The aim of this retrospective, register-based study is to investigate whether access, or no access, to endoscopic retrograde cholangiopancreatography (ERCP) at a surgical unit is associated with the risk of complications in patients undergoing laparoscopic cholecystectomy with common bile duct stones detected on intraoperative cholangiography.

Patients, ≥18 years old, undergoing laparoscopic cholecystectomy with CBDS detected on IOC in Sweden 2015-2025 and registered in GallRiks. The cholecystectomy is performed in a unit without access to ERCP.
