Comparative Surgical Outcomes of Bailout Procedures versus Standard Laparoscopic Cholecystectomy for Acute Cholecystitis: A Systematic Review and Meta-Analysis of Observational Studies

Abstract

Background & Objective: The Tokyo Guidelines 2018 state that in cases of severe acute cholecystitis and bailout procedures (subtotal cholecystectomy, fundus-first approach, or conversion to open surgery), the critical view of safety in laparoscopic cholecystectomy may be dangerous. Although their safety in comparison to standard LC is still unknown, bailout procedures may reduce the risk of bile duct damage during dissection. In this meta-analysis, bailout procedures and standard LC for acute cholecystitis were compared for perioperative, intraoperative, and postoperative outcomes. Methodology: A systematic review and meta-analysis of observational cohort studies were carried out per PRISMA and the Cochrane Protocols (PROSPERO: CRD420261455055). We searched PubMed, Embase, and Scopus in July 2026. Study quality was evaluated by the Newcastle-Ottawa Scale. Risk ratios (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes were combined in a random-effects model with 95% confidence intervals (CI). For varied results, a leave-one-out sensitivity analysis was carried out. Results: Included were nine observational cohort studies involving 4,102 patients (3,433 standard laparoscopic cholecystectomy, 669 bailout). For the majority of results, standard laparoscopic cholecystectomy was recommended. Preoperative gallbladder drainage (RR=1.94), bile duct injury (RR=4.83), postoperative bile leak (RR=4.77), overall complications (RR=2.19, all p<0.05), operative time (MD=48.64 min), intraoperative blood loss (MD=61.43 mL), and hospital stay (MD=3.38 days, all p<0.05) were all linked to bailout procedures at significantly higher rates. Despite the higher morbidity linked to bailout procedures, there was no discernible difference in all-cause postoperative mortality between the groups (RR=4.58, 95% CI: 0.62–34.09; p=0.14), suggesting that neither strategy clearly improves survival. Conclusion: Bailout procedures have significant complication rates, longer operating times and hospital stays than normal LC, and more blood loss despite the fact that they are required to prevent dangerous dissection in cases of severe acute cholecystitis. These findings encourage further prospective research and the cautious, case-by-case application of bailout solutions. Key Words: Standard Laparoscopic cholecystectomy, Bail out procedure, Outcomes, acute cholecystitis.
