Abstract
IntroductionWith severely inflamed gallbladders, laparoscopic cholecystectomy can be difficult and may require procedures like subtotal cholecystectomy (SC). Few studies exist comparing SC and total cholecystectomy (TC) in the setting of severe biliary inflammation. This meta-analysis aims to compare SC and TC for difficult gallbladders. MethodsMedline-OVID, Embase-OVID, and Cinahl were searched including only studies comparing SC to TC for difficult gallbladders. Primary outcome was CBD injury. Secondary outcomes included bile leak, duodenal injury, retained stone, bleeding, intraabdominal collection, wound infection, reoperation, and mortality. ResultsTen studies were included. Compared to TC, SC significantly lowered the risk for CBD injury (0 % vs. 1.6 %, RR 0.30, 95%CI 0.10–0.87) but increased risk of bile leaks (RR 3.5, 95%CI 1.79–6.84), postoperative ERCP (RR 2.86, 95%CI 1.53–5.35), intraabdominal collections (RR 2.55, 95%CI 1.32–4.93), and reoperation (RR 2.92, 95%CI 1.14–7.47). ConclusionSC is a reasonable alternative to difficult gallbladders that may decrease the risk of CBD injuries. Knowing both approaches is crucial to manage the difficult gallbladder while minimizing harm. Further studies are needed to understand the value of SC for difficult cholecystectomy.
