An approach to the hepatic hilus with marked fibrosis: a surgical technique for reconstruction of the bile duct with a benign stricture.

It is very difficult to approach the hepatic hilus safely in patients with common and/or hepatic bile duct strictures in which normal tissue has been replaced by scarred tissue with firm fibrous adhesions. In this report, we describe how eight patients with benign strictures of the bile duct underwent an operation which involved dividing the superior mesenteric and portal veins from the lower margin of the pancreas in a dorsal direction using a finger in a tunneling technique. The common bile duct, which was buried in scar tissue, was then explored, while the common and/or proper hepatic arteries in the hepatoduodenal ligament were confirmed, after transsection at the superior margin of the pancreas. Biliary reconstruction was successfully performed after resection of the constricted bile duct in all the patients, none of whom have experienced recurrence from 6 months to 5 years after the operation.
