Antimicrobial Prophylaxis Reduces the Rate of Surgical Site Infection in Upper Gastrointestinal Surgery: A Systematic Review

Maximizing oral intake tolerance in malignant gastric outlet obstruction - a Markov decision tree analysis comparing duodenal stenting, endoscopic ultrasound-guided gastroenterostomy and surgical gastrojejunostomy based on a meta-analysis of randomized controlled trials

INTRODUCTION

Malignant gastric outlet obstruction (GOO) has a significant impact on quality of life. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) has shown promising results. Traditional isolated outcome measures do not sufficiently address critical considerations for end-of-life patients like oral intake tolerance. This study aimed to determine via a probabilistic approach, the optimal management strategy for GOO patients that maximizes their oral intake tolerance.

METHODS

A Markov decision model was developed, with input variables based on a systematic review and meta-analysis of randomized controlled trials (RCT) comparing duodenal stenting (DS), EUS-GE and surgical gastrojejunostomy (GJ). A prospective cohort study with a comparator group was also included for EUS-GE model given the scarcity of RCTs. Model assumption was a patient with malignant GOO, with equal probabilities of being allocated to 1 of 3 treatment options. Each data point was evaluated using pooled probabilities from the meta-analysis of clinical outcomes. Primary outcome was successful oral intake tolerance at various time points of 1-6 months post-intervention.

RESULTS

Fifteen studies were included into the Markov model. Based on 10 000 simulations in each arm, at a survival of 1-month, DS and EUS-GE had the highest likelihood of oral intake (81.2% and 80.4%) compared to GJ (75.5%). However, at a survival of 6-month, EUS-GE and GJ were better at palliating GOO, with likelihood of oral intake at 23.8% and 25.2%, compared to 21.3% for DS.

CONCLUSION

For patients with a prognosis of more than 1-month, a surgical GJ, or EUS-GE if technical expertise is available, is preferred for GOO palliation.

Transfusion Thresholds and Risk Factors of Acute Kidney Injury in Gastrointestinal Oncology Surgery: Insights from a Retrospective Study

Objectives: To identify transfusion thresholds and risk factors for acute kidney injury (AKI) in gastrointestinal oncology surgery, enhancing early intervention and improving postoperative outcomes. Methods: From 2018 to 2022, 765 patients with gastric or colorectal cancer who underwent major gastrointestinal surgery were retrospectively enrolled. The primary outcome was AKI development within 7 days postoperatively. Clinicopathological characteristics and short-term outcomes were recorded and compared. Results: Of all enrolled patients, 39 (5.1%) developed AKI. Patients with AKI were predominantly older and had more preoperative comorbidities, lower levels of preoperative hemoglobin and serum albumin, but higher levels of blood urea nitrogen and serum creatinine (SCr). Patients developing AKI experienced higher rates of in-hospital complications (overall: 48.3% vs. 14.2%, p < 0.001), prolonged hospital stays (25.4 ± 22.5 days vs. 12.3 ± 7.9 days, p < 0.001), increased intensive care unit (ICU) admissions (53.8% vs. 22.5%, p < 0.001), and higher rates of 30-day re-admission (13.9% vs. 2.4%, p = 0.003). Significant AKI risk factors included age (per 10 years, OR: 1.567, 95% CI: 1.103-2.423, p = 0.043), preoperative SCr (per 10 μmol/L, OR: 1.173, 95% CI: 1.044-1.319, p = 0.007), intraoperative RBC transfusion (per 1000 mL, OR: 1.992, 95% CI: 1.311-3.027, p = 0.001 with a significant surge in AKI risk at transfusions exceeding 1500 mL), patient-controlled analgesia (protective, OR:0.338, 95% CI: 0.163-0.928, p = 0.033), and diuretic use (OR: 5.495, 95% CI: 1.720-17.557, p = 0.004). Conclusions: Early intervention is essential for patients with preoperative low perfusion or anemia, with particular emphasis on moderating interventions to avoid fluid overload while carefully avoiding nephrotoxic medications, thereby improving postoperative outcomes.

Association of Antibiotic Used During Surgery With the Outcome in Stage I-III Gastric Cancer

Introduction: The use of antibiotic (Abx) is common in gastric cancer (GC) patients undergoing radical resection; however, the prognostic value of the use of these agents in stage I-III patients remains largely unknown.Methods: Data concerning the use of Abx in GC patients during surgery including the cumulative defined daily dose (cDDD) and types of Abx, were collected retrospectively. Differences in clinical features between cDDD subgroups and type subgroups were compared. Overall survival (OS) differences were tested via the Kaplan-Meier method, and risk factors for survival were validated by a Cox proportional hazards model.Results: Of 162 patients enrolled, 81 were assigned to the low-cDDD and 81 to the high-cDDD group. Among them, 19 patients were assigned to ≤2 types and 143 to ≥3 types. The low- and high-cDDD subgroups of patients presented no significant difference in OS (log rank = 2.21, P = 0.137). Patients receiving ≥3 types presented significantly better OS (log rank = 4.58, P = 0.032) than those receiving ≤2 types. The low- and high-cDDD subgroups (log rank = 3.83, P = 0.050), but not the ≤2 and ≥3 type subgroups (log rank<0.01, P = 0.982), presented a significant difference in OS in patients undergoing total gastrectomy. These differences were maintained in patients without total gastrectomy (cDDD: log rank = 7.92, P = 0.005; types: log rank = 6.52, P = 0.011). The use of multiple Abx types was validated as an independent factor for OS (HR = 0.46, 95% CI: 0.24-0.90; P = 0.024).Conclusions: Abx use during surgery in patients with stage I-III GC may potentially correlate with the prognosis. Patients with ≥3 types of Abx were more likely to have good outcomes, particularly in those without total gastrectomy.

Weighing the benefits: Exploring the differential effects of light-weight and heavy-weight polypropylene meshes in inguinal hernia repair in a retrospective cohort study

BACKGROUND

Inguinal hernia repair is a common surgical procedure, with more than 20 million cases yearly. Choice between mesh types varies in clinical practice. To compare light-weight polypropylene (LW-PP, 34-36 g/m2) and heavy-weight polypropylene (HW-PP, 95 ​g/m2) meshes.

METHODS

Data from patients who underwent open inguinal hernia repair between 2020 and 2022. Selection criteria ensured homogeneity. Endpoints were to assess the impact of different mesh weights on overall health-related quality of life (HRQoL), using Short Form 36 (SF-36), and to monitor postoperative complications.

RESULTS

Two hundred patients were included in both groups. Lateral and direct hernias occurred in 60.5 ​% and 39.5 ​%. According to EHS, 31.5 ​%, 22.3 ​% and 46.2 ​% were classified as size 1, 2, 3. Follow-up showed similar HRQoL at 30-days, with a favorable trend towards LW-PP mesh offering fewer limitations, better comfort, and improved general health after 12-months. No difference in postoperative paresthesia, wound hematoma, and interference with daily activities.

CONCLUSION

1-year after surgery HRQoL evaluation highlights the non-inferiority of LW-PP. Mesh selection should be tailored, aiming at improving outcomes and postoperative comfort.

The Aging Stomach: Clinical Implications of H. pylori Infection in Older Adults-Challenges and Strategies for Improved Management

Aging is a multifactorial biological process characterized by a decline in physiological function and increasing susceptibility to various diseases, including malignancies and gastrointestinal disorders. Helicobacter pylori (H. pylori) infection is highly prevalent among older adults, particularly those in institutionalized settings, contributing to conditions such as atrophic gastritis, peptic ulcer disease, and gastric carcinoma. This review examines the intricate interplay between aging, gastrointestinal changes, and H. pylori pathogenesis. The age-associated decline in immune function, known as immunosenescence, exacerbates the challenges of managing H. pylori infection. Comorbidities and polypharmacy further increase the risk of adverse outcomes in older adults. Current clinical guidelines inadequately address the specific needs of the geriatric population, who are disproportionately affected by antibiotic resistance, heightened side effects, and diagnostic complexities. This review focuses on recent advancements in understanding H. pylori infection among older adults, including epidemiology, diagnostics, therapeutic strategies, and age-related gastric changes. Diagnostic approaches must consider the physiological changes that accompany aging, and treatment regimens need to be carefully tailored to balance efficacy and tolerability. Emerging strategies, such as novel eradication regimens and adjunctive probiotic therapies, show promise for improving treatment outcomes. However, significant knowledge gaps persist regarding the impact of aging on H. pylori pathogenesis and treatment efficacy. A multidisciplinary approach involving gastroenterologists, geriatricians, and other specialists is crucial to providing comprehensive care for this vulnerable population. Future research should focus on refining diagnostic and therapeutic protocols to bridge these gaps, ultimately enhancing clinical outcomes and reducing the burden of H. pylori-associated diseases in the aging population.

Extraperitoneal Open Radical Cystectomy: A New Standard in Frail Patients with Muscle-Invasive Bladder Cancer?

Background/Objectives: Radical cystectomy (RC) represents one of the most complex and morbid surgical procedures in the field of Urology. Extraperitoneal open RC has emerged as an alternative to the traditional transperitoneal approach for the treatment of muscle-invasive bladder cancer. Frailty is one of the most important risk factors for perioperative morbidity and mortality, and this category of patients can benefit the most from the extraperitoneal approach. The purpose of this study was to evaluate the feasibility and the safety of extraperitoneal open RC in our experience; Methods: We retrospectively collected the data of 75 frail patients who underwent an extraperitoneal open RC, performed by a single experienced surgeon. We assessed their frailty status using the simplified frailty index (sFI). We recorded data regarding general characteristics, intraoperative, pathological, and postoperative complications, and mortality (within 90 days); Results: We analyzed 61 males and 14 females with an sFI equal to or higher than 3. The median age was 77 years. Fifty-one patients had an ASA score of 3 or more. Sixty procedures were with radical intention, while fifteen were palliative. Cutaneous ureterostomy was performed in 70 cases and extraperitonized ileal conduit in five cases. The median operative time was 150 min. The median blood loss was 400 mL. The median time to flatus was 2 days. The median postoperative stay was 7 days. Thirteen patients had Clavien-Dindo III or IV complications. Two patients died in first 90 days postoperatively; Conclusions: The extraperitoneal open RC in frail patients was demonstrated to be a feasible and safe alternative approach in definitive treatment or a palliative setting in our experience.

Predictive Value of Preoperative Peripheral Blood Inflammatory Markers for Surgical Site Infection in Laparoscopic Radical Gastrectomy for Gastric Cancer

Background: To investigate the predictive value of preoperative peripheral blood inflammatory markers for surgical site infection (SSI) in laparoscopic radical gastrectomy for gastric cancer. Methods: A retrospective analysis was conducted on patients undergoing laparoscopic radical gastrectomy for gastric cancer, categorized into SSI and non-SSI groups based on postoperative SSI occurrences. Patient demographics, surgical details, laboratory results, and SSI incidence data were extracted. Differences in indicators, including neutrophil-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), and platelet-lymphocyte ratio (PLR), were assessed between the two groups. Multivariate logistic regression was utilized to determine the independent association of each indicator with SSI. Receiver operating characteristics (ROC) curve analysis was utilized to evaluate the predictive value of parameters. Results: Of 169 patients, 36 (21.30%) experienced SSI postoperatively. The SSI group exhibited higher preoperative NLR and SII (p < 0.05). After adjusting for variables, preoperative NLR (OR = 1.691, 95% CI: 1.211-2.417, p = 0.003) and SII (OR = 1.001, 95% CI: 1.000-1.002, p = 0.006) were identified as independent risk factors for SSI. Both NLR (AUC = 0.758, 95% CI: 0.666-0.850) and SII (AUC = 0.753, 95% CI: 0.660-0.850) demonstrated favorable diagnostic performance for predicting postoperative SSI. Conclusion: Preoperative NLR and SII significantly associate with postoperative SSI in laparoscopic radical gastrectomy for gastric cancer, making them valuable indicators for early prediction of SSI.

Cefotaxime Versus Ceftriaxone: A Comprehensive Comparative Review

Cefotaxime and ceftriaxone are two prominent third-generation cephalosporin antibiotics, which are a class of antimicrobial agents with overlapping antibacterial spectra and therapeutic indications, commonly used in treating severe bacterial infections, including meningitis, sepsis, and respiratory tract infections. Despite their shared antibacterial coverage, these antibiotics differ significantly in their pharmacokinetic characteristics such as half-life, protein binding, and tissue penetration. This comprehensive review systematically compares the pharmacokinetic profiles, pharmacological attributes, clinical efficacy, and safety profiles of cefotaxime and ceftriaxone. It further highlights the importance of understanding the nuanced differences between cefotaxime and ceftriaxone, particularly in clinical settings such as intensive care units or during pediatric treatment, where rapid bactericidal action or prolonged drug activity might influence therapeutic outcomes. While their overlapping spectrums offer versatility, clinicians should consider these distinct pharmacokinetic attributes and associated clinical outcomes to guide optimal antibiotic selection.

Identification of predictive factors for surgical site infections in gastrointestinal surgeries: A retrospective cross-sectional study in a resource-limited setting

Background

Surgical site infection (SSI), albeit infrequent, drastically impacts the quality of care. This article endeavors to investigate the predictive factors of SSIs following surgical interventions that involve the gastrointestinal (GI) tract within a single institution in a resource-limited setting.

Methods

Over seven years from June 2015 to June 2022, patients who underwent GI surgery and developed SSI were retrospectively matched with an unaffected case-control cohort of patients. Standardized techniques for wound culture, laboratory evaluation of bacterial isolates, and antibiotic susceptibility tests were employed. Logistic regression analysis was utilized to investigate the predictive factors associated with 30-day postoperative SSI occurrence.

Results

A total of 525 patients who underwent GI surgical procedures were included, among whom, 86 (16.4%) developed SSI and the majority of SSIs were superficial (74.4%). Escherichia coli was the most commonly isolated bacterium (54.4%), and a high percentage of multidrug-resistant organisms were observed (63.8%). In multivariate Cox regression analysis, illiteracy (Odds ratio [OR]:40.31; 95% confidence interval [CI]: 9.54-170.26), smoking (OR: 21.15; 95% CI: 4.63-96.67), diabetes (OR: 5.07; 95% CI: 2.27-11.35), leukocytosis (OR: 2.62; 95% CI: 1.24-5.53), hypoalbuminemia (OR: 3.70; 95% CI: 1.35-10.16), contaminated and dirty wounds (OR: 6.51; 95% CI:1.62-26.09), longer operation duration (OR: 1.02; 95% CI: 1.01-1.03), emergency operations (OR: 12.58; 95% CI: 2.91-54.30), and extending antibiotic prophylaxis duration (OR: 3.01; 95% CI: 1.28-7.10) were the independent risk factors for SSI (all p < 0.05).

Conclusions

This study highlights significant predictors of SSI, including illiteracy, smoking, diabetes, leukocytosis, hypoalbuminemia, contaminated and dirty wounds, longer operative time, emergency operations, and extending antibiotic prophylaxis duration. Identifying these risk factors can help surgeons adopt appropriate measures to reduce postoperative SSI and improve the quality of surgical care, especially in a resource-limited setting with no obvious and strict policy for reducing SSI.

Emergency and Elective Colorectal Cancer-Relationship between Clinical Factors, Tumor Topography and Surgical Strategies: A Cohort Study

Background and Objectives: The purpose of the study was to analyze the relationships among several clinical factors and also the tumor topography and surgical strategies used in patients with colorectal cancer. Materials and Methods: We designed an analytical, observational, retrospective study that included patients admitted to our emergency surgical department and diagnosed with colorectal cancer. The study group inclusion criteria were: patients admitted during 2020-2022; patients diagnosed with colorectal cancer (including the ileocecal valve); patients who benefited from a surgical procedure, either emergency or elective. Results: In our study group, consisting of 153 patients, we accounted for 56.9% male patients and 43.1% female patients. The most common clinical manifestations were pain (73.2% of the study group), followed by abdominal distension (69.3% of the study group) and absence of intestinal transit (38.6% of the study group). A total of 69 patients had emergency surgery (45.1%), while 84 patients (54.9%) benefited from elective surgery. The most frequent topography of the tumor was the sigmoid colon, with 19.60% of the patients, followed by the colorectal junction, with 15.68% of the patients, and superior rectum and inferior rectum, with 11.11% of the patients in each subcategory. The most frequent type of procedure was right hemicolectomy (21.6% of the study group), followed by rectosigmoid resection (20.9% of the study group). The surgical procedure was finished by performing an anastomosis in 49% of the patients, and an ostomy in 43.1% of the patients, while for 7.8% of the patients, a tumoral biopsy was performed. Conclusions: Colorectal cancer remains one of the most frequent cancers in the world, with a heavy burden that involves high mortality, alterations in the quality of life of patients and their families, and also the financial costs of the medical systems.

Antimicrobial Prophylaxis With Ampicillin-sulbactam Compared With Cefazolin for Esophagectomy: Nationwide Inpatient Database Study in Japan

OBJECTIVE

To assess the effect of antimicrobial prophylaxis with ampicillin-sulbactam (ABPC/SBT) compared with cefazolin (CEZ) on the short-term outcomes after esophagectomy.

BACKGROUND

CEZ is widely used for antimicrobial prophylaxis in esophagectomy without procedure-specific evidence, whereas ABPC/SBT is preferred in some hospitals to target both aerobic and anaerobic oral bacteria.

METHODS

Data of patients who underwent esophagectomy for cancer between July 2010 and March 2019 were extracted from a nationwide Japanese inpatient database. Overlap propensity score weighting was conducted to compare the short-term outcomes [including surgical site infection (SSI), anastomotic leakage, and respiratory failure] between antimicrobial prophylaxis with CEZ and ABPC/SBT after adjusting for potential confounders. Sensitivity analyses were also performed using propensity score matching and instrumental variable analyses.

RESULTS

Among 17,772 eligible patients, 16,077 (90.5%) and 1695 (9.5%) patients were administered CEZ and ABPC/SBT, respectively. SSI, anastomotic leakage, and respiratory failure occurred in 2971 (16.7%), 2604 (14.7%), and 2754 patients (15.5%), respectively. After overlap weighting, ABPC/SBT was significantly associated with a reduction in SSI [odds ratio 0.51 (95% CI: 0.43-0.60)], anastomotic leakage [0.51 (0.43-0.61)], and respiratory failure [0.66 (0.57-0.77)]. ABPC/SBT was also associated with reduced respiratory complications, postoperative length of stay, and total hospitalization costs. The proportion of Clostridioides difficile colitis and noninfectious complications did not differ between the groups. Propensity score matching and instrumental variable analyses demonstrated equivalent results.

CONCLUSIONS

The administration of ABPC/SBT as antimicrobial prophylaxis for esophagectomy was associated with better short-term postoperative outcomes compared with CEZ.

Clinical and economic comparison of laparoscopic versus open hepatectomy for primary hepatolithiasis: a propensity score-matched cohort study

BACKGROUND

It is unclear whether laparoscopic hepatectomy (LH) for hepatolithiasis confers better clinical benefit and lower hospital costs than open hepatectomy (OH). This study aim to evaluate the clinical and economic value of LH versus OH.

METHODS

Patients undergoing OH or LH for primary hepatolithiasis at Yijishan Hospital of Wannan Medical College between 2015 and 2022 were divided into OH group and LH group. Propensity score matching (PSM) was used to balance the baseline data. Deviation-based cost modelling and weighted average median cost (WAMC) were used to assess and compare the economic value.

RESULTS

A total of 853 patients were identified. After exclusions, 403 patients with primary hepatolithiasis underwent anatomical hepatectomy (OH n=143; LH n=260). PSM resulted in 2 groups of 100 patients each. Although LH required a longer median operation duration compared with OH (285.0 versus 240.0 min, respectively, P<0.001), LH patients had fewer wound infections, fewer pre-discharge overall complications (26 versus 43%, respectively, P=0.009), and shorter median postoperative hospital stays (8.0 versus 12.0 days, respectively, P<0.001). No differences were found in blood loss, major complications, stone clearance, and mortality between the two matched groups. However, the median overall hospital cost of LH was significantly higher than that of OH (CNY¥52,196.1 versus 45,349.5, respectively, P=0.007). Although LH patients had shorter median postoperative hospital stays and fewer complications than OH patients, the WAMC was still higher for the LH group than for the OH group with an increase of CNY¥9,755.2 per patient undergoing LH.

CONCLUSION

The overall clinical benefit of LH for hepatolithiasis is comparable or even superior to that of OH, but with an economic disadvantage. There is a need to effectively reduce the hospital costs of LH and the gap between costs and diagnosis-related group reimbursement to promote its adoption.

Effect of Fish Oil Parenteral Emulsion Supplementation on Inflammatory Parameters after Esophagectomy

(Background) Esophagectomy (EPG) presents high morbidity and mortality. Omega-3 fatty acids (ω-3FA) are a pharmaconutrient with benefits for postoperative morbidity. Studies of ω-3FA administered parenterally after esophagectomy are scarce. This study proposes to investigate the effect of combining fish oil lipid emulsions (LE) administered parenterally with enteral nutrition support. (Methods) Randomization was 1:1:1 in three groups: Group A received a LE mixture of 0.4 g/kg/day of fish oil and 0.4 g/kg/day of LCT/MCT 50:50, Group B received 0.8 g/kg/day of fish oil LE, and Group C received 0.8 g/kg/day of LCT/MCT 50:50. Variables were measured at recruitment time and day +1, +3, and +5. Inflammatory variables studied were Interlukin-6, C-reactive protein (CRP), tumoral necrosis factor-α (TNF-α), IL-10, IL-8 and CD25s. Safety, nutritional parameters and complications were analyzed. (Results) Administration of ω-3LE in the immediate postoperative period did not modulate the earlier inflammatory response. Statistically significant differences were found in IL-6 and CRP overall temporal evolution but were not found when studying the type of LE administered or in patients needing critical care. Administration of ω-3 resulted in safe and improved hypertriglyceridemia, depending on the dose. (Conclusions) ω-3FA has no impact on the early inflammatory postoperative response assessed for a short period but was safe. More studies for longer periods are needed.

The efficacy of wound edge protectors in reducing the post-operative surgical site infections after abdominal surgery: a meta-analysis of randomized clinical studies

Introduction

Following abdominal surgery, surgical site infections (SSIs) are a common complication. The effectiveness of wound edge protectors in preventing SSI remains uncertain.

Aim

To determine the clinical effectiveness of a wound edge protector (WEP) in preventing surgical site infections (SSIs) after abdominal surgery.

Material and methods

A systematic search of the Cochrane Library, PubMed, Embase, and Web of Science yielded all relevant articles published through October 2022. The major evidence regarding the efficacy of WEPs in minimizing SSIs in abdominal surgery patients relative to the standard of care was determined by searching the literature. The primary outcome was SSI as clinically defined by CDC. To combine qualitative factors, risk ratios (RRs) were used.

Results

WEPs were related to a decreased incidence of SSI overall (RR = 0.75; 95% CI: 0.61-0.91; p = 0.004). WEPs are efficient in lowering the incidence of SSI at various abdominal surgical sites, with RR = 0.67; 95% CI: 0.47-0.96; p = 0.03 for pancreatoduodenectomy, RR = 0.52; 95% CI: 0.31-0.86; p = 0.01 for colorectal surgery, and RR = 0.39; 95% CI: 0.21-0.73; p = 0.003 for abdominal surgery. Moreover, both kinds of WEPs (single-ring and double-ring devices) were successful in lowering the risk of SSIs, with RR = 0.66; 95% CI: 0.47-0.93; p = 0.02 for double-ring devices and RR = 0.76; 95% CI: 0.58-0.98; p = 0.04 for single-ring devices.

Conclusions

These findings demonstrate that double- and single-ring wound edge protection devices are effective in preventing surgical site infections following pancreatoduodenectomy, colorectal, and abdominal procedures.

Gastrointestinal stromal tumour: presenting as an ovarian cystadenoma

A gastrointestinal stromal tumortumour (GIST) is an uncommon gastrointestinal neoplasm that can arise from any part of the gastrointestinal tract. They can rarely present as a pelvic mass, which might result in a gynaecological condition being misdiagnosed in a female patient. A woman in her early 70s presented with a huge pelvic mass. Abdomen-pelvis CT scan showed a significant cystic mass in the left-sided pelvis with a mass effect on adjacent structures, which suggested a possibility of an ovarian cystadenoma. Her CA-125 was normal. She underwent an exploratory laparotomy with pelvic mass excision. A diagnosis of a gastrointestinal stromal tumour (GIST) arising from the ileum was made on a histopathology study.

Assessment of safety during hospitalization for patients undergoing Surgery after neoadjuvant therapy for moderately advanced Esophageal cancer

PURPOSE

To study the safety of patients with moderately advanced esophageal cancer during their hospital stay after undergoing surgery.

METHODS

The clinical and pathological data of 66 patients with locally advanced esophageal cancer discharged from the Department of Thoracic Surgery of Jiangsu University Hospital from January 2017 to October 2022 were selected, of whom 32 underwent direct surgery (control group) and 34 underwent neoadjuvant therapy followed by surgery (experimental group), to retrospectively analyze whether there were differences in surgical outcomes, complication rates, biochemical and infection indicators between the two groups.

RESULTS

The number of lymph node dissections, lymph node dissection rate, and hemoglobin value on the first day after the operation in the experimental group were smaller than those in the control group, and the difference was statistically significant (P < 0.05). The thoracic drainage volume of the experimental group was more than that of the control group, and the difference was statistically significant (P < 0.05). The incidence of pulmonary complications in the experimental group was higher than that in the control group, especially pulmonary infection, and the difference was statistically significant (P < 0.05). Compared with the control group, the experimental group was more prone to anastomotic leakage, and the difference was statistically significant (P < 0.05).

CONCLUSION

Neoadjuvant therapy combined with surgery for patients with advanced esophageal cancer is generally safe during hospitalization.

Knowledge and awareness of infection control practices among nursing professionals: A cross-sectional survey from South Asia and the Middle East

BACKGROUND

The proficiency of nursing professionals in the infection prevention and control (IPC) practices is a core component of the strategy to mitigate the challenge of healthcare associated infections.

AIM

To test knowledge of nurses working in intensive care units (ICU) in South Asia and Middle East countries on IPC practices.

METHODS

An online self-assessment questionnaire based on various aspects of IPC practices was conducted among nurses over three weeks.

RESULTS

A total of 1333 nurses from 13 countries completed the survey. The average score was 72.8% and 36% of nurses were proficient (mean score > 80%). 43% and 68.3% of respondents were from government and teaching hospitals, respectively. 79.2% of respondents worked in < 25 bedded ICUs and 46.5% in closed ICUs. Statistically, a significant association was found between the knowledge and expertise of nurses, the country's per-capita income, type of hospitals, accreditation and teaching status of hospitals and type of ICUs. Working in high- and upper-middle-income countries (β = 4.89, 95%CI: 3.55 to 6.22) was positively associated, and the teaching status of the hospital (β = -4.58, 95%CI: -6.81 to -2.36) was negatively associated with the knowledge score among respondents.

CONCLUSION

There is considerable variation in knowledge among nurses working in ICU. Factors like income status of countries, public vs private and teaching status of hospitals and experience are independently associated with nurses' knowledge of IPC practices.

The Role of Hyperbaric Oxygen Therapy in the Treatment of Surgical Site Infections: A Narrative Review

Surgical site infections (SSIs) are among the most prevalent postoperative complications, with significant morbidity and mortality worldwide. In the past half century, hyperbaric oxygen therapy (HBOT), the administration of 100% oxygen intermittently under a certain pressure, has been used as either a primary or alternative therapy for the management or treatment of chronic wounds and infections. This narrative review aims to gather information and evidence supporting the role of HBOT in the treatment of SSIs. We followed the Scale for the Quality Assessment of Narrative Review Articles (SANRA) guidelines and scrutinized the most relevant studies identified in Medline (via PubMed), Scopus, and Web of Science. Our review indicated that HBOT can result in rapid healing and epithelialization of various wounds and has potential beneficial effects in the treatment of SSIs or other similar infections following cardiac, neuromuscular scoliosis, coronary artery bypass, and urogenital surgeries. Moreover, it was a safe therapeutic procedure in most cases. The mechanisms related to the antimicrobial activity of HBOT include direct bactericidal effects through the formation of reactive oxygen species (ROS), the immunomodulatory effect of HBOT that increase the antimicrobial effects of the immune system, and the synergistic effects of HBOT with antibiotics. We emphasized the essential need for further studies, especially randomized clinical trials and longitudinal studies, to better standardize HBOT procedures as well as to determine its full benefits and possible side effects.

Current Trends in Volume and Surgical Outcomes in Gastric Cancer

Gastric cancer is ranked as the fifth most frequently diagnosed type of cancer. Complete resection with adequate lymphadenectomy represents the goal of treatment with curative intent. Quality assurance is a crucial factor in the evaluation of oncological surgical care, and centralization of healthcare in referral hospitals has been proposed in several countries. However, an international agreement about the setting of "high-volume hospitals" as well as "minimum volume standards" has not yet been clearly established. Despite the clear postoperative mortality benefits that have been described for gastric cancer surgery conducted by high-volume surgeons in high-volume hospitals, many authors have highlighted the limitations of a non-composite variable to define the ideal postoperative period. The textbook outcome represents a multidimensional measure assessing the quality of care for cancer patients. Transparent and easily available hospital data will increase patients' awareness, providing suitable elements for a more informed hospital choice.

Extended Lymphadenectomy for Gastric Cancer in the Neoadjuvant Era: Current Status, Clinical Implications and Contentious Issues

Despite its decreasing incidence, gastric cancer remains an important global healthcare problem due to its overall high prevalence and high mortality rate. Since the MAGIC and FNLCC/FFCD trials, the neoadjuvant chemotherapy has been recommended throughout Europe in gastric cancer. Potential benefits of preoperative treatments include a higher rate of R0 resection achieved by downstaging the primary tumor, a likely effect on micrometastases and isolated tumor cells in the lymph nodes, and, as a result, improved cancer-related survival. Nevertheless, distortion of anatomical planes of dissection, interstitial fibrosis, and sclerotic tissue changes may increase surgical difficulty. The collection of at least twenty-five lymph nodes after neoadjuvant therapy would seem to ensure removal of undetectable node metastasis and reduce the likelihood of locoregional recurrence. It is not what you take but what you leave behind that defines survival. Therefore, para-aortic lymph node dissection is safe and effective after neoadjuvant chemotherapy, in both therapeutic and prophylactic settings. In this review, the efficacy of adequate lymph node dissection, also in a neoadjuvant setting, has been investigated in the key studies conducted to date on the topic.

Transanal hemorrhoidal dearterialization (THD) for hemorrhoidal disease: An Italian single-institution 5-year experience analysis and updated literature review

BACKGROUND

Hemorrhoidal disease is a highly prevalent, chronic disorder that usually compromise patients' quality of life. Despite recent advances in pharmacologic and surgical therapeutic options, a clear treatment "gold standard" is lacking. Our aim is to analyze the outcomes following Transanal Hemorrhoidal Dearterialization (THD) procedure.

METHODS

Patients who failed conservative treatment and underwent THD Doppler between 2017 and 2021 were enrolled. Follow-up interviews (consisting of clinical examination, Visual Analog Scale for pain-VAS, Vaizey incontinence score, Hemorrhoid Severity Score) were administered 1 week, 2 weeks, 1 month and 6 months after surgery.

RESULTS

Forty-seven out of 75 patients were male, and the mean age was 50 (± 17.9) years. Hemorrhoids were classified as Goligher's degree II in 25 cases, III in 40 and IV, simple irreducible without ischemic changes, in 10. The mean operative time was 35 (28-60) minutes, and most procedures were performed with epidural anesthesia (80%). No intraoperative complications occurred, and 73 patients (97.3%) were discharged within post-operative day 1. Early post-operative pain and bleeding occurred in 37.3% and 8% of patients, respectively. No patients experienced anal incontinence and severe symptoms at 6 months after surgery. The overall success rate was 97.3%.

CONCLUSIONS

THD is safe and effective in hemorrhoidal disease at degree II if bleeding, III, and IV without ischemic changes, both as a first intervention and on recurrence. Physician and patient need to understand each other's expectations, weight the risks and benefits, and customize the treatment.

Meta-Analysis of Clinical Trials Comparing Cefazolin to Cefuroxime, Ceftriaxone, and Cefamandole for Surgical Site Infection Prevention

Surgical site infections are among the most prevalent and costly healthcare-associated infections, resulting in poor patient outcomes and even death. Cefazolin is a first-generation cephalosporin antibiotic that is widely used for surgical prophylaxis in a variety of surgical disciplines. Although previous studies showed that cefazolin is effective in preventing surgical site infections, other agents, such as cefuroxime and ceftriaxone, were used excessively for surgical patients. The present analysis included only clinical trials comparing the efficacy of cefazolin to cefuroxime, ceftriaxone, and cefamandole in lowering SSIs using PubMed, Google Scholar, and ClinicalTrials.gov. Review Manager software (RevMan version 5.4) was used to conduct the meta-analyses. A total of 12,446 patients were included in the study. Among these patients, 6327 patients received cefazolin and 6119 patients received cefamandole, cefuroxime, or ceftriaxone. Our analysis showed that cefazolin is as effective as cefuroxime, cefamandole, and ceftriaxone in preventing surgical site infections. Hence, our findings have provided evidence for the use of cefazolin before surgeries because of its efficacy, as previous studies showed that it is inexpensive and safer than other agents.
