What this Trial Is About
The BILNOR study is a prospective multicenter observational study evaluating how common bile duct stones are best managed in patients undergoing cholecystectomy. The study focuses particularly on transcystic laparoscopic common bile duct exploration (LCBDE) and assesses stone clearance, technical success, complications, and health-economic outcomes in routine clinical practice. A secondary aim is to compare LCBDE with intraoperative ERCP regarding efficacy, complication rates, and costs. Approximately 340 patients from several Norwegian centers are planned to be included starting in March 2026.
