A case of transpapillary removal of choledocholithiasis using a forward-viewing scope by the rendezvous method via the PTGBD route

Le résumé fourni par la source

A 75-year-old woman was referred to our department to be investigated for liver damage. Abdominal computed tomography findings revealed choledocholithiasis with an 11-mm stone. We attempted endoscopic lithotomy using a duodenoscope. However, it was impossible to pass the duodenoscope beyond a gastric deformity with duodenal ulcer scar. The intrahepatic biliary duct was not dilatated, so we performed percutaneous transhepatic gallbladder drainage (PTGBD). Although we attempted percutaneous removal of the stone via the PTGBD route, this was difficult due to the steep angle of the cystic duct junction. We finally succeeded in removing the stone by the rendezvous method via the PTGBD route, as a forward-viewing scope could reach the papilla of Vater. The rendezvous method via the PTGBD route was an effective option for a patient with choledocholithiasis.
