Abstract
BackgroundAcute cholecystitis is one of the most prevalent surgical abdominal conditions. The Tokyo Guidelines describe the management of acute cholecystitis and recommend bailout procedures for “difficult” cholecystitis cases. This study aimed to identify risk factors for conversion from laparoscopic cholecystectomy to bailout procedures in patients with acute cholecystitis. MethodsThis retrospective cohort study was conducted at a single center between January 2017 and December 2021. Patients who underwent laparoscopic cholecystectomy for acute cholecystitis were enrolled and classified into bailout and non-bailout groups. The patients’ characteristics and perioperative data were compared between the 2 groups. ResultsIn total, 161 patients who underwent laparoscopic cholecystectomy for acute cholecystitis were reviewed. Fourteen were excluded because of a lack of preoperative magnetic resonance cholangiopancreatography; thus, 147 patients were enrolled (bailout group, 21; non-bailout group, 126). Age (74 vs 67 years old; P = .048), days from onset to surgery (3 vs 2 days; P = .02), or defect of cystic duct in magnetic resonance cholangiopancreatography (57% vs 29%; P = .02) were significantly associated with conversion to bailout procedures. In the logistic regression analysis, a defect of the cystic duct in magnetic resonance cholangiopancreatography was an independent predictor for bailout procedures (odds ratio, 2.793; P = .04). ConclusionIn this study, defect of the cystic duct in the magnetic resonance cholangiopancreatography can predict conversion to bailout procedures. To the best of our knowledge, this is the first report to describe magnetic resonance cholangiopancreatography finding of the cystic duct as a predictor of surgical difficulty in patients with acute cholecystitis.
