A simple method for biliary‐enteric anastomosis and chronic bile diversion in the rat

A simple method of biliary‐enteric anastomosis, without the use of surgical microscopy, is described. There were no signs of cholestasis after 3 mo of follow‐up. A modified procedure using a silicone elastomer catheter as a stent for the biliary‐enteric anastomosis resulted in biliary obstruction within 3 wk after surgery. Our experimental bile duct implantation technique is a simple and useful experimental method for the investigation of chronic biliary diversion and biliary physiology. Additionally, it can be performed safely and easily in a rodent model without sophisticated microscopic techniques. (HEPATOLOGY 1991;14:128–130.)
