Intractable biliary obstruction after TIPS creation treated by magnet-assisted endoscopic biliary-duodenal anastomosis



Though biliary obstruction is a common clinical situation, it is rarely caused by transjugular intrahepatic portosystemic shunt (TIPS) placement. When TIPS-induced intractable biliary obstruction happens, liver transplantation seems to be the only resort to cure this condition.


Herein, we describe a patient who suffered from intractable biliary obstruction following TIPS placement.


The patient was finally cured by magnet-assisted endoscopic biliary-duodenal anastomosis, without further requirement of liver transplantation. After more than 6 months of follow-up, this patient recovered well, and recurrence of biliary obstruction was not observed.


We showed that magnet-assisted endoscopic biliary-duodenal anastomosis is a safe method, which is easy to perform and worthy of popularizing.

Choledochoscope was introduced via PTCD fistula after removal of 20fr tube to advance an 8 mm magnet into biliary duct. After identification of the narrowing of bile duct and a site of duodenal wall, where was closest to the narrowing, a 10 mm string-attached magnet was placed to the site by endoscope. Finally, the magnets were allowed to align together during endoscopy. Supplementary file1 (AVI 78454 kb)
