Comparison of Long-Term Outcomes Between Conversion to Open and Laparoscopic Subtotal Cholecystectomy in the...

BackgroundA difficult laparoscopic cholecystectomy (LC) confers an increased risk of bile duct injury. Traditionally, surgeons convert to open cholecystectomy (OC) as a bailout procedure for safer dissection. Laparoscopic subtotal cholecystectomy (LSC) has recently gained favor with comparable short-term complication rates, but differences in long-term outcomes remain unknown. We sought to compare long-term biliary outcomes between OC and LSC.Study DesignWe performed a single-center retrospective cohort study of adults who underwent non-elective LC converted to OC or LSC due to difficult dissection from 1/1/2015 to 12/31/2019. The primary outcome was a composite measure of postoperative biliary events, and we used time-to-event analysis to compare the 2 groups. We evaluated secondary outcomes using Chi-squared or independent t-tests as appropriate.ResultsOf 1089 patients who underwent non-elective LC, 68 (6%) underwent a bailout procedure (30 OC vs 38 LSC). There were no differences in demographics or comorbidities between the groups. Most patients (84%) had acute cholecystitis. Average follow-up times were 40 ∓ 29 months in OC and 54 ∓ 21 months in LSC. Biliary events occurred in 13 total patients (19%) with OC most commonly suffering bile leak (17%) and LSC most commonly having choledocholithiasis (11%). Kaplan-Meier analysis demonstrated no significant difference in biliary events between the groups (P = 0.71). Secondary outcomes were all similar between groups, except LSC had a shorter length of stay (2.9 ∓ 2.3 vs 5.1 ∓ 3.6 days, P = 0.002).ConclusionsOC and LSC demonstrated comparable long-term biliary outcomes. In a difficult LC, surgeons may perform either bailout procedure to safely manage the gallbladder.
