Percutaneous retrieval of a proximally migrated common bile duct endoprosthesis from the right anterior duct

Common bile duct (CBD) endoprostheses that are inserted at endoscopy are in routine clinical use to decompress the obstructed biliary tract. This case describes the proximal migration of a CBD endoprosthesis into the right anterior duct. An attempt at endoscopic retrieval failed. The endoprosthesis was retrieved by a percutaneous transhepatic approach using an Amplatz goose‐neck snare. To the best of our knowledge, use of the Amplatz goose‐neck snare has not been reported for this application.
