Abstract
Background and Aims: In patients who undergo cholecystectomy after endoscopic common bile duct (CBD) stone extraction, CBD stones found postoperatively could be problematic. This study aimed to investigate the incidence and risk factors of postoperative CBD stones after cholecystectomy. Methods: A total of 278 patients (mean age, 59.2 years; 71 men [51.1%]) who underwent endoscopic removal of CBD stones followed by cholecystectomy from January 2013 to December 2017 were included. An endoscopic nasobiliary drainage (ENBD) tube was placed immediately after endoscopic clearance of the CBD stones in all patients until cholecystectomy. An ENBD tubogram was obtained in all patients to determine the presence of postoperative CBD stones. Results: Postoperative CBD stones were detected in 20.1% (56/278). An ENBD tubogram was obtained after an average of 2.42 days postoperatively. Based on univariate analysis, the statistically significant risk factors for postoperative CBD stone were CBD stones >2, CBD stone size >10 mm, cholesterol stone, maximum diameter of CBD >15 mm, treatment with endoscopic sphincterotomy alone, and use of endoscopic mechanical lithotripsy (EML). In multivariate analysis, cholesterol stone, CBD stones >2, CBD stone size >10 mm, and EML were related to postoperative CBD stones after cholecystectomy. Conclusions: Based on the relatively high rate of postoperative CBD stones after cholecystectomy, careful follow-up should be considered in patients with high-risk factors to detect CBD stones early.
