Abstract
A-70-year-old man was referred to our hospital for the treatment of gall bladder stones and common bile duct (CBD) stones. Endoscopic biliary drainage (EBD) using plastic stent was performed following sphincterotomy. After laparoscopic cholecystectomy, we noticed the migration of the plastic stent into CBD and tried to remove it endoscopically through the duodenal papilla. However, the plastic stent was incarcerated just behind the duodenal papilla, thereafter it would not move despite the application of any endoscopic devices. Next day acute obstructive cholangitis occurred and PTBD was performed. To release the plastic stent from the biliary wall, we employed the AMPLATZ GOOSE NECKTM Microsnare Kit through the PTBD route. After the successful release, we retrieved the plastic stent endoscopically from the duodenal papilla. Specific devices for removing foreign bodies of CBD are not available because such a case is rarely encountered. The AMPLATZ GOOSE NECKTM Microsnare Kit is a very useful device. Due to a thin caliber, it can be safely applied to even bleeding tendency patient through the small number of PTBD catheter exchange.
