Prophylactic cholecystectomy ofers best outcomes following ERCP clearance of common bile duct stones: a meta‑analysis
Background Symptomatic calculus biliary disease is common with associated morbidity and occasional mortality, further confounded when there is concomitant common bile duct (CBD) stones. Choledocholithiasis and clearance of the duct reduces recurrent cholangitis, but the question is whether after clearance of the CBD if there is a need to perform a cholecystectomy. This meta-analysis evaluated outcomes in patients undergoing ERCP with or without sphincterotomy to determine if cholecystectomy post-ERCP clearance ofers optimal outcomes over a wait-and-see approach.
Methods A Prospero registered meta-analysis of the literature using PRISMA guidelines incorporating articles related to ERCP, choledocholithiasis, cholangitis and cholecystectomy was undertaken for papers published between 1st January 1991 and 31st May 2021. Existing research that demonstrates outcomes of ERCP with no cholecystectomy versus ERCP and cholecystectomy was reviewed to determine the related key events, complications and mortality of leaving the gallbladder in situ and removing it. Odds ratios (OR) were calculated using Review Manager Version 5.4 and meta-analyses performed using OR using fxed-efect (or random-efect) models, depending on the heterogeneity of studies.
Results 13 studies (n=2598), published between 2002 and 2019, were included in this meta-analysis, 6 retrospective, 2 propensity score-matched retrospective studies, 3 prospective studies and 2 randomised control trials from a total of 11 countries. There were 1433 in the no cholecystectomy cohort (55.2%) and 1165 in the prophylactic cholecystectomy (44.8%) cohort. Cholecystectomy resulted in a decreased risk of cholecystitis (OR=0.15; CI 0.07–0.36; p<0.0001), cholangitis (OR=0.51; CI 0.26–1.00; p=0.05) and mortality (OR=0.38; CI 0.16–0.9; p=0.03). In addition, prophylactic cholecystectomy resulted in a signifcant reduction in biliary events, biliary pain and pancreatitis.
Conclusions In patients undergoing CBD clearance, consideration should be given to performing prophylactic cholecystectomy to optimise outcom
