BACKGROUND: Endoscopic sphincterotomy is difficult and sometimes impossible in patients who have undergone gastrectomy or partial gastrectomy with Billroth II reconstruction. For such patients, a novel technique was developed in which endoscopic sphincterotomy is performed via percutaneous transhepatic cholangioscopy. This report describes an initial experience with this technique.
METHODS: After dilation of the percutaneous fistula, a cholangioscope with a push-type sphincterotome attached was inserted into the bile duct via the fistula and then through the papilla into the duodenum. The tip of the instrument then was retroverted to obtain a frontal view of the papilla. Then, a sphincterotomy incision was extended to the proximal, orad margin of the papillary eminence.
OBSERVATIONS: Percutaneous transhepatic biliary drainage was performed in 3 patients with obstructive jaundice and bile duct stones. In all patients, percutaneous transhepatic cholangioscopic sphincterotomy was performed successfully, without procedure-related complication. Thereafter, all stones and stone fragments cleared from the duct by spontaneous migration.
CONCLUSIONS: Endoscopic sphincterotomy via percutaneous transhepatic cholangioscopy potentially is an innovative technique for endoscopic sphincterotomy in patients with an endoscopically inaccessible papilla.
