Percutaneous cholangioscopic bilioenterostomy for unreconstructed segmental bile duct after hepatobiliary resection for hilar cholangiocarcinoma

During a major hepatectomy, inadvertent Ligation of the major segmental bile-duct branch of the liver remnant is a serious complication, We experienced this serious complication of inadvertent ligation of the bile-duct branch, which should be anastomosed to the jejunal loop, during a left hepatic trisegmentectomy with total caudate lobectomy for a hilar cholangiocarcinoma. A percutaneous transhepatic bilioenteric connection was then created, modifying an endoscopic ureteroneocystostomy technique, between the ligated segmental bile duct and the jejunal loop, In this procedure, we used two cholangioscopes; one was introduced through the percutaneous transhepatic drainage route, the other was introduced through an enterostomy which was made during the surgery for postoperative enteral feeding; we also used a transjugular intrahepatic portosystemic shunt (TIPS) kit under fluoroscopic guidance. We present here our technique of percutaneous transhepatic bilioenterostomy.
