Tailored access to the hepatobiliary system in post-bariatric patients: a tertiary care bariatric center experience.

This case series indicates that ERCP via a transgastric approach (LA-ERCP, EDGE, or HGS) is a minimally invasive, effective, and feasible method to access the biliary tree in bariatric patients. These techniques offer an appealing alternative treatment option compared to percutaneous transhepatic cholangiography and drainage- or deep enteroscopy-assisted ERCP. In bariatric patients who earlier had a cholecystectomy, EUS-guided techniques were the preferred treatment options for biliary pathologies.
