Background: Enhanced recovery after surgery (ERAS) programs have demonstrated efficacy in optimizing perioperative care and improving patient outcomes in various surgeries. However, their implementation and outcomes in resource-limited settings remain underexplored. This study aimed to assess the implementation of an ERAS protocol for laparoscopic cholecystectomy in such a setting.

Methods: This prospective non-randomized controlled trial involved 100 patients undergoing laparoscopic cholecystectomy at the University Teaching Hospital of Kigali, Rwanda. The first 50 patients on the ERAS pathway were prospectively evaluated and retrospectively compared to the last 50 patients operated on before ERAS implementation. Data on demographics, preoperative information, intraoperative compliance, postoperative events, and patient feedback were collected and analyzed.

Results: ERAS implementation resulted in a significant reduction in hospital length of stay (LOS) (p < 0.001) without increase in complications. Compliance with ERAS principles, including preoperative education and perioperative management, was more than 90%. ERAS also reduced costs due to quicker recovery and shorter hospital LOS.

Conclusion: The implementation of ERAS for laparoscopic cholecystectomy in a limited-resource setting is feasible and safe, suggesting the possibility of its potential adoption in other abdominal procedures. A high level of adherence to the ERAS pathway can be achieved with effective patient education and the dedication of healthcare providers.

Background: Existing studies suggest a positive correlation between high compliance with enhanced recovery programs (ERP) and improved outcomes. While individual outcome measures have advantages, composite benchmarks, such as textbook outcome (TO), offer a more comprehensive assessment of healthcare performance. Given the link between ERP and postoperative outcomes, this study aims to investigate the impact of ERP on TO attainment after liver surgery (LS).

Methods: A prospective multicenter cohort of patients undergoing LS and exposed to ERP from 2016 to 2022 in France was analyzed. The primary outcome was to compare the rates of TO achieved between patients with high ERP compliance (>70%) and those with low ERP compliance (<70%) after LS.

Results: A total of 706 patients were included in the study, and 217 (30.7%) achieved TO: 170 patients with high ERP compliance (24%) versus 47 patients (6.6%) with low ERP compliance attained TO (p < 0.001). High ERP compliance was associated to an increased likelihood of achieving TO [odds ratio (OR) = 1.49 (95% CI: 1.01, 2.24); p = 0.049], while cholangiocarcinoma [OR = 0.11 (95% CI: 0.02, 0.39); p = 0.003], high complexity LS [OR = 0.22 (95% CI: 0.13, 0.36); p < 0.001], intraoperative hypotension requiring vasopressors [OR = 0.29 (95% CI: 0.10, 0.68); p = 0.010], and post-operative ileus [OR = 0.08 (95% CI: 0.00, 0.37); p = 0.013] were negatively associated to the likelihood of achieving TO.

Conclusions: Patients with high ERP compliance after LS experience elevated rates of TO, compared to those with low ERP compliance.

Background: Hypoglycemia after pheochromocytoma resection is one of the most common postoperative complications, with a reported incidence of 12%-43%. In recent years, we have rarely experienced postoperative hypoglycemia after pheochromocytoma surgery at our institution. We reviewed our own experience and examined factors associated with postoperative hypoglycemia in pheochromocytoma patients.

Methods: We collected and retrospectively reviewed medical information from 53 patients with pheochromocytoma who underwent initial surgery in our department between 1996 and 2022, who did not receive steroids in the perioperative period and received the same alpha-blocker preoperatively. Subjects were divided into two groups by the midpoint of the study period: Group 1 (G1), 1996-2009; and Group 2 (G2), 2010-2022. The two groups were compared.

Results: Hypoglycemia occurred significantly less often in G2 (0 patients, 0%) than in G1 (7 patients, 28%; p = 0.003). Preoperative diabetes was significantly less frequent in G2 (2 patient, 7.1%) than in G1 (8 patients, 32%; p = 0.03). Preoperative alpha-blocker dosage was significantly higher in G2 than in G1 (p = 0.04). Multivariate logistic regression analysis showed that only alpha-blockers dosage was significantly associated with the occurrence of postoperative hypoglycemia (p = 0.004).

Conclusion: The current study suggest that the alpha-blocker dosage might be related to the lower incidence of postoperative hypoglycemia in Pheochromocytoma patients.

Background: Major trauma is a leading cause of death and disability in younger individuals and poses a significant public health concern. There is a growing interest in understanding the complex relationships between socioeconomic deprivation and major trauma. Anecdotal evidence suggests that deprivation is associated with more violent and debilitating injuries. There remains a paucity in literature evaluating major trauma outcomes in relation to socioeconomic deprivation.

Methods: A comprehensive search of MEDLINE, Embase, and CENTRAL databases was performed to identify studies from 1947 to March 2024. The primary outcome was to establish the distribution of injuries based on deprivation, with secondary outcomes evaluating surgical intervention rates, length of stay, and mortality. Quantitative pooling of data was based on the random-effects model.

Results: Fourteen studies and 878,872 trauma patients were included. A substantial proportion (28%) of trauma incidents occurred in the most deprived group. Patients from the lowest socioeconomic group were considerably younger (weighted mean difference [WMD] -9.85 years and 95% confidence intervals [CI] -9.99 to -9.70) and more likely to be male (odds ratio [OR] 1.36 and 95% CI 1.14-1.63). There were no differences in surgical intervention (OR 1.74 and 95% CI 0.97-3.13), length of stay (WMD 1.15 days and 95% CI -0.32-2.62), and mortality (OR 1.04 and 95% CI 0.95-1.14) regardless of background.

Conclusion: Major trauma is prevalent in deprived areas and in younger individuals, with an increasing trend of deprivation in male patients. Although the rates of surgery, length of stay, and mortality did not differ between groups, planning of public health interventions should target areas of higher deprivation.

Background: Seroma is the most common complication after breast surgery. Some studies showed that tranexamic acid (TA) can be used in breast surgery to reduce seroma formation and drain volume. We studied the effect of intra-operative and postoperative topical TA on the duration of drain and volume of seroma in patients undergoing axillary lymph node dissection (ALND) for breast cancer.

Patients and methods: Breast cancer patients planned for ALND were enrolled in the study between July 2020 and July 2021. Patients were randomized into three groups where one group (n = 50) received a single intraoperative dose of diluted topical TA, the second group, in addition, received daily postoperative doses till day 5 through the suction drain, and the third group (n = 50) did not receive any dose. Chi-square tests and ANOVA were used to analyze the primary outcomes-the total volume of drain fluid and total drain duration, and secondary outcomes-daily drain output till postoperative-day-5, wound infection, and seroma rates.

Results: Patients receiving multiple doses of topical TA had a decreasing trend in total drain volume, although this was not statistically significant (1597 vs. 1763 vs. 1773 mL: p = 0.269). There was no significant change in the duration of the postoperative drain (21.6 vs. 19.2 vs. 19.55 days: p = 0.54). There was no statistically significant difference in complications between the groups.

Conclusion: There is no significant reduction in drain duration, total drain volume, or the rate of complications with the use of single or multiple doses of topical TA.

Background: Following the 2022 Russian invasion, Ukraine's healthcare system suffered extensive damage, with over 1000 medical facilities destroyed, exacerbating the trauma care crisis. The absence of standardized trauma training left Ukrainian healthcare providers ill-equipped to manage the surge in trauma cases amid conflict. To bridge this gap, we implemented advanced trauma life support (ATLS) courses in Ukraine amid active warfare, aiming to enhance trauma care expertise among healthcare professionals.

Methods: A consortium, including the International Medical Corps, Harvard Humanitarian Initiative, and others, responded to a request from the Ukrainian Ministry of Health. The ATLS curriculum, translated into Ukrainian, guided the training, with US-based instructors sent to Ukraine for teaching. Despite logistical challenges, such as missile attacks and curfews, the courses ran in multiple Ukrainian cities over 3 months. Course effectiveness was evaluated through pre- and post-course knowledge tests, self-efficacy surveys, and satisfaction assessments.

Results: Ten ATLS courses trained 213 Ukrainian healthcare providers across five deployments. Significant improvements in knowledge scores (p < 0.05) and enhanced self-reported confidence in trauma management were observed. Notably, no casualties were reported among instructors or students, highlighting program safety despite security challenges.

Conclusions: Our study demonstrates successful ATLS course implementation in an active war zone, filling a critical gap in trauma education in Ukraine. Despite challenges, the program significantly enhanced participants' trauma care knowledge and confidence. Collaboration between international and local partners was pivotal. This model can serve as a valuable framework for trauma education globally, improving outcomes in conflict zones and resource-limited settings.

Background: Narrow band imaging-magnifying endoscopy (NBI-ME) is used to identify changes in mucosal or vascular pattern observed on GI endoscopy in real time on the basis of optical image enhancement.It has a significant role in early detection of dysplasia, premalignant, and Malignant lesions along with its depth of invasion.

Materials and methods: Upper and lower GI endoscopy performed in 1742 patients who presented with gastrointestinal symptoms at this tertiary center over 5 years out of which 1623 were evaluated with both NBI-ME and histopathology. Real time endoscopic assessment was performed. Targeted biopsies were taken for comparative analysis.

Results: Of the 1742 patients, 119 were excluded from the study. 807 underwent upper GI endoscopy and 816 underwent lower GI endoscopy. Mean age of presentation was 38 +/- 2.7 years. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of NBI-ME for neoplastic esophageal lesions were 96.3%, 90.6%, 91.1%, 96.03%, respectively. For Barrett's esophagus it was 95.4%, 90.7%, 86.1%, and 90.7%; For gastric neoplastic lesions the values were 96.1%, 91.04%, 83.8%, and 97.9%. For colorectal it was 96.7%, 91.3%, 88.0%, and 97.7%. Overall sensitivity, specificity, PPV, and NPV of NBI-ME for neoplastic lesions (both upper and lower GI) were 96.2%, 91.0%, 96.2%, and 97.2%. Of the 1623 patients, 951 received medical management with regular surveillance and 672 patients with high-grade dysplasia, premalignant, and malignant conditions underwent interventions in form of either endoscopy or surgery.

Conclusion: NBI-ME has a greater role and can be considered as an effective tool in making early diagnosis and guiding optimum treatment.
