Bile Duct Stones Predict a Requirement for Cholecystectomy in Older Patients

Abstract

Background: The requirement for elective cholecystectomy in older patients is unclear. To determine predictors for requiring elective cholecystectomy in older patients, a prospective cohort study was performed. Methods: All patients with gallstone disease who presented to our department from 2006 to 2018 were included if they met the following criteria: (1) age 75 years or older, (2) presentation for elective cholecystectomy, and (3) preoperative diagnosis of cholecystolithiasis. Two therapeutic options, elective surgery and a wait-and-see approach, were offered at their initial visit. Enrolled patients were assigned to one arm of the study according to their choice of the therapeutic options. The primary endpoint was the incidence of gallstone-related complications. The endpoint was compared between patients who underwent cholecystectomy (CH group) and those who chose a wait-and-see approach (No-CH group). Results: During the study period, there were 344 patients in the CH group and 161 in the No-CH group. Among patients with a history of bile duct stones, the incidence of gallstone-related complications in the No-CH group was significantly higher (45% within 3 years, including two gallstone-related deaths) than that in the CH group (RR 2.66, 95% confidence interval 1.50–4.77, p = 0.0009). Among patients with no history of bile duct stones, the incidence of gallstone-related complications in the No-CH group reached only 10% over the 12 years. Conclusion: Cholecystectomy is recommended for older patients with both histories of cholecystolithiasis and bile duct stones, whereas a wait-and-see approach is preferable for patients with no bile duct stone history. A history of bile duct stones is a good predictor for cholecystectomy in older patients.
