title: A case of choledocholithiasis treated by parallel cannulation along with PTGBD rendezvous.
abstract: We herewith describe a case of choledocholithiasis, with large duodenal diverticula, endoscopically treated by the parallel cannulation method alongside the extended percutaneous transhepatic gallbladder drainage (PTGBD) tube. An 81-year-old man was admitted to hospital with complaint of abdominal pain and high-grade fever. The patient was treated by PTGBD and was referred to our institution. Endoscopic retrograde cholangiography (ERC) showed a wildly winding lower bile duct, so that we could not approach the bile duct stone at that time. Next, we extended a PTGBD tube into the duodenal lumen and stretched the lower bile duct straight. Then, the bile stone was successfully moved out through ampulla without any complication.
