. The incidence of postoperative urinary retention (POUR), time to first void, voiding threshold, urinary adenosine triphosphate (ATP) level, postoperative abnormal voiding status (bladder residual volume, re-catheterization rate, nocturia occurrence), and postoperative incidence of urinary tract infection (UTI) and prosthetic joint infection (PJI) were observed in both groups.

RESULTS

The incidence of POUR in the TEAS group was lower than that in the sham TEAS group (P<0.05); the time to first void in the TEAS group was shorter than that in the sham TEAS group (P<0.05); the voiding threshold in the TEAS group was lower than that in the sham TEAS group (P<0.05); the urinary ATP level in the TEAS group was higher than that in the sham TEAS group (P<0.05); the bladder residual volume in the TEAS group was lower than that in the sham TEAS group (P<0.05); the nocturia occurrence in the TEAS group was lower than that in the sham TEAS group (P<0.05). However, there was no statistically significant difference in re-catheterization rate, incidence of UTI, and incidence of PJI between the two groups (P>0.05).

CONCLUSIONS

TEAS could effectively reduce the occurrence of postoperative urinary retention and improve the postoperative urinary function in elderly patients undergoing THA, which might be related with increasing the urinary ATP level.

Intermittent Self-catheterization for Bladder Dysfunction After Deep Endometriosis Surgery: Duration and Factors that Might Affect the Recovery Process

STUDY OBJECTIVE

To assess the duration needed for regaining normal bladder voiding function in patients with postoperative bladder dysfunction requiring intermittent self-catheterization after deep endometriosis surgery and identify risk factors that might affect the recovery process.

DESIGN

Retrospective study based on data recorded in a large prospective database.

SETTING

Endometriosis referral center.

PATIENTS

From September 2018 to June 2022, 1900 patients underwent excision of deep endometriosis in our center; 61 patients were discharged with recommendation for intermittent self-catheterization and were thus included in the study.

INTERVENTIONS

Intermittent self-catheterization after endometriosis surgery.

MEASUREMENTS AND MAIN RESULTS

A total of 43 patients (70.5%) stopped self-catheterization during the follow-up period. Median follow-up was 25 weeks (range, 7-223 wk). Surgery was performed laparoscopically in 48 patients (78.7%) and robotically in 13 (21.3%); 47 patients (77%) had nodules involving the digestive tract, 11 (18%) had urinary tract involvement, 29 had parametrial nodules (47.5%), and 13 (21.3%) had sacral plexus involvement. The probability of bladder voiding function recovery and arrest of self-catheterization was 24.5%, 54%, 59%, 72%, and 77% at 4, 8, 12, 52, and 78 weeks, respectively. Cox's multivariate model identified preoperative bladder dysfunction as the only statistically significant independent predictor for arrest of self-catheterization (hazard ratio, 0.36; 95% confidence interval, 0.15-0.83).

CONCLUSION

Patients requiring intermittent self-catheterization for bladder dysfunction after deep endometriosis excision may spontaneously recover bladder function in 77% of cases. Symptoms suggesting preoperative bladder voiding dysfunction should be reviewed before planning surgery, and patients should be informed of the higher postoperative risk of long-term bladder voiding dysfunction.

Electroacupuncture alleviates intestinal inflammation via a distinct neuro-immune signal pathway in the treatment of postoperative ileus

BACKGROUND

The induction of intestinal inflammation as a result of abdominal surgery is an essential factor in postoperative ileus (POI) development. Electroacupuncture (EA) at ST36 has been demonstrated to relieve intestinal inflammation and restore gastrointestinal dysmotility in POI. This study aims to elucidate the neuroimmune pathway involved in the anti-inflammatory properties of EA in POI.

METHODS

After intestinal manipulation (IM) was performed to induce POI, intestinal inflammation and motility were assessed 24 h post-IM, by evaluating gastrointestinal transit (GIT), cytokines expression, and leukocyte infiltration. Experimental surgery, pharmacological intervention, and genetic knockout mice were used to elucidate the neuroimmune mechanisms of EA.

RESULTS

EA at ST36 significantly improved GIT and reduced the expression of pro-inflammatory cytokines and leukocyte infiltration in the intestinal muscularis following IM in mice. The anti-inflammatory effectiveness of EA treatment was abolished by sub-diaphragmatic vagotomy, whereas splenectomy did not hinder the anti-inflammatory benefits of EA treatment. The hexamethonium chloride (HEX) administration contributes to a notable reduction in the EA capacity to suppress inflammation and enhance motility dysfunction, and EA is ineffective in α7 nicotinic acetylcholine receptor (α7nAChR) knockout mice.

CONCLUSIONS

EA at ST36 prevents intestinal inflammation and dysmotility through a neural circuit that requires vagal innervation but is independent of the spleen. Further findings revealed that the process involves enteric neurons mediating the vagal signal and requires the presence of α7nAChR. These findings suggest that utilizing EA at ST36 may represent a possible therapeutic approach for POI and other immune-related gastrointestinal diseases.

Perioperative Blood Transfusion Is Associated with Worse 30-Day Mortality and Complications After Thoracic Endovascular Aortic Repair

BACKGROUND

It is not uncommon for patients requiring vascular surgery, and in particular aortic surgery, to have increased requirements for blood transfusion. However, studies examining the effects of perioperative transfusion for thoracic endovascular aortic repair (TEVAR) are limited. Using large multicenter data, we aimed to study the impact of perioperative blood transfusion on 30-day mortality and complications after TEVAR.

METHODS

A total of 9,263 patients who underwent TEVAR were included in this retrospective study from the multicenter Vascular Quality Initiative cohort spanning 2010-2022. We excluded patients who were post-traumatic, anemic (World Health Organization criteria: hemoglobin < 12 g/dl and < 13 g/dl for females and males respectively), who underwent open conversions or presented with ruptured aneurysms. Primary outcomes were 30-day mortality and stroke. Secondary outcomes were postop congestive heart failure (CHF), respiratory complications, spinal cord ischemia (SCI), myocardial infarction (MI) and any postop complications (composite variable). Poisson regression with robust variance was performed to determine the risk of post op outcomes comparing patients who received red blood cells (RBCs) to those who did not.

RESULTS

Comparing patients without any transfusion (n = 8,223), perioperative transfusion of 1-3 units (n = 735) was associated with 3-fold increased risk of 30-day mortality (adjusted relative risk [aRR] 3.30, 95% confidence interval [CI] 2.39,4.57, P < 0.001), almost 2-fold increased risk of stroke (aRR 1.98, 95% CI 1.24,3.15, P = 0.004), 2.7-fold increased risk of SCI (aRR 2.66, 95% CI 1.87-3.77, P < 0.001), 3-fold increased risk of MI (aRR 3.40, 95% CI 2.30, 5.03, P < 0.001), 2-fold increased risk of CHF (aRR 2.04, 95% CI 1.09, 3.83, P = 0.03), 3.5-fold increased risk of respiratory complications (aRR 3.49, 95% CI 2.67, 4.56, P < 0.001), and 2-fold increased risk of any postop complication (aRR 2.36, 95% CI 2.04, 2.73, P < 0.001). These effects were even higher in patients transfused 4 or more units (n = 305) than seen in the effects seen in those transfused 1-3 units; comparing each group to patients who received none.

CONCLUSIONS

In hemodynamically stable patients undergoing TEVAR for nonemergent/emergent and nontraumatic indications, transfusion of any amount perioperatively is associated with worse 30-day mortality, stroke, SCI, MI, CHF, and respiratory complications. A conservative transfusion approach and multidisciplinary care to identify complications and rescue TEVAR patients who receive any amount of RBCs perioperatively might help improve outcomes. Future studies to understand the mechanisms of outcomes for transfused patients are needed.

The role of traditional Chinese medicine in postoperative wound complications of gastric cancer

Due to the high risks of postoperative complications brought on by gastric cancer, traditional Chinese medicine (TCM) as a commonly used therapy, has exerted its vital role in postoperative recovery care. In this sense, this meta-analysis was conducted to explore the related documents about TCM's impact on gastric cancer postoperative recovery. During the research, we explored a total of 1549 results from databases PubMed, China National Knowledge Infrastructure (CNKI), Embase, Cochrane Library and Web of Science (WoS). Thirty-two clinical randomized trials (RCTs) were then selected and analysed for this meta-analysis by using the software RevMan 5.4 (under PRISMA 2020 regulations), with a population of 3178 patients. Data prove that TCM therapy reduced the risks for postoperative complications exposure by an estimated average of 19% (95% CI). Among the complications, TCM therapy suppressed the risks of wound infection and incisional infections by 53% and 48% respectively. Meanwhile, the patient's wound healing duration exhibited a significant reduction compared to those without TCM treatment, with a difference at around 0.74 days (95% CI). TCM also exerted its potential to strengthen the patient's immune and health conditions, leading to a significantly promoted gastrointestinal function in the patients with a shorter duration to release first exhaustion and defecation compared to those with no TCM therapy. In addition, similar promoted phenomena also exist in those patients with TCM therapy in terms of their immunity and nutritional conditions. These facts all indicate a positive impact of TCM therapy in clinical applications.

Anastomotic leaks and the relationship with anastomotic strictures after esophageal atresia surgery; effects of patient characteristics

BACKGROUND

This study aimed to evaluate the link between anastomotic leaks (AL) and anastomotic strictures (AS) after esophageal atresia surgery and the influence of patient demographics.

MATERIALS AND METHODS

The clinical data of neonates who underwent surgical repair for esophageal atresia were retrospectively reviewed. The results of AL treatment and the relationship with AS, also the effects of patient characteristics were examined with logistic regression analysis.

RESULTS

Primary repair was performed on 122 of 125 patients who underwent surgery for esophageal atresia. AL occurred in 25 patients and 21 were treated non-operatively. While 4 patients were re-operated, AL recurred in 3 and led to the death of one. There was no correlation between the development of AL and sex or the presence of additional anomalies. The gestational age and birth weight of patients with AL were significantly higher than those of patients without. AS developed in 45 patients. The mean gestational age was significantly higher in patients who developed AS (p < .001). While the development of AS was significantly higher in patients with AL (p = .001), the number of dilatation sessions needed was also significantly higher in these patients (p = .026). Complications related to anastomosis were less common in patients whose gestational age was ≤33 weeks.

CONCLUSION

Non-operative treatment remains effective for AL after esophageal atresia surgery. AL increases the risk of developing AS and significantly increases the number of dilatation sessions needed. Anastomotic complications are less common in patients with lower gestational age.NOVEL ASPECTSGestational age and birth weight were found to be significantly higher in patients with anastomotic leaks than in those without and fewer anastomotic complications were encountered in patients whose gestational age was ≤ 33 weeks.Anastomotic stricture development was significantly higher in patients with anastomotic leaks and the number of dilatation sessions needed for treatment was also significantly higher in these patients.

Sacral Neuromodulation in Patients With Low Anterior Resection Syndrome: The SANLARS Randomized Clinical Trial

BACKGROUND

Sacral neuromodulation might be effective to palliate low anterior resection syndrome after rectal cancer surgery, but robust evidence is not available.

OBJECTIVE

To assess the impact of sacral neuromodulation on low anterior resection syndrome symptoms as measured by validated scores and bowel diaries.

DESIGN

Randomized, double-blind, 2-phased, controlled, multicenter crossover trial (NCT02517853).

SETTINGS

Three tertiary hospitals.

PATIENTS

Patients with major low anterior resection syndrome 12 months after transit reconstruction after rectal resection who had failed conservative treatment.

INTERVENTIONS

Patients underwent an advanced test phase by stimulation for 3 weeks and received the pulse generator implant if a 50% reduction in low anterior resection syndrome score was achieved. These patients entered the randomized phase in which the generator was left active or inactive for 4 weeks. After a 2-week washout, the sequence was changed. After the crossover, all generators were left activated.

MAIN OUTCOME MEASURES

The primary outcome was low anterior resection syndrome score reduction. Secondary outcomes included continence and bowel symptoms.

RESULTS

After testing, 35 of 46 patients (78%) had a 50% or greater reduction in low anterior resection syndrome score. During the crossover phase, all patients showed a reduction in scores and improved symptoms, with better performance if the generator was active. At 6- and 12-month follow-up, the mean reduction in low anterior resection syndrome score was -6.2 (95% CI -8.97 to -3.43; p < 0.001) and -6.97 (95% CI -9.74 to -4.2; p < 0.001), with St. Mark's continence score -7.57 (95% CI -9.19 to -5.95, p < 0.001) and -8.29 (95% CI -9.91 to -6.66; p < 0.001). Urgency, bowel emptiness sensation, and clustering episodes decreased in association with quality-of-life improvement at 6- and 12-month follow-up.

LIMITATIONS

The decrease in low anterior resection syndrome score with neuromodulation was underestimated because of an unspecific measuring instrument. There was a possible carryover effect in sham stimulation sequence.

CONCLUSIONS

Neuromodulation provides symptoms and quality-of-life amelioration, supporting its use in low anterior resection syndrome. See Video Abstract .

Assessing the efficacy of Naoxintong capsules on wound healing in post-craniotomy patients: A clinical perspective

This study was conducted to determine whether Naoxintong capsules may enhance wound healing and reduce postoperative complications in individuals having craniotomies. A total of 120 patients at Tongji Hospital, Shanghai, participated in this clinical perspective study conducted from April 2022 to June 2023. Participants were divided into treatment group (n = 60), receiving standard care plus Naoxintong capsules and control group (n = 60), receiving standard care only. Primary outcomes included the rate of wound healing, while secondary outcomes encompassed postoperative complications and patient-reported outcomes on pain and quality of life. The treatment group exhibited significantly enhanced wound healing rate than the control at Day 7 (40.33 vs. 25.67%, p < 0.05), Day 14 (75.17 vs. 50.83%, p < 0.05) and Day 28 (94.83 vs. 79.50%, p < 0.05). Postoperative complications were markedly reduced in the treatment group, with lower rates of infection (p < 0.05), wound dehiscence (p < 0.05) and cerebrospinal fluid leakage (p < 0.05). Furthermore, patient-reported outcomes significantly favoured the treatment group, with reduced pain scores and improved quality of life at 4 weeks post-surgery(p < 0.05). Naoxintong capsules thus significantly enhanced the wound healing and reduced postoperative complications, contributing to improved patient-reported outcomes in post-craniotomy patients. These findings advocated for the integration of Naoxintong in postoperative care, highlighting the potential of traditional Chinese medicine in modern surgical recovery protocols. Further studies with larger cohorts are recommended to validate these findings and explore the underlying mechanisms.

Neonatal Chylothorax and Early Fluid Overload After Cardiac Surgery: Retrospective Analysis of the Neonatal and Pediatric Heart and Renal Outcomes Network Registry (2015-2018)

OBJECTIVES

To evaluate the association between postoperative cumulative fluid balance (FB) and development of chylothorax in neonates after cardiac surgery.

DESIGN

Multicenter, retrospective cohort identified within the Neonatal and Pediatric Heart and Renal Outcomes Network (NEPHRON) Registry.

SETTING

Twenty-two hospitals were involved with NEPHRON, from September 2015 to January 2018.

PATIENTS

Neonates (< 30 d old) undergoing index cardiac operation with or without cardiopulmonary bypass (CPB) entered into the NEPHRON Registry. Postoperative chylothorax was defined in the Pediatric Cardiac Critical Care Consortium as lymphatic fluid in the pleural space secondary to a leak from the thoracic duct or its branches.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Of the 2240 NEPHRON patients, 4% ( n = 89) were treated for chylothorax during postoperative day (POD) 2-21. Median (interquartile range [IQR]) time to diagnosis was 8 (IQR 6, 12) days. Of patients treated for chylothorax, 81 of 89 (91%) had CPB and 68 of 89 (76%) had Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery Congenital Heart Surgery 4-5 operations. On bivariate analysis, chylothorax patients had higher POD 1 FB (3.2 vs. 1.1%, p = 0.014), higher cumulative POD 2 FB (1.5 vs. -1.5%, p < 0.001), achieved negative daily FB by POD 1 less often (69% vs. 79%, p = 0.039), and had lower POD 1 urine output (1.9 vs. 3. 2 mL/kg/day, p ≤ 0.001) than those without chylothorax. We failed to identify an association between presence or absence of chylothorax and peak FB (5.2 vs. 4.9%, p = 0.9). Multivariable analysis shows that higher cumulative FB on POD 2 was associated with greater odds (odds ratio [OR], 95% CI) of chylothorax development (OR 1.5 [95% CI, 1.1-2.2]). Further multivariable analysis shows that chylothorax was independently associated with greater odds of longer durations of mechanical ventilation (OR 5.5 [95% CI, 3.7-8.0]), respiratory support (OR 4.3 [95% CI, 2.9-6.2]), use of inotropic support (OR 2.9 [95% CI, 2.0-4.3]), and longer hospital length of stay (OR 3.7 [95% CI, 2.5-5.4]).

CONCLUSIONS

Chylothorax after neonatal cardiac surgery for congenital heart disease (CHD) is independently associated with greater odds of longer duration of cardiorespiratory support and hospitalization. Higher early (POD 2) cumulative FB is associated with greater odds of chylothorax. Contemporary, prospective studies are needed to assess whether early fluid mitigation strategies decrease postoperative chylothorax development.

Oesophagopleural fistula after pneumonectomy: A systematic review and case series

INTRODUCTION

There is a paucity of data on the optimal management of oesophagopleural fistula (OPF) following pneumonectomy. The current published literature is limited to case reports and small case series. Although rare, OPF can have a significant impact on both the morbidity and mortality of patients.

METHODS

Two cases of OPF managed at our institution were reported. A systematic review was then conducted in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance concerning OPF following pneumonectomy. Demographic, operative and management data were analysed.

FINDINGS

Systematic review-identified data pertaining to 59 patients from 31 papers was collated. Median patient age was 59.5 years with pneumonectomy performed typically for malignancy (68%) or tuberculosis (19%). Median time from pneumonectomy to a diagnosis of OPF was 12.5 months. Twenty-five per cent of the patients had a synchronous bronchopleural fistula. Management of OPF in this setting is heterogenous. Conservative management was often reserved for asymptomatic or unfit patients. The remainder underwent endoscopic or surgical correction of the fistulae or a combination of the two with varying outcomes. Median follow-up was 18 months. All-cause mortality was 31% (18/59) with a median duration from pneumonectomy to death of 35 days (range 1-1,095).

CONCLUSIONS

Major heterogeneity of management for this rare complication hinders the introduction of standardised guidance of post-pneumonectomy OPF. Surgical and endoscopic intervention is feasible and can be successful in specialist centres. Adopting an multidisciplinary team approach involving both oesophagogastric and thoracic surgery teams and the introduction of a registry database of postoperative complications are likely to yield optimal outcomes.

Adrenal Hemorrhage: A Comprehensive Analysis of a Heterogeneous Entity-Etiology, Presentation, Management, and Outcomes

OBJECTIVE

To investigate the etiology, presentation, management, and outcomes of patients with adrenal hemorrhage (AH).

PATIENTS AND METHODS

Longitudinal study of consecutive adult patients with radiologically confirmed AH (January 1, 2017, through December 31, 2021).

RESULTS

Of the 363 patients with AH (median age, 62 years [interquartile range (IQR, 52-70 years]; 128 women [35%]), 338 (93%) had unilateral AH and 25 (7%) had bilateral AH. It was discovered incidentally in 152 patients (42%) and during the evaluation of trauma in 103 (28%), abdominal/back pain in 90 (25%), critical illness in 13 (4%), and symptoms of adrenal insufficiency in 5 (1%). Etiologies included postoperative complications in 150 patients (41%), trauma in 107 (30%), coagulopathy in 22 (6%), anticoagulant/antiplatelet therapy in 39 (11%), adrenal neoplasm in 22 (6%), and sepsis in 11, (3%). Overall, 165 patients (46%) were hospitalized, and no deaths occurred due to AH. Median (IQR) baseline AH size was 34 mm (24-40 mm) on the right and 29 mm (22-37 mm) on the left. Among 246 patients with follow-up imaging, AH resolution was complete in 155 (63%) and incomplete in 74 (30%) at a median of 15 months (IQR, 6-31 months). Patients with bilateral AH were more likely to have underlying coagulopathy (44% vs 3%) and to develop primary adrenal insufficiency (72% vs 0%) than those with unilateral AH (P<.001).

CONCLUSION

Often, AH presents as an incidental unilateral lesion with normal adrenal function, commonly attributed to postoperative complications or trauma. In contrast, bilateral AH is rare and typically linked to underlying coagulopathy, with primary adrenal insufficiency developing in most patients.

Exploring the Efficacy of the Paula Method of Muscle Exercises in Managing Low Anterior Resection Syndrome Using an Integrative Approach: A Preliminary Study

Low anterior resection syndrome (LARS) is a post-proctectomy consequence characterized by variable and unpredictable bowel function, including clustering, urgency, and incontinence, which significantly impacts the quality of life. Currently, there is no established gold-standard therapy for LARS.

Primary Study Objective

This study aimed to evaluate the effectiveness of the Paula method of exercise as part of an integrative treatment approach for patients with LARS.

Design

This preliminary study utilized a single-arm pretest-posttest design.

Setting

The study was conducted at a tertiary care medical center.

Participants

Five patients diagnosed with LARS completed the study.

Intervention

Participants underwent twelve weeks of individualized Paula method exercise sessions. Two questionnaires were employed to assess the severity of LARS and quality of life.

Primary Outcome Measures

(1) Low Anterior Resection Syndrome (LARS) Score; (2) Memorial Sloan Kettering Cancer Bowel Function Instrument (MSK-BFI); (3) Global Quality-of-Life (QOLS) Score ‎.

Results

All participants completing the 12-week Paula exercise regimen reported no difficulty in engaging with the exercises. Statistically significant improvements were observed in both the LARS score and MSK-BFI (P = .039 and P = .043, respectively, Wilcoxon Rank Sum test). While there were improvements in the global quality-of-life score and functional scales of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, these improvements did not reach statistical significance.

Conclusions

This preliminary study suggests that patients with LARS can successfully complete a 12-week exercise program using the Paula method, resulting in improved LARS scores. However, further investigation through larger, multicenter, randomized controlled trials is necessary to establish the efficacy of these exercises as a treatment for LARS.

Clinical comparative analysis of 3D printing-assisted extracorporeal pre-fenestration and Castor integrated branch stent techniques in treating type B aortic dissections with inadequate proximal landing zones

BACKGROUND

This study aims to compare the clinical effects of two distinct surgical approaches, namely 3D printing-assisted extracorporeal pre-fenestration and Castor integrated branch stent techniques, in treating patients with Stanford type B aortic dissections (TBAD) characterized by inadequate proximal landing zones.

METHODS

A retrospective analysis was conducted on 84 patients with type B aortic dissection (TBAD) who underwent thoracic endovascular aortic repair (TEVAR) with left subclavian artery (LSA) reconstruction at our center from January 2022 to July 2023. Based on the different surgical approaches, the patients were divided into two groups: the group assisted by 3D printing for extracorporeal pre-fenestration (n = 44) and the group using the castor integrated branch stent (n = 40). Clinical indicators: including general patient information, operative time, surgical success rate, intraoperative and postoperative complication rates, re-intervention rate, and mortality, as well as postoperative aortic remodeling, were compared between the two groups. The endpoint of this study is the post-TEVAR mortality rate in patients.

RESULTS

The surgical success rate and device deployment success rate were 100% in both groups, with no statistically significant difference (P > 0.05). However, the group assisted by 3D printing for extracorporeal pre-fenestration had a significantly longer operative time (184.20 ± 54.857 min) compared to the group using the castor integrated branch stent (152.75 ± 33.068 min), with a statistically significant difference (t = 3.215, p = 0.002, P < 0.05). Moreover, the incidence of postoperative cerebral infarction and beak sign was significantly lower in the group assisted by 3D printing for extracorporeal pre-fenestration compared to the castor-integrated branch stent group, demonstrating statistical significance. There were no significant differences between the two groups in terms of other postoperative complication rates and aortic remodeling (P > 0.05). Notably, computed tomography angiography images revealed the expansion of the vascular true lumen and the reduction of the false lumen at three specified levels of the thoracic aorta. The follow-up duration did not show any statistically significant difference between the two groups (10.59 ± 4.52 vs. 9.08 ± 4.35 months, t = 1.561, p = 0.122 > 0.05). Throughout the follow-up period, neither group experienced new endoleaks, spinal cord injuries, nor limb ischemia. In the castor-integrated branch stent group, one patient developed a new distal dissection, prompting further follow-up. Additionally, there was one case of mortality due to COVID-19 in each group. There were no statistically significant differences between the two groups in terms of re-intervention rate and survival rate (P > 0.05).

CONCLUSION

Both 3D printing-assisted extracorporeal pre-fenestration TEVAR and castor-integrated branch stent techniques demonstrate good safety and efficacy in treating Stanford type B aortic dissection with inadequate proximal anchoring. The 3D printing-assisted extracorporeal pre-fenestration TEVAR technique has a lower incidence of postoperative cerebral infarction and beak sign, while the castor-integrated branch stent technique has advantages in operative time.

Management and outcomes of hemorrhage after distal pancreatectomy: a multicenter study at high volume centers

BACKGROUND

Data on clinically relevant post-pancreatectomy hemorrhage (CR-PPH) are derived from series mostly focused on pancreatoduodenectomy, and data after distal pancreatectomy (DP) are scarce.

METHODS

All non-extended DP performed from 2014 to 2018 were included. CR-PPH encompassed grade B and C PPH. Risk factors, management, and outcomes of CR-PPH were evaluated.

RESULTS

Overall, 1188 patients were included, of which 561 (47.2 %) were operated on minimally invasively. Spleen-preserving DP was performed in 574 patients (48.4 %). Ninety-day mortality, severe morbidity and CR-POPF rates were 1.1 % (n = 13), 17.4 % (n = 196) and 15.5 % (n = 115), respectively. After a median interval of 8 days (range, 0-37), 65 patients (5.5 %) developed CR-PPH, including 28 grade B and 37 grade C. Reintervention was required in 57 patients (87.7 %). CR-PPH was associated with a significant increase of 90-day mortality, morbidity and hospital stay (p < 0.001). Upon multivariable analysis, prolonged operative time and co-existing POPF were independently associated with CR-PPH (p < 0.005) while a chronic use of antithrombotic agent trended towards an increase of CR-PPH (p = 0.081). As compared to CR-POPF, the failure-to-rescue rate in patients who developed CR-PPH was significantly higher (13.8 % vs. 1.3 %, p < 0.001).

CONCLUSION

CR-PPH after DP remains rare but significantly associated with an increased risk of 90-day mortality and failure-to-rescue.

An Analysis of Cost-Effectiveness and Clinical Outcomes of a Comprehensive Aortic Service in a Tertiary Center over One Year

BACKGROUND

Endovascular aortic repair (EVAR) is an established and attractive alternative to open surgical repair (OSR) of abdominal aortic aneurysms (AAA) due to its superior short-term safety profile. However, opinions are divided regarding its long-term cost-effectiveness. We compared the total yearly cost of running endovascular and OSR services in a single tertiary center to determine whether fenestrated EVAR (FEVAR) represents a clinically efficacious, affordable treatment option.

METHODS

A single-center retrospective review was performed on 109 patients undergoing a procedure related to index or previous abdominal aortic repair, with 1 year follow-up. Data was collected from the National Vascular Registry and hospital records. The primary outcome was cost per quality-adjusted life year. Secondary outcomes included 30-day mortality and morbidity, reintervention rates, length of hospital stay, aneurysm, and all-cause mortality at 1 year for elective index procedures.

RESULTS

The average cost per patient of all FEVAR was £16,041.53 (±8,857.54), £13,893.51 (±£21,425.25) for standard EVAR, and £15,357.22 (±£15,904.49) for OSR (FEVAR versus EVAR P = 0.55, FEVAR versus OSR P = 0.83, OSR versus EVAR P = 0.76). Of the secondary outcomes, significant findings included increased length of stay and respiratory morbidity for patients undergoing open versus endovascular repair. There was no significant difference in 30-day or 1-year mortality between groups.

CONCLUSIONS

FEVAR, EVAR, and OSR all represent cost-effective options for aortic repair with similar outcomes. Our data highlights the potential for FEVAR to present a viable alternative to open repair, particularly in higher-risk groups, when performed in specialist centers.

Ondansetron for Low Anterior Resection Syndrome (LARS): A Double-Blind, Placebo-Controlled, Cross-Over, Randomized Study

OBJECTIVE

The aim of the study was to examine the efficacity and safety of ondansetron, a serotonin receptor antagonist, to treat patients with low anterior resection syndrome (LARS).

BACKGROUND

LARS after rectal resection is common and debilitating. Current management strategies include behavioral and dietary modifications, physiotherapy, antidiarrheal drugs, enemas, and neuromodulation, but the results are not always satisfactory.

METHODS

This is a randomized, multicentric, double-blinded, placebo-controlled, and cross-over study. Patients with LARS (LARS score >20) no longer than 2 years after rectal resection were randomized to receive either 4 weeks of ondansetron followed by 4 weeks of placebo (O-P group) or 4 weeks of placebo followed by 4 weeks of ondansetron (P-O group). The primary endpoint was LARS severity measured using the LARS score; secondary endpoints were incontinence (Vaizey score) and irritable bowel syndrome quality of life (IBS-QoL questionnaire). Patients' scores and questionnaires were completed at baseline and after each 4-week treatment period.

RESULTS

Of 46 randomized patients, 38 were included in the analysis. From baseline to the end of the first period, in the O-P group, the mean (SD) LARS score decreased by 25% [from 36.6 (5.6) to 27.3 (11.5)] and the proportion of patients with major LARS (score >30) went from 15/17 (88%) to 7/17 (41%), ( P =0.001). In the P-O group, the mean (SD) LARS score decreased by 12% [from 37 (4.8) to 32.6 (9.1)], and the proportion of major LARS went from 19/21 (90%) to 16/21 (76%). After crossover, LARS scores deteriorated again in the O-P group receiving placebo, but further improved in the P-O group receiving ondansetron. Mean Vaizey scores and IBS QoL scores followed a similar pattern.

CONCLUSIONS

Ondansetron is a safe and simple treatment that appears to improve both symptoms and QoL in LARS patients.

The results of each working group (Definitions, Prevention, Management, and Epstein-Barr viral [EBV] load/Biomarker Monitoring) are presented in separate manuscripts within this volume of Pediatric Transplantation.

Challenges in evaluating pelvic floor physiotherapy based strategies in low anterior resection syndrome: a systematic review and qualitative analysis

AIM

Physiotherapy is an established treatment strategy for low anterior resection syndrome (LARS). However, data on its efficacy are limited. This is in part due to the inherent challenges in study design in this context. This systematic review aims to analyse the methodology of studies using pelvic floor physiotherapy for treatment of LARS to elucidate the challenges and limitations faced, which may inform the design of future prospective trials.

METHODOLOGY

A systematic review of the literature was undertaken through MEDLINE, Embase and Cochrane Library, yielding 345 unique records for screening. Five studies were identified for review. Content thematic analysis of study limitations was carried out using the Braun and Clarke method. Line-by-line coding was used to organize implicit and explicit challenges and limitations under broad organizing categories.

RESULTS

Key challenges fell into five overarching categories: patient-related issues, cancer-related issues, adequate symptomatic control, intervention-related issues and measurement of outcomes. Adherence, attrition and randomization contributed to potential bias within these studies, with imbalance in the baseline patient characteristics, particularly gender and baseline pelvic floor function scores. Outcome measurements consisted of patient-reported measures and quality of life measures, where significant improvements in bowel function according to patient-reported outcome measures were not reflected in the quality of life scores.

CONCLUSION

Upcoming trial design in the area of pelvic floor physiotherapy for faecal incontinence related to rectal cancer surgery can be cognisant of and design around the challenges identified in this systematic review, including the reduction of bias, exclusion of the placebo effect and the potential cultural differences in attitude towards a sensitive intervention.

The Safety of Dilation of Ileoanal Strictures With Mechanical or Balloon Dilation Is Similar Among Patients After Ileal Pouch-Anal Anastomosis

BACKGROUND

Anastomotic strictures occur in up to 38% of patients after ileal pouch-anal anastomosis (IPAA). We sought to compare the safety, effectiveness, and durability of mechanical dilation using a Hegar dilator to endoscopic through-the-scope balloon dilation (EBD) among IPAA patients with a rectal or ileoanal anastomotic stricture.

METHODS

We identified adult patients with an IPAA for ulcerative colitis (UC) who underwent a pouchoscopy between January 1, 2015, and December 31, 2019, at a single institution. We compared the effectiveness (median maximum diameter of dilation [MMD]), safety, and durability of mechanical and balloon dilation using standard statistical comparisons.

RESULTS

A total 74 patients had a stricture at the ileoanal anastomosis and underwent at least 1 mechanical or balloon dilation. The MMD with mechanical dilation was 19 (interquartile range [IQR], 18-20) mm for the first dilation and 20 (IQR, 18-20) mm for the second and third dilations. With balloon dilation, the MMD was 12 (IQR, 12-18) mm for the first dilation, 15 (IQR, 12-16.5) mm for the second dilation, and 18 (IQR, 15-18.5) mm for the third dilation. Patients undergoing mechanical dilation experienced a longer duration to second dilation (median 191 days vs 53 days: P < .001), with no difference in complications such as bleeding or perforation noted.

CONCLUSIONS

Among patients with ileoanal and rectal strictures, mechanical and balloon approaches to dilation demonstrated similar safety profiles and effectiveness. Mechanical dilation with Hegar dilators appears to be an effective and safe approach to the treatment of distal strictures after IPAA.

Recipient site scalp necrosis: A rare postoperative complication of hair transplantation

BACKGROUND

Recipient area scalp necrosis is considered a potential complication of hair transplantation, but has rarely been reported. A small number of patients have developed scalp necrosis after hair transplantation with the widely used Follicular unit excision (FUE) technique. There are no guidelines to prevent and manage this complication. The aim of this study was to provide an insight into the pathogenesis, prevention, and management of scalp necrosis following hair transplantation.

METHODS

From 2012 to 2021, among more than 10 000 patients who underwent hair transplantation, only three developed scalp necrosis in our clinical experience, besides, one patient transferred to our hospital because of scalp necrosis after undergoing hair transplantation. According to the disease etiology and patients' symptom, a combination of wound management and antimicrobial therapy was employed. This study was approved by the institutional ethics committee of Nanfang Hospital.

RESULTS

Of the four patients, three received timely treatment and had a good prognosis. Necrosis became confined and healed within 2-3 weeks. Grafts in the lesion area partially survived. In case 4, due to improper treatment at the early stage, the lesion developed extensively and deeply, which not only delayed wound healing, but also resulted in complete loss of grafts.

CONCLUSION

Preoperative prophylaxis, timely diagnosis, and immediate treatment of scalp necrosis can prevent serious complications and reduce morbidity after hair transplantation.

Postoperative Oral Rehydration and Regimented Follow-up Decrease Readmissions After Colorectal Surgery That Includes Ileostomies

BACKGROUND

Ileostomies constitute 15% to 43% of readmissions after colorectal surgery, often due to dehydration and acute kidney injury. Prior institutional interventions decreased readmissions but not among patients who underwent new ileostomies.

OBJECTIVE

To evaluate readmissions among patients who underwent new ileostomies after postoperative oral rehydration solution and standardized clinic visits.

DESIGN

Retrospective analysis of prospective database.

SETTINGS

Enhanced recovery colorectal surgery service.

PATIENTS

Patients who underwent new ileostomy before and after intervention.

INTERVENTIONS

Postoperative oral rehydration solution and postdischarge clinic visits with review of inputs/outputs, antimotility and appliance needs, and trained nurse reeducation 4 to 7 days after discharge, 30 days postoperatively, and every 1 to 2 weeks thereafter as needed.

MAIN OUTCOME MEASURES

Readmission rate due to dehydration/acute kidney injury (primary), emergency department visits, and readmission rates overall and for specific diagnoses. Analysis used univariate and weighted techniques.

RESULTS

A total of 312 patients (199 preintervention; 113 postintervention) were included, with a mean age of 59.0 years. Patients were predominantly White (94.9%) and evenly split between men and women. The most common diagnosis was diverticulitis (43.3%). The most common procedure was high anterior resection (38.8%), followed by low anterior resection (16.35%). Patient and procedure characteristics were well matched between groups. Multivariate analysis demonstrated that readmission rate due to dehydration/acute kidney injury significantly decreased between pre- and postintervention study groups (45.7% vs 16.5%, p = 0.039). Emergency department visits due to dehydration/acute kidney injury (12.0% vs 1.7%, p < 0.001) and readmissions from all causes (24.33% vs 10.6%, p = 0.005) also significantly decreased. Other complications were not significantly different between groups. Average stoma output 24 hours before (776 vs 625 mL, p = 0.005) and after (993 vs 890 mL, p = 0.025) discharge was significantly decreased in the postintervention group.

LIMITATIONS

Retrospective single-center study.

CONCLUSIONS

An oral rehydration solution and frequent standardized postdischarge visits led by trained nursing staff decreased readmissions and emergency department visits among patients who underwent new ileostomies after colorectal surgery. See Video Abstract .

LA REHIDRATACIN ORAL POSOPERATORIA Y EL SEGUIMIENTO REGLAMENTADO REDUCEN LOS REINGRESOS EN PACIENTES DE CIRUGA COLORRECTAL CON ILEOSTOMAS

ANTECEDENTES:Las ileostomías constituyen del 15 al 43% de los reingresos después de la cirugía colorrectal, a menudo debido a la deshidratación y la lesión renal aguda. Las intervenciones institucionales previas redujeron los reingresos, pero no entre los pacientes con nuevas ileostomías.OBJETIVO:Evaluar los reingresos entre pacientes con nuevas ileostomías después del uso de solución de rehidratación oral postoperatoria y visitas clínicas estandarizadas.DISEÑO:Análisis retrospectivo de base de datos prospectiva.AJUSTES:Servicio de cirugía colorrectal de recuperación mejorada.PACIENTES:Pacientes con ileostomía nueva antes y después de la intervención.INTERVENCIÓN(ES):Solución de rehidratación oral posoperatoria y visitas clínicas posteriores al alta con revisión de entradas/salidas, antimotilidad y necesidades de aparatos, y reeducación de enfermeras capacitadas 4-7 días después del alta, 30 días después de la operación y cada 1-2 semanas después, según sea necesario.PRINCIPALES MEDIDAS DE RESULTADO:Tasa de readmisión debido a deshidratación/lesión renal aguda (primaria), tasa de urgencias y de readmisión en general y para diagnósticos específicos. El análisis utilizó técnicas univariadas y ponderadas.RESULTADOS:Se incluyeron un total de 312 pacientes (199 preintervención; 113 postintervención), con una edad media de 59,0 años. Los pacientes eran predominantemente blancos (94,9%) y se dividieron equitativamente entre hombres y mujeres. El diagnóstico más frecuente fue diverticulitis (43,3%).

Association of race, demographic and socioeconomic factors with failure to rescue after hepato-pancreato-biliary surgery in the United States

BACKGROUND

We aimed to describe the association of patient-related factors such as race, socioeconomic status, and insurance on failure to rescue (FTR) after hepato-pancreato-biliary (HPB) surgeries.

METHODS

Using the National Inpatient Sample, we analyzed 98,788 elective HPB surgeries between 2004 and 2017. Major and minor complications were identified using ICD9/10 codes. We evaluated mortality rates and FTR (inpatient mortality after major complications). We used multivariate logistic regression analysis to assess racial, socioeconomic, and demographic factors on FTR, adjusting for covariates.

RESULTS

Overall, 43 % of patients (n = 42,256) had pancreatic operations, 36% (n = 35,526) had liver surgery, and 21% (n = 21,006) had biliary interventions. The overall major complication rate was 21% (n = 20,640), of which 8% (n = 1655) suffered FTR. Factors independently associated with increased risk for FTR were male sex, older age, higher Charlson Comorbidity Index, Hispanic ethnicity, Asian or other race, lower income quartile, Medicare insurance, and southern region hospitals.

CONCLUSIONS

Medicare insurance, male gender, Hispanic ethnicity, and lower income quartile were associated with increased risk for FTR. Efforts should be made to improve the identification and subsequent treatment of complications for those at high risk of FTR.

Long term persistence and risk factors for anorectal symptoms following low anterior resection for rectal cancer

BACKGROUND

Rectal cancer is commonly treated by chemoradiation therapy, followed by the low anterior resection anal sphincter-preserving surgery, with a temporary protecting ileostomy. After reversal of the stoma a condition known as low anterior resection syndrome (LARS) can occur characterized by a combination of symptoms such as urgent bowel movements, lack of control over bowel movements, and difficulty fully emptying the bowels. These symptoms have a significant negative impact on the quality of life for individuals who have survived the cancer. Currently, there is limited available data regarding the presence, risk factors, and effects of treatment for these symptoms during long-term follow-up.

AIMS

To evaluate long term outcomes of low anterior resection surgery and its correlation to baseline anorectal manometry (ARM) parameters and physiotherapy with anorectal biofeedback (BF) treatment.

METHODS

One hundred fifteen patients (74 males, age 63 ± 11) who underwent low anterior resection surgery for rectal cancer were included in the study. Following surgery, patients were managed by surgical and oncologic team, with more symptomatic LARS patients referred for further evaluation and treatment by gastroenterologists. At follow up, patients were contacted and offered participation in a long term follow up by answering symptom severity and quality of life (QOL) questionnaires.

RESULTS

80 (70%) patients agreed to participate in the long term follow up study (median 4 years from stoma reversal, range 1-8). Mean time from surgery to stoma closure was 6 ± 4 months. At long term follow up, mean LARS score was 30 (SD 11), with 55 (69%) patients classified as major LARS (score > 30). Presence of major LARS was associated with longer time from surgery to stoma reversal (6.8 vs. 4.8 months; p = 0.03) and with adjuvant chemotherapy (38% vs. 8%; p = 0.01). Patients initially referred for ARM and BF were more likely to suffer from major LARS at long term follow up (64% vs. 16%, p < 0.001). In the subgroup of patients who underwent perioperative ARM (n = 36), higher maximal squeeze pressure, higher maximal incremental squeeze pressure and higher rectal pressure on push were all associated with better long-term outcomes of QOL parameters (p < 0.05 for all). 21(54%) of patients referred to ARM were treated with BF, but long term outcomes for these patients were not different from those who did not perform BF.

CONCLUSIONS

A significant number of patients continue to experience severe symptoms and a decline in their quality of life even 4 years after undergoing low anterior resection surgery. Prolonged time until stoma reversal and adjuvant chemotherapy emerged as the primary risk factors for a negative prognosis. It is important to note that referring patients for anorectal physiology testing alone tended to predict poorer long-term outcomes, indicating the presence of selection bias. However, certain measurable manometric parameters could potentially aid in identifying patients who are at a higher risk of experiencing unfavorable functional outcomes. There is a critical need to enhance current treatment options for this patient group.

A preoperative supervised exercise program potentially improves long-term survival after elective abdominal aortic aneurysm repair

OBJECTIVE

A preoperative supervised exercise program (SEP) improves cardiorespiratory fitness and perioperative outcomes for patients undergoing elective abdominal aortic aneurysm (AAA) repair. The aim of this study was to assess the effect of a preoperative SEP on long-term survival of these patients. A secondary aim was to consider long-term changes in cardiorespiratory fitness and quality of life.

METHODS

Patients scheduled for open or endovascular AAA repair were previously randomized to either a 6-week preoperative SEP or standard management, and a significant improvement in a composite outcome of cardiac, pulmonary, and renal complications was seen following SEP. For the current analysis, patients were followed up to 5 years post-surgery. The primary outcome for this analysis was all-cause mortality. Data were analyzed on an intention to treat (ITT) and per protocol (PP) basis, with the latter meaning that patients randomized to SEP who did not attend any sessions were excluded. The PP analysis was further interrogated using a complier average causal effect (CACE) analysis on an all or nothing scale, which adjusts for compliance. Additionally, patients who agreed to follow-up attended the research center for cardiopulmonary exercise testing and/or provided quality of life measures.

RESULTS

ITT analysis demonstrated that the primary endpoint occurred in 24 of the 124 participants at 5 years, with eight in the SEP group and 16 in the control group (P = .08). The PP analysis demonstrated a significant survival benefit associated with SEP attendance (4 vs 16 deaths; P = .01). CACE analysis confirmed a significant intervention effect (hazard ratio, 0.36; 95% confidence interval, 0.16-0.90; P = .02). There was no difference between groups for cardiorespiratory fitness measures and most quality of life measures.

CONCLUSIONS

These novel findings suggest a long-term mortality benefit for patients attending a SEP prior to elective AAA repair. The underlying mechanism remains unknown, and this merits further investigation.

Effects of Two Different Cold Application Methods After Rhinoplasty: A Randomized Clinical Trial

The aim of this prospective, randomized controlled clinical trial was to evaluate the effects of two methods of cold application on eye ecchymosis, periorbital edema, pain around the eyes and face, and patient comfort in postoperative rhinoplasty patients. Patients were randomly divided and evaluated in two groups: an ice in disposable latex gloves (IDLG) group and a cooling gel eye mask (CGEM) group. We used the CONSORT checklist to report the study. There were no significant differences between the groups in terms of age, gender, preoperative blood pressure, respiration, fever status, oxygen saturation, or postoperative vital signs. Patients in the IDLG group had significantly higher scores for pain around the eyes, facial pain, and periorbital edema on the first postoperative day, and significantly higher facial edema scores during the first postoperative hour (p ≤ .05). Patients in the CGEM group reported that they slept more comfortably (p ≤ .05). The results of our study showed that CGEMs reduce pain, periorbital edema, and facial edema after rhinoplasty.

Frequency of Complications After Kidney Transplant in the Early Postoperative Period

OBJECTIVES

Complications after kidney transplant can be divided into surgical and nonsurgical. Our study investigated the incidence of postoperative complications and types of complications in a single center.

MATERIALS AND METHODS

We retrospectively analyzed the occurrence of postoperative complications in 220 patients who underwent kidney transplantation at the Republican Scientific Center for Emergency Medical Care (Tashkent, Republic of Uzbekistan) from January 2019 to October 2022.

RESULTS

Among the 220 patients, various types of complications were observed in 42 cases (19.1%). Of these, 31 patients (73.8%) had surgical complications and 11 patients (26.2%) had nonsurgical complications. Surgical complications included hematoma of the postoperative wound in 8 patients (19.2%), thrombosis of the graft artery in 1 patient (2.4%), thrombosis of the venous anastomosis in 1 patient (2.4%), lymphocele of the postoperative wound in 7 patients (16.6%), wound infections 4 patients (9.5%), bleeding from the arterial anastomosis 2 patients (4.7%), bleeding from the venous anastomosis 1 patient (2.4%), kink of the venous anastomosis in 3 patients (7.2%), postoperative hernia in 2 patients (4.7%), and urological complications in the form of ureteral necrosis in 2 patients (4.7%). Nonsurgical complications included hyperacute rejection, which led to the removal of the graft, in 2 patients (4.8%), acute cellular rejection of the graft, which was successfully treated with methylprednisolone pulse therapy, in 4 patients (9.5%), delayed graft function in 1 patients (2.4%) case, and posttransplant diabetes mellitus in 4 patients (9.5%).

CONCLUSIONS

Despite the frequency of postoperative complications, timely assistance and further monitoring of patients can lead to normal functioning of the kidney transplant, except for cases of hyperacute rejection.

The impact of negative pressure wound therapy on surgical wound infection, hospital stay and postoperative complications after spinal surgery: A meta-analysis

To systematically assess the effect of negative pressure wound therapy (NPWT) on postoperative surgical wound infection, length of hospital stay and postoperative complications after spinal surgery. Relevant studies on the application of NPWT in spinal surgery were conducted via a computerised database search, including PubMed, EMBASE, Web of Science, MEDLINE, Cochrane Library, China National Knowledge Infrastructure (CNKI) and Wanfang, from inception to June 2023. The identified literature was rigorously screened and data extraction was performed by two investigators independently. The quality of the relevant studies was evaluated using the Newcastle-Ottawa scale (NOS). The effect size for count data was determined by the odds ratio (OR), while the impact size for measurement data was expressed as the standardised mean difference (SMD). The 95% confidence interval (CI) was calculated for each effect magnitude. Stata 17.0 software was used for the meta-analysis. Ten papers, totalling 1448 patients, were finally included. This study demonstrated that NPWT led to a statistically significant reduction in the occurrence of postoperative surgical wound infections (OR: 0.377, 95% CI: 0.238-0.598, p < 0.001), fewer postoperative complications (OR: 0.526, 95% CI: 0.360-0.770, p = 0.001) and a shortened hospital stay (SMD: -0.678, 95%CI: -1.324 to -0.031, p = 0.040) after spinal surgery compared with the control group. When compared with other treatment approaches, NPWT also demonstrated a substantial reduction in surgical wound infections and postoperative complications, as well as a shorter duration of hospitalisation after spinal surgery.

Applying Artificial Intelligence to Predict Complications After Endovascular Aneurysm Repair

Objective: Complications after Endovascular Aneurysm Repair (EVAR) can be fatal. Patient follow-up for surveillance imaging is becoming more challenging as fewer patients are seen, particularly after the first year. The aim of this study was to develop an artificial intelligence model to predict the complication probability of individual patients to better identify those needing more intensive post-operative surveillance. Methods: Pre-operative CTA 3D reconstruction images of AAA from 273 patients who underwent EVAR from 2011-2020 were collected. Of these, 48 patients had post-operative complications including endoleak, AAA rupture, graft limb occlusion, renal artery occlusion, and neck dilation. A deep convolutional neural network model (VascAI©) was developed which utilized pre-operative 3D CT images to predict risk of complications after EVAR. The model was built with TensorFlow software and run on the Google Colab Platform. An initial training subset of 40 randomly selected patients with complications and 189 without were used to train the AI model while the remaining 8 positive and 36 negative cases tested its performance and prediction accuracy. Data down-sampling was used to alleviate data imbalance and data augmentation methodology to further boost model performance. Results: Successful training was completed on the 229 cases in the training set and then applied to predict the complication probability of each individual in the held-out performance testing cases. The model provided a complication sensitivity of 100% and identified all the patients who later developed complications after EVAR. Of 36 patients without complications, 16 (44%) were falsely predicted to develop complications. The results therefore demonstrated excellent sensitivity for identifying patients who would benefit from more stringent surveillance and decrease the frequency of surveillance in 56% of patients unlike to develop complications. Conclusion: AI models can be developed to predict the risk of post-operative complications with high accuracy. Compared to existing methods, the model developed in this study did not require any expert-annotated data but only the AAA CTA images as inputs. This model can play an assistive role in identifying patients at high risk for post-EVAR complications and the need for greater compliance in surveillance.

Suction in Percutaneous Nephrolithotripsy: Evolution, Development, and Outcomes from Experimental and Clinical studies. Results from a Systematic Review

CONTEXT

Controversy exists regarding the therapeutic benefit of suction use during percutaneous nephrolithotripsy (PCNL).

OBJECTIVE

To review and highlight the options available in the use of suction for PCNL, and to discuss their strengths and limitations.

EVIDENCE ACQUISITION

A systematic literature search was performed using Scopus, EMBASE, and PubMed. Thirty four studies were included. There was one ex vivo study. Among clinical studies, 24 used a vacuum/suctioning sheath and nine a handpiece suction device/direct-in-scope suction. The suction technique was employed in standard, mini-PCNL, supermini-PCNL, and enhanced supermini‑PCNL techniques.

EVIDENCE SYNTHESIS

Handpiece suction devices demonstrated better safety and efficiency in treating large stones than nonsuction PCNL and in a much shorter time. Trilogy and ShockPulse-SE were equally effective, safe, and versatile for standard PCNL and mini-PCNL. The heavier handpiece makes Trilogy less ergonomically friendly. Laser suction handpiece devices can potentiate laser lithotripsy by allowing for better laser control with simultaneous suction of small fragments and dust. Integrated suction-based sheaths are available in reusable and disposable forms for mini-PCNL only. Mini-PCNL with suction reported superior outcomes for operative time and stone-free rate to mini-PCNL. This also helped minimize infectious complications by a combination of intrarenal pressure reduction and faster aspiration of irrigation fluid reducing the risk of sepsis, enhance intraoperative vision, and improve lithotripsy efficiency, which makes it a very attractive evolution for PCNL.

CONCLUSIONS

Suction devices in PCNL are reforming the way PCNL is being done. Adding suction to mini-PCNL reduces infectious complications and improves the stone-free rate. Our review shows that despite the limited evidence, suction techniques appear to improve PCNL outcomes.

PATIENT SUMMARY

In this review, we looked at the intra- and perioperative outcomes of percutaneous nephrolithotripsy (PCNL) with the addition of suction. With better stone fragmentation and fewer postoperative infections, this technology is very useful particularly for mini-PCNL.

Current use of drains and management of seroma following mastectomy and axillary surgery: results of a United Kingdom national practice survey

PURPOSE

Up to 40% of the 56,000 women diagnosed with breast cancer each year in the UK undergo mastectomy. Seroma formation following surgery is common, may delay wound healing, and be uncomfortable or delay the start of adjuvant treatment. Multiple strategies to reduce seroma formation include surgical drains, flap fixation and external compression exist but evidence to support best practice is lacking. We aimed to survey UK breast surgeons to determine current practice to inform the feasibility of undertaking a future trial.

METHODS

An online survey was developed and circulated to UK breast surgeons via professional and trainee associations and social media to explore current attitudes to drain use and management of post-operative seroma. Simple descriptive statistics were used to summarise the results.

RESULTS

The majority of surgeons (82/97, 85%) reported using drains either routinely (38, 39%) or in certain circumstances (44, 45%). Other methods for reducing seroma such as flap fixation were less commonly used. Wide variation was reported in the assessment and management of post-operative seromas. Over half (47/91, 52%) of respondents felt there was some uncertainty about drain use after mastectomy and axillary surgery and two-thirds (59/91, 65%) felt that a trial evaluating the use of drains vs no drains after simple breast cancer surgery was needed.

CONCLUSIONS

There is a need for a large-scale UK-based RCT to determine if, when and in whom drains are necessary following mastectomy and axillary surgery. This work will inform the design and conduct of a future trial.

Coral Reef Aorta: Literature Review and Analysis of the Published Cases in the Last 20 Years

BACKGROUND

Coral reef aorta (CRA) is defined by the presence of heavily calcified exophytic plaques that protrude into the aortic lumen. However, the exact causes and development of this condition are still not fully understood. When the aortic branches are affected, it can result in various symptoms. Despite ongoing research, there is currently no established consensus on the best treatment for CRA. This review aims to examine the latest findings regarding the clinical presentation and approach to treating patients with CRA.

METHODS

We conducted a systematic electronic search of the literature using the PubMed and Embase databases. Throughout the search, we adhered to the guidelines outlined in the PRISMA framework. From the identified publications, we extracted information pertaining to patients' characteristics, symptoms, and types of treatment from a total of 124 cases reported over the past 20 years. The primary focus of our analysis was to assess the improvement of signs and symptoms, as well as to evaluate any postoperative complications. To achieve this, we performed both descriptive and inferential analyses on the collected data. Additionally, we conducted subgroup analyses based on treatment types and symptoms observed at presentation, presenting the findings in the form of odds ratios (ORs).

RESULTS

After removing duplicate articles, we carefully screened the titles of 67 retrieved articles and excluded those that did not align with the purpose of our study. Subsequently, we thoroughly analyzed the remaining 41 articles along with their references, ultimately including 29 studies that were deemed most relevant for our systematic review. We examined a total of 124 cases of patients diagnosed with CRA, comprising 77 (62.1%) females and 48 (38.7%) males, with a mean age of 59 years (range: 37-84). The predominant signs and symptoms observed were intermittent claudication, reported in 57 (46.0%) patients, followed by refractory hypertension in 45 (36.3%) patients, intestinal angina in 28 (22.6%) patients, and renal insufficiency in 15 (12.1%) patients. Among the treated patients, 110 (88.7%) underwent open surgery repair (OSR), 11 (8.9%) received endovascular treatment, and 3 (2.4%) underwent laparoscopy. Postoperatively, a significant number of patients experienced substantial relief or complete resolution of their symptoms, as well as improved control of hypertension and renal function. In the group of patients treated with OSR, the inhospital stay mortality rate was 10.9%, the morbidity rate was 28.2%, and the reintervention rate was 15.5%. The high mortality rate during hospital stays in this group may be associated with such invasive procedures performed on patients who have substantial cardiovascular burden and multiple comorbidities. Conversely, no postoperative complications were reported in the group of patients treated with endovascular procedures or laparoscopic surgery.

CONCLUSIONS

While coral reef aorta (CRA) is considered a rare condition, it is crucial for the medical community to remain vigilant about its diagnosis, particularly in patients presenting with symptoms such as intermittent claudication, refractory hypertension, renal impairment, or intestinal angina. Based on the findings of this review, both OSR and endovascular treatment have shown promise as viable therapeutic options. Although endovascular therapies may not always be feasible or may have reduced durability in these calcified bulky lesions, they should be considered in patients with multiple comorbidities, due to the high postoperative mortality rates associated with more invasive approaches. Additionally, these endoluminal procedures have demonstrated good patency rates during the 18-month follow-up period. It is essential to emphasize that the treatment strategy should be determined on a case-by-case basis, involving a multidisciplinary team to tailor it to the specific needs of each individual patient.

Managing complications following cosmetic surgery after the COVID pandemic: A study of a year at an NHS plastic surgery unit

BACKGROUND

The study was an analysis of patients managed by plastic surgery services at Heatherwood and Wexham Park hospitals during the calendar year 2022 for complications following cosmetic surgeries performed both internationally and within the United Kingdom.

METHODS

Patients were identified via local databases and encounters and management confirmed with retrospective studies of patient electronic medical records.

RESULTS

23 patients were managed during the year 2022 for complications post cosmetic surgery. 91% (n = 21) of complications were related to breast cosmetic surgery and/or abdominoplasties. 78% (n = 18) of patients presented within the first two months following their procedure. The most common complications identified were wound dehiscence 43% (n = 10), post-operative infection 39% (n = 9) and seromas 30% (n = 7). The most common country selected for surgery by patients was Turkey with 48% (n = 11) of managed patients. 52% (n = 12) of cases were managed conservatively and 48% (n = 11) of cases required invasive procedures including surgery. 87% (n = 20) of patients were discharged with completed treatment.

CONCLUSION

Cosmetic surgery and tourism are an in-demand phenomenon and appear here to stay. The stringent regulatory and legal processes in place in the UK may not be applicable abroad to the detriment of patient care. Greater effort is needed to increase public awareness to the risks involved in seeking international options and how to self-screen suitable clinics. Ongoing current national auditing may need to be expanded to understand the true impact on NHS units in dealing with the aftermath of these surgical expeditions.

Management of basilar fenestration aneurysms: a systematic review with an illustrative case report

BACKGROUND

Basilar artery (BA) fenestration aneurysm (BAFA) is a rare phenomenon commonly accompanying other aneurysms. Treatment is challenging, and few cases have been reported. This review investigated the management outcomes of BAFAs.

METHODS

Publication databases were searched to identify studies evaluating outcomes of endovascular treatment (EVT) and microsurgical treatment of BAFAs from inception through 2021. Outcomes (clinical, angiographic, postoperative complications, and retreatment rates) were collected and analyzed. The authors present their case of a patient treated for a BAFA.

RESULTS

Including the authors' case, 184 patients with 209 BAFAs were reported in 68 studies. Most patients (130/175; 74.3%) presented with ruptured aneurysms, most commonly involving the proximal segment of the BA. Most BAFAs were small (52/103, 50.5%) and saccular (119/143, 83.2%). Most patients underwent EVT (143/184, 77.7%); the rest underwent microsurgery. Postoperative complications after EVT occurred in 10 (8.3%) of 120 patients, with 4 of the 10 experiencing strokes. At clinical follow-up, most EVT patients (74/86, 86.0%) showed good outcomes; 3.9% (2/51) had died. Most aneurysms managed with EVT (56/73, 76.7%) showed complete occlusion at follow-up; 7.3% (8/109) were retreated. Postoperative complications occurred in 62.2% (23/37) of microsurgical patients; 5 (21.7%) of the 23 experienced strokes. All patients showed good clinical outcomes at follow-up. Most aneurysms (22/28, 78.6%) treated microsurgically showed complete occlusion at angiographic follow-up, with no retreatment required.

CONCLUSION

BAFAs are often symptomatic; thus, treatment is challenging. By the 2000s, treatment had moved from microsurgical to endovascular modalities, with good clinical and angiographic outcomes.

PHYSIO+++: protocol for a pilot randomised controlled trial assessing the feasibility of physiotherapist-led non-invasive ventilation for patients with hypoxaemia following abdominal surgery

INTRODUCTION

Few clinical trials have investigated physiotherapy interventions to treat hypoxaemia following abdominal surgery. The objective of this study is to determine the feasibility and safety of conducting a clinical trial of physiotherapist-led non-invasive ventilation (NIV).

METHODS AND ANALYSIS

This single-centre, 50-patient, parallel-group, assessor blinded, pilot feasibility randomised controlled trial with concealed allocation will enrol spontaneously ventilating adults with hypoxaemia within 72 hours of major abdominal surgery. Participants will receive either (1) usual care physiotherapy of a single education session (talk), daily walking of 10-15 min (walk) and four sessions of coached deep breathing and coughing (breathe) or (2) usual care physiotherapy plus four 30 min sessions of physiotherapist-led NIV delivered over 2 postoperative days. Primary feasibility and safety outcome measures are; number of eligible patients recruited per week, total time of NIV treatment delivered, acceptability of treatments to patients and clinicians and incidence of adverse events. Secondary feasibility outcomes include measures of recruitment and treatment adherence. Exploratory outcome measures include change in respiratory parameters, postoperative pulmonary complications, length of hospital stay, health-related quality of life, postoperative activity levels and mortality.

ETHICS AND DISSEMINATION

Ethics approval has been obtained from the relevant institution. Results will be published to inform future research.

Managing common neurological complications following cardiac surgery

Despite recent technological advances in the field of surgery, neurological complications remain a significant post-operative issue. Two of the most common post-operative complications are delirium and post-operative cognitive decline, which occur frequently after cardiac surgery. This article provides an overview of delirium and post-operative cognitive decline, including risk factors, signs and symptoms, and diagnosis. The author also considers the nurse's role in managing patients who are at risk of, or have experienced, delirium or post-operative cognitive decline after cardiac surgery.

Surgical Versus Image-Guided Interventions in the Management of Complications After Liver Transplantation

Liver transplantation is a technically demanding surgical procedure with known complications, and the optimal approach to addressing vascular and biliary complications requires a coordinated effort between surgical and interventional radiology teams. Vascular complications involving the hepatic artery, portal vein, or hepatic veins can be characterized by their mechanism, chronicity, and timing of presentation. These factors help determine whether the optimal therapeutic approach is surgical or endovascular. Very early presentation in the perioperative period favors surgical revision, while later presentation is best addressed endovascularly. Biliary complications can be categorized as leaks or strictures, and coordinated surgical, endoscopic, and percutaneous management is needed to address these types of complications. Through advances in technique and the management of complications, outcomes after liver transplantation continue to improve.

Transplant Hepatic Artery Complications

Hepatic artery complications can be divided into 2 different categories, nonocclusive and steno-occlusive disease. Steno-occlusive disease is a collective term that encompasses hepatic artery thrombosis, hepatic artery stenosis, and hepatic arterial kinks, while nonocclusive arterial disease encompasses less than 5% of complications and is a collective term used to describe arteriovenous fistulae, pseudoaneurysms, arterial rupture and nonocclusive hepatic artery hypoperfusion syndrome. This article details the angiographic techniques and definitions needed to accurately diagnose arterial transplant complications and describes the technical aspects and results of endoluminal management of these arterial complications. In addition, this article discusses the presentation, etiology and indications for treatment, including surgical management of these various complications.

Moxibustion for Managing Postoperative Urinary Retention After Hemorrhoidectomy and Anorectal Surgeries: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

PURPOSE

Common surgical procedures for conditions affecting the anus and rectum such as hemorrhoidectomy are associated with high risks of postoperative urinary retention (POUR). Little is known about the efficacy of moxibustion in managing POUR after such surgical procedures. This systematic review and meta-analysis aimed to review the related literature and synthesize data on the effectiveness of moxibustion in managing POUR after common anorectal surgeries.

DESIGN

A systematic review and meta-analysis of randomized controlled trials (RCTs).

METHODS

PubMed, EMBASE, CENTRAL, Chinese National Knowledge Infrastructure (CNKI), VIP information, and Wanfang databases were searched to October 1, 2021 using the keywords urinary retention, moxibustion, and moxa. Randomized controlled trials (RCTs) investigating patients who had developed POUR after hemorrhoidectomy or other anorectal surgeries were eligible for inclusion. Patients receiving moxibustion formed the intervention group and the control group received usual care alone. Primary outcomes were markedly effective rate, defined as spontaneous voiding with complete symptom relief within 30 to 60 minutes after treatment; and total effective rate (ie, markedly effective rate plus effective rate, defined as spontaneous voiding with partial relief of symptoms within 60 minutes to 4 hours after treatment). Secondary outcome was time to first urination after treatment.

FINDINGS

Thirty-four RCTs met the eligibility criteria. Pooled analysis revealed that the markedly effective rate was significantly higher in the moxibustion group than that in the control group (pooled RR = 2.53, 95% CI = 2.17-2.95), and the total effective rate in the moxibustion group was also higher than that in the control group (pooled RR = 5.02, 95% CI = 4.01-6.28). The intervention group had significantly shorter times to first urination than controls (pooled effect = -2.81, 95% CI = -2.06 to -3.56).

CONCLUSIONS

Moxibustion appears superior to usual care in relieving POUR after common anorectal surgeries. Future studies are still warranted to confirm these findings.

Endoscopic Management of Surgical Complications of Bariatric Surgery

Bariatric surgery, although highly effective, may lead to several surgical complications like ulceration, strictures, leaks, and fistulas. Newer endoscopic tools have emerged as safe and effective therapeutic options for these conditions. This article reviews post-bariatric surgery complications and the role of endoscopy in their management.

Use of a Digital Air Leak Detection Device to Decrease Chest Tube Duration

BACKGROUND

The aim of this evidence-based practice project was to determine if a digital air leak detection device could speed the identification of chest tube air leak cessation in patients after pulmonary lobectomy. Staff members assessing air leaks have varying levels of expertise, and the digital device is a limited resource in the study institution. A chest tube management algorithm is necessary to standardize care and determine which patients are most likely to benefit.

IMPLEMENTATION

Twenty-five consecutive patients who underwent pulmonary lobectomy during the study period and continued to have a chest tube air leak on postoperative day 3 were monitored with digital air leak detection devices. The Mann-Whitney U test was used to compare chest tube duration and hospital length of stay between patients with digital devices and 259 patients who had traditional analog air leak detection devices (historical data from the departmental database over the previous 2 years).

EVALUATION

Median chest tube duration and hospital stay were 1 day less in patients with digital devices than in those with traditional analog devices (P = .01 and P = .004, respectively), with a cost savings of $2659 per hospital day. Reductions in chest tube duration and length of stay aided in the development of a chest tube management algorithm.

CONCLUSIONS

Critical care nurses are valued team members who treat patients after lung resections. Digital air leak detection devices can help them assess air leaks more accurately, benefiting the patients in their care.

Functional sequelae after pancreatic resection for cancer

The morbidity and mortality of pancreatic cancer surgery has seen substantial improvement due to the standardization of surgical techniques, the optimization of perioperative multidisciplinary management and the organization of specialized care systems. The identification and treatment of postoperative functional and nutritional sequelae have thereby become major issues in patients who undergo pancreatic surgery. This review addresses the functional sequelae of pancreatic resection for cancerous and pre-cancerous lesions (excluding chronic pancreatitis). Its aim is to specify the prevalence and severity of sequelae according to the type of pancreatic resection and to document, where appropriate, the therapeutic management. Exocrine pancreatic insufficiency (ExPI) is observed in nearly one out of three patients at one year after surgery, and endocrine pancreatic insufficiency (EnPI) is present in one out of five patients after pancreatoduodenectomy (PD) and one out of three patients after distal pancreatectomy (DP). In addition, digestive functional disorders may appear, such as delayed gastric emptying (DGE), which affects 10 to 45% of patients after PD and nearly 8% after DP. Beyond these functional sequelae, pancreatic surgery can also induce nutritional and vitamin deficiencies secondary to a lack of uptake for certain vitamins or to the loss of absorption site in the duodenum. In addition to the treatment of ExPI with oral pancreatic enzymes, nutritional management is based on a high-calorie, high-protein diet with normal lipid intake in frequent small feedings, combined with vitamin supplementation adapted to monitored deficiencies. Better knowledge of the functional consequences of pancreatic cancer surgery can improve the overall management of patients.

The effect of early follow-up after open cardiac surgery in a student clinic

Objectives. Readmission rates following open cardiac surgery are high, affecting patients and the cost of care. This study aimed to investigate the effect of early additional follow-up after open cardiac surgery when 5th-year medical students conducted follow-ups under the supervision of physicians. The primary endpoint was unplanned cardiac-related readmissions within one year. The secondary outcomes were the detection of impending complications and health-related quality of life (HRQOL). Methods. Patients undergoing open cardiac surgery were prospectively included. For intervention, additional follow-up visits, including point-of-care ultrasound, were conducted by supervised 5th-year medical students on postoperative days 3, 14 and 25. Unplanned cardiac-related readmissions, including emergency department visits, were registered within the first year of surgery. Danish National Health Survey 2010 questionnaire was used for HRQOL. In standard follow-up, all patients were seen 4-6 weeks postoperative. Results. For data analysis, 100 of 124 patients in the intervention group and 319 of 335 patients in the control group were included. The 1-year unplanned readmission rates did not differ; 32% and 30% in the intervention and control groups, respectively (p = 0.71). After discharge, 1% of patients underwent pericardiocentesis. The additional follow-up initiated scheduled drainage, contrary to more unscheduled/acute drainages in the control group. Pleurocentesis was more common in the intervention group (17% (n = 17) vs 8% (n = 25), p = 0.01) and performed earlier. There was no difference between groups on HRQOL. Conclusion. Supervised student-led follow-up of newly cardiac-operated patients did not alter readmission rates or HRQOL but may detect complications earlier and initiate non-emergent treatment of complications.

Common postbariatric surgery emergencies for the acute care surgeon: What you need to know

ABSTRACT

The field of bariatric and metabolic surgery has changed rapidly over the past two decades, with an exponential increase in case volumes being performed because of its proven efficacy for morbid obesity and obesity-related comorbidities. Although this increased volume of procedures has been accompanied by significant decrease in postoperative complication rates, there are numerous potential complications after bariatric surgery that may require urgent or emergent surgical evaluation or interventions. Many of these risks extend well beyond the early postoperative period and can present months to years after the index procedure. Acute care surgeons are increasingly covering most or all of the emergency general surgery services at many centers and must be familiar with the numerous bariatric surgical procedures being performed and their individual complication profile to provide optimal care for these frequently challenging patients. This article provides a focused and concise review of the common bariatric procedures being performed, their early and late complication profiles, and a practical guide to the optimal diagnostic evaluations, surgical interventions, and perioperative management options. The author group includes both acute care surgeons and bariatric surgeons with significant experience in the emergency management of the complicated postbariatric surgical patient.

PDCA cycle management combined with detailed management of postoperative deep vein thrombosis in patients undergoing hip replacement surgery

OBJECTIVE

This study aimed to analyze and explore the effect of Plan-Do-Check-Act (PDCA) cycle management combined with detailed management on postoperative deep venous thrombosis in patients undergoing hip replacement surgery.

PATIENTS AND METHODS

Patients who underwent hip replacement surgery in our hospital between November 2021 and April 2023 were recruited for the study. After screening, patients who met all the inclusion criteria were assessed for eligibility. Finally, 80 adults were enrolled. All patients were assigned into observation and control groups (1:1) according to the sequence of admission, i.e., patients admitted between November 2021 and August 2022 were the control group, and patients admitted between September 2022 and April 2023 were the observation group.

RESULTS

The intraoperative blood loss and hospital stay in the observation group were significantly less than those in the control group (p<0.05). After the intervention, the levels of plasma prothrombin time (PT), thrombin time (TT), and thromboplastin time (APTT) in the observation group were higher than those in the control group, and the DD level was lower than that in the control group (p<0.05). There was one patient in the observation group who developed deep venous thrombosis after the operation, and the incidence was 2.50%. The rate was significantly lower than that of the control group (p<0.05). The hip joint function score of the observation group was higher than that of the control group, and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale score was lower than that of the control group (p<0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group (p<0.05).

CONCLUSIONS

PDCA cycle management plus detailed management in patients with hip replacement surgery yields a favorable clinical outcome, which can effectively prevent postoperative deep vein thrombosis, and improve surgical indicators and postoperative coagulation function. Also, it reduces the incidence of adverse reactions in patients and facilitates recovery. It has a beneficial impact on the prognosis of patients and deserves promotion.

Trends and risk factors for readmissions following press-fit total knee arthroplasty for the treatment of end-stage osteoarthritis of the knee: a five-year analysis

INTRODUCTION

The development of new prostheses with improved osseointegration, bone preservation, and reduced cost has renewed interest in uncemented total knee arthroplasty (UCTKA). In the current study, we aimed to: (1) assess demographic data of patients who were and were not readmitted and (2) identify patient-specific risk factors associated with readmission.

METHODS

A retrospective query from the PearlDiver database was performed from January 1, 2015, to October 31, 2020. International Classification of Disease, Ninth Revision (ICD-9), ICD-10, or Current Procedural Terminology (CPT) coding was used to distinguish cohorts of patients who had osteoarthritis of the knee and underwent UCTKA. Patients readmitted within 90 days were classified as the study population, while those who were not readmitted were classified as control. A linear regression model was utilized to analyze readmission risk factors.

RESULTS

The query yielded 14,575 patients, with 986 (6.8%) being readmitted. Patient demographics such as age (P < 0.0001), sex (P < 0.009), and comorbidity (P < 0.0001) were associated with annual 90-day readmission. Patient-specific risk factors associated with 90-day readmission following press-fit total knee arthroplasty were: arrhythmia (OR: 1.29, 95% CI: 1.11-1.49, P < 0.0005), coagulopathy (OR: 1.36, 95% CI: 1.13-1.63, P < 0.0007), fluid and electrolyte abnormalities (OR: 1.59, 95% CI: 1.38-1.84, P < 0.0001), iron deficiency anemia (OR: 1.49, 95% CI: 1.27-1.73, P < 0.0001), and obesity (OR: 1.37, 95% CI: 1.18-1.60, P < 0.0001).

DISCUSSION

This study demonstrates that patients with comorbidities, such as fluid and electrolyte problems, iron deficiency anemia, and obesity, were at an increased risk of readmission after having an uncemented total knee replacement. The risks of readmission following an uncemented total knee arthroplasty can be discussed with patients who have certain comorbidities by arthroplasty surgeons.
