Management for extrahepatic bile duct injury complicating with laparoscopic cholecystectomy - An experience of the magnetic compression anastomosis between the common bile duct and the duodenum

We tried choledochoduodenostomy using magnets interventionally for a case with complete obstruction of the common bile duct (CBD) after the laparoscopic cholecystectomy (Lap-C). Choledochoduodenostomy using magnets was done after 6 months later of the Lap-C. A pillar magnet of 4 mm diameter and 9 mm length was delivered at the obstructed CBD through the percutaneous transhepatic biliary drainage rout that was dilated to 14 French size. And a pillar magnet of 5 mm diameter and 5 mm length was delivered at the bulbus of the duodenum using peroral endoscopy. Anastomosis between the CBD and the duodenum was formed gradually by the force of compression between the both magnets. Two weeks later, the anastomosis was formed, there is no harmful event. Magnetic compression anastomosis is very useful for the biliary complications (stenosis or obstruction) after the Lap-C.
