Lithotomy-related neurovascular complications in the lower limbs after colorectal surgery

Enhanced Recovery After Gender-Affirming Surgery

The adoption of enhanced recovery after surgery (ERAS) protocols in multiple surgical disciplines has revolutionized perioperative care, demonstrating reduced complications and shorter hospital stays across surgical specialties. ERAS protocols have increasingly been incorporated in plastic surgery, yet a notable gap in the literature on ERAS for gender-affirming surgery (GAS) still exists. A scoping review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify studies on ERAS protocols in GAS. The aim of this review was to assess the current status of ERAS adoption in GAS, evaluate its impact on perioperative care, and provide recommendations for future research and clinical practice. While there is an overall scarcity of evidence-based ERAS protocols across GAS, published studies on the application of ERAS in GAS have demonstrated promising early outcomes and illustrate an area for further investigation and innovation in plastic surgery.

Well-leg compartment syndrome after laparoscopic low anterior resection in the lithotomy position: a case report and literature review

Well-leg compartment syndrome (WLCS) develops in healthy lower limbs because of surgical factors such as operative position, lower limb compression, and long operative time during abdominopelvic surgery. WLCS can lead to irreversible muscle and nerve damage if a prompt diagnosis and appropriate treatment are not provided. We report the case of a 57-year-old male who developed rectal cancer immediately after laparoscopic low anterior resection and was successfully treated with fasciotomy without sequelae. Patients who undergo surgery in the lithotomy position for a prolonged period are at risk of WLCS. Therefore, when determining the differential diagnosis of postoperative lower leg pain, it is necessary to consider WLCS because it is a complication caused by the intraoperative position.

A Randomized Controlled Comparative Study of the Three Over-Bed Techniques for Positioning and Repositioning the Lithotomy Position While Using Stirrups

Objective

In this study, the clinical application and efficacy of three different methods for placing and repositioning patients in the lithotomy position over the bed using stirrups were evaluated.

Methods

A total of 240 surgical patients who underwent surgery in Chongqing Traditional Chinese Medicine Hospital between July and November 2022 were selected as study participants. Using envelopes, they were randomly divided into three groups of 80 cases each using a randomization method. The groups included the traditional over-bed method, the postural trolley-assisted over-bed method, and the direct over-bed method. Using the Kruskal-Wallis rank-sum test, analysis of variance, and multiple linear regression equations, the placement time, over-bed repositioning time, and total time of the three methods for placing and repositioning in the lithotomy position supported by stirrups were analyzed statistically. In addition, we investigated and examined the satisfaction of nurses and doctors with the aforementioned techniques.

Results

The placement time, repositioning time, and total time were significantly higher for the traditional over-bed method than for the postural trolley-assisted over-bed method and the direct over-bed method (both P < 0.01). However, there was no statistically significant difference between the postural trolley-assisted over-bed method and the direct over-bed method (P > 0.05). Nurses and doctors reported significantly higher satisfaction with the postural trolley-assisted over-bed method and the direct over-bed method compared to the traditional over-bed method (both P < 0.01). In addition, nurses were more satisfied with the direct over-bed method than the postural trolley-assisted over-bed method (P < 0.05).

Conclusion

The results of this study demonstrate that the direct over-bed method is preferred for positioning and repositioning patients in the lithotomy position with the support of stirrups.

Open Sciatic Nerve Decompression for Compartment Syndrome after Prolonged Lithotomy Position: A Case Report

Background: Position-related compressive nerve injury is a frequently reported complication of the lithotomy position. In contrast, compartment syndrome-induced neuropathy after lithotomy with prolonged surgery is rare and prone to misdiagnosis. This case describes the successful open decompression of sciatic neuropathy due to compartment syndrome after a prolonged lithotomy position. Case presentation: A 56-year-old male patient complained of an abnormal sensation in the lower leg and difficulty in dorsiflexion and plantarflexion of the left foot and toes after laparoscopic anterior hepatic sectionectomy for 16 h in a lithotomy position. Physical examination revealed severe pain and paresthesia below the distal left thigh. In manual muscle test grading, dorsiflexion and plantarflexion of the left ankle and toes were classified as grade 1. Computed tomography and magnetic resonance imaging showed ischemic changes in the mid-thigh posterior muscles, and the sciatic nerve was severely swollen at the distal thigh, which was compressed by the proximal edge of the well-leg holder. After debridement of the necrotic tissue and decompression of the sciatic nerve, the pain subsided immediately, and the ankle and toe dorsiflexion motor function improved to grade 4. Conclusions: Most case reports of compressive neuropathy associated with the lithotomy position have been related to conservative treatment. However, if a lesion compressing the nerve is confirmed in an imaging study and the correlation with the patient's symptoms is evident, early surgical intervention can be an effective treatment method to minimize neurological deficits.

Intraoperative pressure monitoring of the lower leg for preventing compression-related complications associated with the lithotomy position

BACKGROUND

Several serious complications are associated with the lithotomy position, including well-leg compartment syndrome and peroneal nerve paralysis. The aims of this study were to identify risk factors for the intraoperative elevation of lower leg pressure and to evaluate the effectiveness of monitoring external pressure during surgery for preventing these complications.

METHODS

The study included 106 patients with a diagnosis of sigmoid colon or rectal cancer who underwent elective laparoscopic surgery between June 2019 and December 2020. We divided the posterior side of the lower leg into four parts (upper outside, upper inside, lower outside, lower inside) and recorded the peak pressure applied to each area at hourly intervals during surgery (called "regular points") and when the operating position was changed (e.g., by head-tilt or leg elevation; called "points after change in position"). When the pressure was observed to be higher than 50 mmHg, we adjusted the position of the leg and re-recorded the data. Data on postoperative leg-associated complications were also collected.

RESULTS

The pressure was measured at a total of 1125 points (regular, n = 620; after change of position, n = 505). The external pressure on the upper outer side of the right leg (median, 36 mmHg) was higher than that on any other area of the lower leg. The pressure increase to more than 50 mmHg was observed not only during the change of position (27.5%) but also during regular points (22.4%). Bodyweight, strong leg elevation, and low head position were identified as factors associated with increased external pressure. There have been no compression-related complications in 534 cases at our institution since the introduction of intraoperative pressure monitoring.

CONCLUSIONS

Several risk factors associated with increased external pressure on the lower leg were identified. Intraoperative pressure monitoring might help reduction of pressure-related complications, needing further and larger prospective data collections.

Creatine kinase elevation after robotic surgery for rectal cancer due to a prolonged lithotomy position

Background

Robotic surgery for rectal cancer, which is now performed worldwide, can be associated with elevated creatine kinase levels postoperatively. In this study, we compared postoperative complications between patients undergoing robotic surgery and laparoscopic surgery.

Methods

We identified 66 consecutive patients who underwent curative resection for rectal cancer at Juntendo University Hospital between January 2016 and February 2019. Patients were divided into a conventional laparoscopic surgery (CLS) group (n = 38) and a robotic-assisted laparoscopic surgery (RALS) group (n = 28) before comparing various clinicodemographic factors between the groups.

Results

Patient age and gender, surgical approach (CLS/RALS), pathological T factor, pathological stage, duration of postoperative hospital stay, and postoperative complications were not significantly different between the RALS and CLS groups. However, the operation time was significantly longer in the RALS group (407 min) than in the CLS group (295 min; p < 0.001). Notably, the serum level of creatine kinase on postoperative day 1 was significantly higher in the CLS group (154 IU/L) than in the RALS group (525 IU/L; p < 0.001), despite there being no significant differences in the incidence of rhabdomyolysis. The multivariate analysis showed that RALS/CLS (HR 6.0 95% CI 1.3–27.5, p = 0.02) and operation time (HR 15.9 95% CI 3.79–67.4, p = 0.001) remained independent factors of CK elevation on postoperative day 1.

Conclusions

Clinically relevant positioning injuries and rhabdomyolysis may occur in patients who are subjected to a prolonged and extreme Trendelenburg position or who have extra force applied to the abdominal wall because of remote center displacement. The creatine kinase value should therefore be measured after RALS to monitor for the sequelae of these potential positioning injuries.

Well-Leg Rhabdomyolysis After Prolonged Knee Arthroscopy: A Case Report

CASE

We present the case of an obese patient who underwent combined arthroscopic and open multiligamentous knee reconstruction who, 3 months later, required revision arthroscopic anterior cruciate ligament and posterior cruciate ligament reconstruction with open lateral collateral ligament and posterolateral corner reconstruction lasting 6 hours 30 minutes. The patient developed rhabdomyolysis of the nonoperative leg after the revision procedure. Both procedures were performed in a hemilithotomy position with a commonly used leg positioner.

CONCLUSIONS

Complications secondary to patient positioning are a source of unnecessary patient morbidity. Surgeons should be mindful of the nonoperative extremity, particularly during prolonged cases in obese patients. Prompt diagnosis and multidisciplinary treatment can lead to the resolution of symptoms without long-term sequelae.

A systematic review of mechanical thromboprophylaxis in the lithotomy position

BACKGROUND

Venous thrombosis and compartment syndrome are potentially serious complications of prolonged, lithotomy position surgery. It is unclear whether mechanical thromboprophylaxis in this group of patients modifies the risk of compartment syndrome. This qualitative systematic review examines the evidence base to guide clinical practice.

METHOD

A systematic review was performed guided by Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) criteria, to identify studies reporting relationships between lithotomy position, compartment syndrome and mechanical thromboprophylaxis. The aim was to determine if mechanical thromboprophylaxis influenced compartment syndrome risk in the lithotomy position.

RESULTS

Sixteen studies were identified: eight case reports or case series (12 patients), two completed audit cycles (approximately 2000 patients), four reviews and two volunteer case control studies (33 subjects). There were no randomised studies. Nine studies associated mechanical thromboprophylaxis with compartment syndrome risk but in each case a causative relationship was speculative. In contrast, five papers, including an experimental, cohort study and two observational, population studies recommended intermittent pneumatic compression as prevention against compartment syndrome in lithotomy position. One review and one case report were unable to make a recommendation.

CONCLUSIONS

The level of evidence addressing the interaction between the lithotomy position, compartment syndrome and mechanical thromboprophylaxis is weak. There is no conclusive evidence that mechanical thromboprophylaxis causes compartment syndrome in the lithotomy position. There is limited evidence to suggest intermittent pneumatic compression may be a safe method of mechanical thromboprophylaxis if accompanied by strict adherence to other measures to reduce the chance of compartment syndrome. However further studies are required.

Well-leg compartment syndrome after laparoscopic low anterior resection for lower rectal cancer in the lithotomy position: A case report

A 64-year-old man underwent laparoscopic low anterior resection for lower rectal cancer. Because he was overweight (BMI, 28.1 kg/m² ) with rich visceral fat and a narrow pelvic cavity, the operation was technically difficult and the operation time was 686 min. Postoperatively, the patient immediately complained of pain and swelling of the left lower limb. Laboratory examination showed that serum creatinine kinase was markedly increased and urine myoglobin was positive on postoperative day 1. He was diagnosed with well-leg compartment syndrome and was transported to the trauma and critical care center for emergency fasciotomy. After initial treatment, he was transferred to our hospital on postoperative day 7. He completely recovered after 2 months. Although well-leg compartment syndrome is rare, it is necessary to consider it as a potential complication when performing a long colorectal cancer surgery with the patient in the lithotomy position, particularly when laparoscopic surgery is planned.

Incidence, Risk Factors, and Trends of Motor Peripheral Nerve Injury After Colorectal Surgery: Analysis of the National Surgical Quality Improvement Program Database

BACKGROUND

Motor peripheral nerve injury is a rare but serious event after colorectal surgery, and a nationwide study of this complication is lacking.

OBJECTIVE

The purpose of this study was to report the incidence, trends, and risk factors of motor peripheral nerve injury during colorectal surgery.

DESIGN

The National Surgical Quality Improvement Program database was surveyed for motor peripheral nerve injury complicating colorectal procedures. Risk factors for this complication were identified using logistic regression analysis.

SETTINGS

The study used a national database.

PATIENTS

Patients undergoing colorectal resection between 2005 and 2013 were included.

MAIN OUTCOME MEASURES

The incidence, trends, and risk factors for motor peripheral nerve injury complicating colorectal procedures were measured.

RESULTS

We identified 186,936 colorectal cases, of which 50,470 (27%) were performed laparoscopically. Motor peripheral nerve injury occurred in 122 patients (0.065%). Injury rates declined over the study period, from 0.025% in 2006 to <0.010% in 2013 (p < 0.001). Patients with motor peripheral nerve injury were younger (mean ± SD; 54.02 ± 15.41 y vs 61.56 ± 15.95 y; p < 0.001), more likely to be obese (BMI ≥30; 43% vs 31%; p = 0.003), and more likely to have received radiotherapy (12.3% vs 4.7%; p < 0.001). Nerve injury was also associated with longer operative times (277.16 ± 169.79 min vs 176.69 ± 104.80 min; p < 0.001) and was less likely to be associated with laparoscopy (p = 0.043). Multivariate analysis revealed that increasing operative time was associated with nerve injury (OR = 1.04 (95% CI, 1.03-1.04)), whereas increasing age was associated with a protective effect (OR = 0.80 (95% CI, 0.71-0.90)).

LIMITATIONS

This study was limited by its retrospective nature.

CONCLUSIONS

Motor peripheral nerve injury during colorectal procedures is uncommon (0.065%), and its rate declined significantly over the study period. Prolonged operative time is the strongest predictor of motor peripheral nerve injury during colorectal procedures. Instituting and documenting measures to prevent nerve injury is imperative; however, special attention to this complication is necessary when surgeons contemplate long colorectal procedures.

Well leg compartment syndrome after surgery for ulcerative colitis in the lithotomy position: A case report

INTRODUCTION

Well leg compartment syndrome (WLCS) is an uncommon and severe complication that occurs after colorectal surgery in the lithotomy position.

PRESENTATION OF CASE

The current patient was a 28-year-old male suffering from ulcerative colitis. He was underwent elective proctectomy, including ileal J pouch formation and anal anastomosis with temporary loop ileostomy. The ileoanal pouch procedure was quite difficult, and during this procedure, the high lithotomy and head down tilt positions were continued for 255min. After the operation, the patient complained of severe cramping pain, swelling and serious tenderness on palpation in both legs. On the first postoperative day, the patient's complaints gradually worsened. The intra-compartmental pressure was measured, and WLCS was diagnosed. Emergency bilateral fasciotomy was performed. Initially, the patient had a sensory deficit and analgesia, however, his sensory disturbance and pain had almost recovered two months after fasciotomy by rehabilitation.

DISCUSSION

In the current case, the important factors associated with the development of WLCS are thought to be a prolonged operative time in which the patient is placed in the high lithotomy position during ileoanal pouch procedure.

CONCLUSION

We would thus like to emphasize that operations for the ileoanal pouch procedure to treat ulcerative colitis have a high potential for inducing WLCS, because it usually requires a prolonged operative time in which the patient remains in the high lithotomy position.

Method of Breast Reconstruction Determines Venous Thromboembolism Risk Better Than Current Prediction Models

Background:

Venous thromboembolism (VTE) risk models including the Davison risk score and the 2005 Caprini risk assessment model have been validated in plastic surgery patients. However, their utility and predictive value in breast reconstruction has not been well described. We sought to determine the utility of current VTE risk models in this population and the VTE rate observed in various methods of breast reconstruction.

Methods:

A retrospective review of breast reconstructions by a single surgeon was performed. One hundred consecutive transverse rectus abdominis myocutaneous (TRAM) patients, 100 consecutive implant patients, and 100 consecutive latissimus dorsi patients were identified over a 10-year period. Patient demographics and presence of symptomatic VTE were collected. 2005 Caprini risk scores and Davison risk scores were calculated for each patient.

Results:

The TRAM reconstruction group was found to have a higher VTE rate (6%) than the implant (0%) and latissimus (0%) reconstruction groups (P < 0.01). Mean Davison risk scores and 2005 Caprini scores were similar across all reconstruction groups (P > 0.1). The vast majority of patients were stratified as high risk (87.3%) by the VTE risk models. However, only TRAM reconstruction patients demonstrated significant VTE risk.

Conclusions:

TRAM reconstruction appears to have a significantly higher risk of VTE than both implant and latissimus reconstruction. Current risk models do not effectively stratify breast reconstruction patients at risk for VTE. The method of breast reconstruction appears to have a significant role in patients’ VTE risk.

Leg Pain and Gynecologic Malignancy

Gynecologic malignancies affect more than 83 000 women in the United States, each year. Because the disease involves the pelvis, many patients have side effects distal to this area in their lower extremities. The differential diagnosis of leg pain can be divided into vascular, neurologic, and musculoskeletal causes. In this review article, we address numerous etiologies of leg pain, reviewing the prevalence of disease, physical examination findings, diagnostic as well as treatment modalities.

Unicompartment compartment syndrome following laparascopic colonic resection

We report the case of a 43-year-old man who developed anterior compartment syndrome following laparoscopic colorectal surgery in the lithotomy position. This was initially masked by postoperative epidural usage and ultimately diagnosed 2 days postoperatively. The patient underwent decompression by four compartment fasciotomy and two follow-up re-explorations of the affected lower limb. This case is unique for two reasons: only the anterior compartment of the lower limb was affected--which is rare in itself--and there was a delay in presentation secondary to postoperative epidural usage.

Pitfalls of laparoscopic colorectal surgery and how to avoid them

SUMMARY Laparoscopic surgery is commonly used for colorectal diseases. Recently, laparoscopy for colorectal carcinoma has increased in use, especially by colorectal surgeons. Laparoscopy is associated with potential pitfalls that pose challenges to the surgeon and team. The identification and management of these pitfalls may not directly parallel those during an open approach. As such, it is essential for the surgeon to have a good working knowledge of how to avoid potential problems and how to best manage them when they do occur. This review highlights common pitfalls of laparoscopic colorectal surgery, as well as offering practical approaches to their management. Technical, patient and surgeon factors are all discussed.

A systematic review of peripheral nerve injury following laparoscopic colorectal surgery

AIM

The risk of peripheral nerve injury associated with laparoscopic colorectal surgery has not been well established. We aimed to identify the number and type of peripheral nerve injuries associated with patient positioning in laparoscopic surgery.

METHOD

A systematic review of MEDLINE and Embase was undertaken of English and non-English language articles. Search terms included the key words: laparoscopic, colorectal, nerve injury, nerve damage, brachial plexus, peripheral neuropathy, peripheral nerve injury, nerve and colonic injury. Articles were included where at least one peripheral nerve injury had been documented related to patient positioning at laparoscopic colorectal surgery. Data extraction for articles was conducted by two authors, using predefined data fields.

RESULTS

Ten cases have been reported in the literature. All injuries involved the brachial plexus. They were associated with a lengthy procedure and abduction of the arm.

CONCLUSION

Although rare, the surgeon and theatre team must be aware of the risk of peripheral nerve injury when positioning patients for laparoscopic colorectal procedures.
