A comparison of outcomes including bile duct injury of subtotal cholecystectomy versus open total cholecystectomy as bailout procedures for severe cholecystitis: A multicenter real-world study.

BACKGROUND: Dense inflammation obscuring the hepatocystic anatomy can hinder the ability to perform a safe standard laparoscopic cholecystectomy in severe cholecystitis, requiring use of a bailout procedure. We compared clinical outcomes of laparoscopic and open subtotal cholecystectomy against the traditional standard of open total cholecystectomy to identify the optimal bailout strategy for the difficult gallbladder. METHODS: A multicenter, multinational retrospective cohort study of patients who underwent bailout procedures for severe cholecystitis. Procedures were compared using one-way analysis of variance/Kruskal-Wallis tests and χ2 tests with multiple pairwise comparisons, maintaining a family-wise error rate at 0.05. Multiple multivariate linear/logistical regression models were created. RESULTS: In 11 centers, 727 bailout procedures were conducted: 317 laparoscopic subtotal cholecystectomies, 172 open subtotal cholecystectomies, and 238 open cholecystectomies. Baseline characteristics were similar among subgroups. Bile leak was common in laparoscopic and open fenestrating subtotal cholecystectomies, with increased intraoperative drain placements and postoperative endoscopic retrograde cholangiopancreatography(P < .05). In contrast, intraoperative bleeding (odds ratio = 3.71 [1.9, 7.22]), surgical site infection (odds ratio = 2.41 [1.09, 5.3]), intensive care unit admission (odds ratio = 2.65 [1.51, 4.63]), and length of stay (Δ = 2 days, P < .001) were higher in open procedures. Reoperation rates were higher for open reconstituting subtotal cholecystectomies (odds ratio = 3.43 [1.03, 11.44]) than other subtypes. The overall rate of bile duct injury was 1.1% and was not statistically different between groups. Laparoscopic subtotal cholecystectomy had a bile duct injury rate of 0.63%. CONCLUSION: Laparoscopic subtotal cholecystectomy is a feasible surgical bailout procedure in cases of severe cholecystitis where standard laparoscopic cholecystectomy may carry undue risk of bile duct injury. Open cholecystectomy remains a reasonable option.

How We Do It: Surgery IMPACT - Integrated Mentorship Program for Advancing Clinical Training.

OBJECTIVE: Effective mentorship plays a crucial role in the professional development of surgical residents by providing guidance, support, networking, and facilitating personal, and career growth. This is particularly significant for female and underrepresented minority residents who often encounter additional challenges due to discrimination and historical lack of representation. Our objective is to present a framework for structuring a progressive and inclusive formal mentorship program- Surgery IMPACT- which embodies a panoramic perspective of surgery residency. DESIGN: A holistic mentorship program was created through the conceptualization of WISE Domains (Work-Life Balance, Interpersonal and cultural proficiency, Scholarly and career advancement, Effective learning and study techniques). Mentor-Mentee partnerships were created between current surgical faculty and general surgery residents. The foundation of the program is built upon four essential mentor roles: Core faculty mentor, research mentor, fellowship mentor, alongside a concurrent incorporation of peer mentorship. Over the academic year, we encouraged at least 3 formal mentorship meeting prefaced by a reflective exercise by the residents. CONCLUSIONS: The implementation of Surgery IMPACT has been successful in formalizing mentorship opportunities at our institution. By incorporating WISE domains, structured meeting centered on well-defined objectives, we have effectively created an all-inclusive mentorship program to foster resident growth and equal opportunities. Our ongoing commitment is to further refine and expand this innovative program with the aspiration of galvanizing similar mentorship models across diverse surgical programs.

30-day Morbidity and Mortality after Cholecystectomy for Benign Gallbladder Disease (AMBROSE): A Prospective, International Collaborative Cohort Study.

OBJECTIVE: This study aimed to assess 30-day morbidity and mortality rates following cholecystectomy for benign gallbladder disease and identify the factors associated with complications. SUMMARY BACKGROUND DATA: Although cholecystectomy is common for benign gallbladder disease, there is a gap in the knowledge of the current practice and variations on a global level. METHODS: A prospective, international, observational collaborative cohort study of consecutive patients undergoing cholecystectomy for benign gallbladder disease from participating hospitals in 57 countries between January 1 and June 30, 2022, was performed. Univariate and multivariate logistic regression models were used to identify preoperative and operative variables associated with 30-day postoperative outcomes. RESULTS: Data of 21,706 surgical patients from 57 countries were included in the analysis. A total of 10,821 (49.9%), 4,263 (19.7%), and 6,622 (30.5%) cholecystectomies were performed in the elective, emergency, and delayed settings, respectively. Thirty-day postoperative complications were observed in 1,738 patients (8.0%), including mortality in 83 patients (0.4%). Bile leaks (Strasberg grade A) were reported in 278 (1.3%) patients and severe bile duct injuries (Strasberg grades B-E) were reported in 48 (0.2%) patients. Patient age, ASA physical status class, surgical setting, operative approach and Nassar operative difficulty grade were identified as the five predictors demonstrating the highest relative importance in predicting postoperative complications. CONCLUSION: This multinational observational collaborative cohort study presents a comprehensive report of the current practices and outcomes of cholecystectomy for benign gallbladder disease. Ongoing global collaborative evaluations and initiatives are needed to promote quality assurance and improvement in cholecystectomy.

Bailout Surgery for Difficult Gallbladders: Surgical Approach and Outcomes.

INTRODUCTION: Inflammation in acute cholecystitis may cause a cholecystectomy to be more challenging. Due to the difficult dissection, conversion to subtotal cholecystectomy via laparoscopic or open procedure may be required. This is done to reduce the risk of bile duct injury and hemorrhage. We sought to describe the incidence and risk factors, safety, morbidity, and outcomes associated with bailout procedures. METHODS: A single academic center, retrospective review of laparoscopic cholecystectomies that resulted in bailout procedures performed between January 2015 and December 2020. Data collected from the chart review included demographics, comorbidities, length of presenting symptoms, vital signs, laboratory and imaging, intraoperative findings, length of surgery, and outcome. RESULTS: A total of 1892 cholecystectomies were performed with 147 bailout procedures. For bailout 92 (63.4%) were converted to open, with 66% resulting in complete cholecystectomy. Hypertension and diabetes were the most common comorbidities. The median duration of symptoms was 4 days. Difficult anatomy in the hepatocystic triangle (66%) and dense adhesions (31%) were the most common reasons for bailout. The mean duration of surgery was 145.76 (SD 102.94) minutes. There were 2 bile duct injuries, both in open total cholecystectomy subgroup. Bile leak occurred in 23.8% with majority in subtotal cholecystectomy group. There was no difference in hospital length of stay, surgical site infection, or mortality among different bailout procedures. CONCLUSIONS: Subtotal cholecystectomy represents a safe alternative to total cholecystectomy during challenging cases to avoid damaging surrounding structures. The choice of laparoscopic or open subtotal approach is dependent on the surgeons' expertise.

Operating Ethically: A Review of Surgical Ethics in Pakistan and Recommendations for the Way Forward.

Medical ethics underpin the moral framework that delineates the professional relationship between physicians and their patients and thereby is an integral part of making patient-centric healthcare decisions. The concept of ethics is deeply embedded in the field of surgery as surgeons confront a myriad of dilemmas as a part of their routine, whether it be in a preoperative or postoperative environment. The current review aims to describe the state of surgical ethics in Pakistan, with the intent of encouraging dialogues about the ethical considerations relevant to the field surgery that will identify actionable areas for improvement. While most surgeons are aware of the traditional principles of ethics and their practice, their surgical and clinical decisions may fall short of these standards because of time constraints and prevailing cultural and religious beliefs and taboos. The rigorous application of ethical principles in areas of patient-related communication, such as consenting, trainee education, palliative and end-of-life care, and surgical innovation and research, will have significant implications for patients, surgeons, and society. Our review has identified the lack of formal bioethics education and insufficient oversight and ethical regulations to be at the core of inadequate ethical practices in Pakistan and has highlighted actionable areas to be addressed in the future.

Shedding Light on the Hidden Curriculum: A Systematic Review of Ethics Education during General Surgery and Subspecialty Training.

INTRODUCTION: Ethics education in surgical residencies is often delivered in an informal and nonstructured manner as part of a "hidden curriculum", leading to few residencies routinely including it in their core curriculum. This systematic review aimed to summarize the delivery modes, curriculum, structure, and effectiveness of ethics educational interventions for surgical trainees. METHODS: We performed a comprehensive database search including MEDLINE, Embase, Scopus and CENTRAL to search for articles describing the implementation of ethics educational interventions for general surgery or subspecialty trainees. RESULTS: A total of 14 studies were included. Only 2 centers performed targeted needs assessment. Curricula covered included informed consent, the doctor-patient relationship, breaking bad news, decision-making, end-of-life care, conflicts of interest, considering patients' personal contexts, and surgical research ethics. Modes of delivery varied across studies, including case-based learning, group discussions, didactic lectures, reading material, role-playing, simulated patients, and ethics morbidity and mortality (M&M) meetings. Evaluations were most commonly via surveys exploring knowledge and self-reported confidence, with only 3 studies measuring actual trainee performance using objective structured clinical examinations. In general, the educational interventions increased trainees' confidence/preparedness in handling ethical dilemmas. CONCLUSION: We recommend comprehensive local needs assessment to guide curricular development and designing specific learning objectives and measurable milestones to ensure evaluation. Educational interventions are best delivered in a graduated manner with the complexity of the topic mirroring residents' real-life clinical responsibilities and experiences. Teaching modalities should be tailored according to the nature of the curricular content being taught to make the learning experience more interactive and effective.

Contemporary management and outcomes of penetrating colon injuries: Validation of the 2020 AAST Colon Organ Injury Scale.

INTRODUCTION: The American Association for the Surgery of Trauma Colon Organ Injury Scale (OIS) was updated in 2020 to include a separate OIS for penetrating colon injuries and included imaging criteria. In this multicenter study, we describe the contemporary management and outcomes of penetrating colon injuries and hypothesize that the 2020 OIS system correlates with operative management, complications, and outcomes. METHODS: This was a retrospective study of patients presenting to 12 Level 1 trauma centers between 2016 and 2020 with penetrating colon injuries and Abbreviated Injury Scale score of <3 in other body regions. We assessed the association of the new OIS with surgical management and clinical outcomes and the association of OIS imaging criteria with operative criteria. Bivariate analysis was done with χ 2 , analysis of variance, and Kruskal-Wallis, where appropriate. Multivariable models were constructed in a stepwise selection fashion. RESULTS: We identified 573 patients with penetrating colon injuries. Patients were young and predominantly male; 79% suffered a gunshot injury, 11% had a grade V destructive injury, 19% required ≥6 U of transfusion, 24% had an Injury Severity Score of >15, and 42% had moderate-to-large contamination. Higher OIS was independently associated with a lower likelihood of primary repair, higher likelihood of resection with anastomosis and/or diversion, need for damage-control laparotomy, and higher incidence of abscess, wound infection, extra-abdominal infections, acute kidney injury, and lung injury. Damage control was independently associated with diversion and intra-abdominal and extra-abdominal infections. Preoperative imaging in 152 (27%) cases had a low correlation with operative findings ( κ coefficient, 0.13). CONCLUSION: This is the largest study to date of penetrating colon injuries and the first multicenter validation of the new OIS specific to these injuries. While imaging criteria alone lacked strong predictive value, operative American Association for the Surgery of Trauma OIS colon grade strongly predicted type of interventions and outcomes, supporting use of this grading scale for research and clinical practice. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

Delayed Formation of Traumatic Ulnar Artery Pseudoaneurysm Presenting With Ulnar Nerve Palsy: A Case Report.

Ulnar artery pseudoaneurysm (UAP) is a rare occurrence after penetrating injury to the distal upper extremity and may lead to complications such as rupture, sensorimotor dysfunction, and compartment syndrome. We present the case of a 57-year-old man who developed delayed UAP after suffering a penetrating injury to the right forearm. UAP was diagnosed a week after the injury using CT angiography (CTA), which was indicated due to the onset of ulnar nerve palsy (mildly reduced hand-grip strength and fourth- and fifth-digit hypoesthesia and numbness) and growing swelling and tenderness of the right forearm. Due to concerns about UAP and hematoma formation, with resultant compression of the ulnar nerve and suspected hematoma infection, surgical intervention was performed wherein a moderate-size hematoma was evacuated and the ulnar artery was ligated. The decision to ligate rather than reconstruct was based on the suspected infected nature of the hematoma and adequate perfusion of the palmar arch by the radial artery. This case highlights the need for maintaining a strong index of suspicion for UAP after penetrating trauma to the distal upper extremity, due to the possibility of debilitating nerve deficits and compartment syndrome complicating late diagnosis. We also present an algorithm for the choice of management modality for UAP, which is a valuable addition to the existing literature.

Acute kidney injury in dengue virus infection.

BACKGROUND: Dengue is a growing public health problem in Pakistan and acute kidney injury (AKI) is one of the least studied complications of dengue virus infection (DVI). The aim of this study was to determine the frequency, severity and predictors of AKI in patients with DVI and to study the impact of AKI on the length of hospital stay and mortality. METHODS: We retrospectively reviewed medical records of patients aged ≥14 years hospitalized with a primary diagnosis of DVI at Aga Khan University Hospital Karachi between January 2008 and December 2010. Binary logistic regression models were constructed to identify factors associated with the development of AKI and to study the impact of AKI on hospital stays of more than 3 days. RESULTS: Out of 532 patients, AKI was present in 13.3% (71/532). Approximately two-thirds (64.8%) of these patients had mild AKI and a third (35.2%) had moderate to severe AKI. Independent predictors for AKI were male gender [odds ratio (OD) 4.43; 95% CI 1.92-10.23], presence of dengue hemorrhagic and dengue shock syndrome (DSS, OD 2.14; 95% CI 1.06-4.32), neurological involvement (OD 12.08; 95% CI 2.82-51.77) and prolonged activated partial thromboplastin time (aPTT, OD 1.81; 95% CI 1.003-3.26). AKI was associated with a length of stay ≥3 days when compared with those who did not have AKI (OD 2.98; 95% CI 1.66-5.34). Eight patients (11.3%) with AKI died whereas there were no mortalities in patients without AKI (P < 0.001). Only 5 patients (7%) had persistent kidney dysfunction at discharge. CONCLUSIONS: AKI in DVI is associated with neurological involvement, prolongation of aPTT, greater length of hospital stay and increased mortality.
