Background: Morbidity and mortality after surgical treatment of bileduct stones increase with age and associated diseases. A proposed alternative therapy is endoscopic sphincterotomy (ES) with the gallbladder left in situ, and we elected to compare this option with standard open surgery in high-risk patients.Methods: 98 patients (mean age 80 years) with symptoms likely to be due to bileduct stones or a recent episode of biliary parcreatitis were randomised to be treated either by open cholecystectomy with operative cholangiography and (if necessary) bileduct exploration (n=48) or by endoscopic sphincterotomy alone (n=50).Findings: The procedure was accomplished successfully in 94% of the surgery group and 88% of the ES group, and there were no significant differences in immediate morbidity (23%vs16%) or mortality (4%vs6%). During mean follow-up of 17 months biliary symptoms recurred in three surgical patients, none of whom underwent repeat surgery, and in 10 ES patients, seven of whom had biliary surgery. By multivariate regression analysis endoscopic sphincterotomy was an independent predictor of recurrent biliary symptoms (odds ratio 6.9; 95% C11.46 to 32.54).Interpretation: In elderly or high-risk patients, surgery is preferably to endoscopic sphincterotomy with the gallbladder leftin situas a definitive treatment for bileduct stones or non-severe biliary pancreatitis.
