A case that detained SEMS by the Rendezvous method for biliary tract stenosis through PTGBD route after the Roux-en-Y gastric bypasss surgery

Abstract

A 64-year-old woman underwent Roux-en-Y gastric bypass surgery for the treatment of antral obstruction due to type 3 gastric cancer. Two months later, liver dysfunction due to malignant biliary tract stenosis was noted. The endoscopic retrograde cholangiography with a double balloon endoscope (DBE) and the percutaneous transhepatic biliary drainage for biliary obstruction were unsuccsessful. Percutaneous transhepatic gallbladder biliary drainage (PTGBD) was performed,and thereafter self expanded metalic stent using DBE was successfully placed into the common bile duct with the Rendezvous technique from the PTGBD route.this Rendezvous procedure using DBE may be one of the therapeutic options for biliary obstructidon after gastric surgery.
