Biliary atresia is a progressive cholangiopathy in neonates, which often results in liver failure. In high-income countries, initial treatment requires prompt diagnosis followed by Kasai portoenterostomy. For those with a late diagnosis, or those in whom Kasai portoenterostomy fails, liver transplantation is the only lifesaving treatment. Unfortunately, in low- and middle-income countries, timely diagnosis is a challenge and liver transplantation is rarely accessible. Here, we discuss the ethical dilemmas surrounding treatment of babies with biliary atresia in Uganda. Issues that require careful consideration include: risk of catastrophic health expenditure to families, ethical dilemmas of transplant tourism, medical risks of maintaining the transplant in a low-resourced health system, and difficult decisions encountered by the surgeon caring for these patients. Four distinct models of the patient-physician relationship are applied to biliary atresia in Uganda. These models describe differences in patient and physician roles, and patient values and autonomy. Solid organ transplantation is a rapidly evolving segment of healthcare in Uganda and ongoing policy advancements may shift ethical considerations in the future.

Background: Carcinoembryonic antigen (CEA) is one of the commonly used preoperative biomarkers for colorectal cancer (CRC), but no meta-analysis has evaluated the findings of all recently published studies to determine whether its postoperative level can serve as a prognostic indicator.

Methods: We conducted a systematic search for eligible literature from the PubMed, EMBASE, and Web of Science databases in October 2023. Studies that investigated the relationship between postoperative serum CEA levels and prognosis in CRC patients were included. Outcome indicators, including overall survival (OS), disease-free survival (DFS), and progression-free survival (PFS)/recurrence-free survival (RFS), were analyzed using a fixed-effects or random-effects model. The pooled hazard ratios (HR) with 95% confidence intervals (CI) were used as effective values.

Results: This meta-analysis included 20 eligible studies involving 10,114 CRC patients from the East Asian and Western countries. A comprehensive analysis revealed that elevated postoperative CEA levels were associated with low OS (HR: 2.92, 95% CI: 2.36-3.62, and p < 0.000), DFS (HR: 2.81, 95% CI: 2.01-3.94, and p < 0.000), and RFS/PFS (HR: 2.52, 95% CI: 1.75-3.62, p < 0.000). A subgroup analysis by region, analysis type, distant metastasis, HR obtain method, sample size, postoperative measurement date, and study design demonstrated that the negative correlation observed between high serum CEA levels after surgery and poor prognosis was not significantly different between the subgroups.

Conclusion: When CEA levels are found to be elevated during postoperative follow-up, more active intervention measures should be implemented to further improve the patient's survival outcomes.

Compassionate care of the surgical patient recognizes the wholeness of each individual. Patients and their caregivers come to healthcare providers with the hope of relief from pain and suffering and aspirations for the potential to feel well or be "normal" again. Many lean on their personal faith and prayer for spiritual comfort and petitions for healing. We discuss a case in which prayer is incorporated into the surgical Time Out, a scenario not uncommon in faith-based hospitals, and offer a framework to evaluate the practice that incorporates ethical principles of beneficence, non-maleficence, patient/parental autonomy, justice, and the fiduciary responsibility of the healthcare provider.

Background: Laparoscopy training remains inaccessible in many low- and middle-income countries, including Liberia. We assessed the availability of laparoscopy and feasibility of implementing a laparoscopic program among Liberian surgeons and trainees.

Methods: This mixed-methods study utilized a 32-item survey and semi-structured interviews on laparoscopic experience, knowledge, desires, barriers, patient perceptions, and training opportunities among surgeons and trainees at Liberia's two main teaching hospitals in March 2023. Data analysis utilized summed knowledge and desirability scores, descriptive statistics, and qualitative content analysis.

Results: 31 interns, residents, and consultants participated, comprising 60% of Liberia's surgeons. Laparoscopic training (32%) and experience (16%) was low, with exposure limited to those training outside Liberia (p = 0.001). While laparoscopy knowledge varied (29% low, 55% medium, 16% high), participants expressed high interest in training (100%) and willingness to pay (52%). Interviews revealed four themes: desires for training, patient acceptability, feasibility of technology-based training, and barriers including limited equipment and expert trainers. At the time of survey, the only minimally invasive surgeries ever performed in Liberia were two diagnostic laparoscopies.

Conclusions: This is the first mixed-methods study assessing laparoscopy in Liberia. Our sample, though small, comprised approximately 60% of Liberian surgeons in both rural and urban hospitals. Findings demonstrated limited experience, variable knowledge, and high desires for training, showing feasibility for laparoscopy implementation in Liberia.

Background: Urologic emergencies are common and complications from their management are high. Simulation-based education (SBE) is a highly effective training method, allowing trainees to learn both technical and nontechnical skills in a safe environment. Training in the management of urological emergencies is limited in many healthcare settings, so we performed a needs assessment for a urological emergencies SBE course in Ethiopia.

Methods: This study presents data from a descriptive cross-sectional, survey-based survey of consultants and residents in the Ethiopian surgical community. The survey was disseminated using online Google Forms, through social media (WhatsApp), and to colleagues in the College of Surgeons of East, Central and Southern Africa (COSECSA) via email and social media.

Results: One hundred-seven results were received; two were discarded due to incomplete data. Fifty three of the respondents were general surgeons and 38 of the respondents were urologists. Sixty nine respondents strongly agreed that simulation-based training was important for first-year surgical residents, whereas twenty-five respondents agreed and nine respondents strongly disagreed; one respondent disagreed and one was neutral. Eighty seven respondents suggested a 3-day training course, whereas 17 respondents suggested a two-day course. More than 80 of the respondents rated training in the management of acute urinary retention, acute scrotum, urethral, and suprapubic catheterization as extreme or very important and 79 respondents wanted education about urologic trauma and Fournier's gangrene.

Conclusion: Surgical and urology residents in Ethiopia have expressed a need for, and a strong interest in, simulation-based urological emergency training.

Introduction: Estimated blood loss (EBL) is an important part of the perioperative process. This project aims to determine the accuracy of perioperative team members to estimate blood volume on drapes and the operating room floor.

Methods: Aliquots of unused human blood were used to create surgical scenarios, and standardized pictures and videos were taken. Physicians, residents, nurses, medical students, and surgical technicians were surveyed and asked to estimate the blood volume for each series. Accuracy and consistency of responses was analyzed.

Results: One hundred and forty five responses were recorded: 57 attending physicians, 36 residents, 27 registered nurses, 17 medical students, and seven circulating surgical techs. Median percent error (PE) for all cases was 211.11%, demonstrating a global overestimation of blood volume. PE for the 150 mL images was statistically significantly lower than that of the 50 and 100 mL images. Circulating Surgical Technicians were the most accurate group, with a median PE of 125%, followed closely by Medical Students (PE = 158.33%). The most accurate specialty was Orthopedics (PE = 168.06%). The least accurate groups were Attending Physicians (PE = 286.11%) and General surgery (GSGY) (PE = 327.78%). The most accurate orthopedic surgery and GSGY subspecialties were Hand (PE = 237.64%) and Vascular (PE = 108.33%), respectively. Statistical analyses showed no significant differences by clinical role, surgical specialty, or subspecialty.

Conclusion: This study demonstrates a global overestimation of blood volume when using the visual method, with improved accuracy at higher volumes. Our findings highlight the limitations of visual estimation methods for EBL.

Introduction: In low- and middle-income countries such as Haiti, musculoskeletal injuries are the leading cause of morbidity and mortality. Untreated injuries can contribute to decreased mobility, leading to disability and reduced productivity for individuals. The accessibility of timely fracture care poses a substantial challenge in Haiti, where socioeconomic instability and recent surges in gang violence exacerbate an already strained healthcare infrastructure. This manuscript delves into the intricate barriers to sustainable fracture care in Haiti, shedding light on the sociopolitical landscape and clinical challenges that influence the delivery of orthopedic services.

Ethical discussion: The ethical considerations in providing fracture care in Haiti are multifaceted, including classic medical principles, self-preservation in the face of violence, issues of justice in resource and service allocation, and concerns of nonmaleficence in the context of international volunteers. These ethical dilemmas arise from the complex interplay of limited resources, the dangers posed by the current sociopolitical climate, and the involvement of international aid in a vulnerable healthcare system.

Conclusion: To address the clinical and ethical conflicts of providing fracture care in Haiti, solutions include education and training of Haitian orthopedic surgeons, capacity building of healthcare facilities, and establishing ethical standards for international volunteers. This comprehensive approach is vital for advancing sustainable fracture care in Haiti and other resource-limited settings.

Introduction: Open abdomen (OA) therapy is used in the management of patients who require surgery for severe abdominal conditions. This meta-analysis aims to evaluate the VAWCM technique regarding short and long-term outcomes.

Methods: PubMed, Embase, and Cochrane Central were systematically searched for studies that analyzed VAWCM therapy in OA. Primary outcomes were the complete fascial closure rate and mean duration of OA treatment. Statistical analyses were performed using R statistical software.

Results: Seven studies comprising 535 patients were included. We found a complete fascial closure rate of 77.3 per 100 patients (80.1%; 95% CI 59.6-88.7; I² = 76%), with an overall mortality of 30.3 per 100 (33.5%; 95% CI 9.3-19.4; I² = 78%). The pooled mean duration of OA treatment was 14.6 days (95% CI 10.7-18.6; I² = 93%), while the mean length of hospital stay was 43.3 days (95% CI 21.2-65.3; I² = 96%). As additional outcomes, we found an enteroatmospheric fistula rate of 5.6 per 100 patients (5.4%; 95% CI 2.3-13.3; I² = 45%) and incisional hernia rate of 34.7 per 100 (34.6%; 95% CI 28.9-41.1; I² = 0%). The subgroup analysis of mesh materials (polypropylene or polyglactin) showed a higher complete fascial closure rate for the polyglactin (89.1% vs. 66.6%; p = 0.02).

Conclusion: Our findings showed that VAWCM is a viable option for OA treatment, successfully reaching complete fascial closure, with a low duration of the technique, even though it presented a high heterogeneity between the studies.
