[Use of alloplastic material on the extrahepatic bile ducts].
Dogs (20 kg body weight) were laparotomized and the choledochous duct was ligated. Pre- and postoperative laboratory-parameters such as bilirubin, GOT, GPT, and alcaline phosphatase were controlled. Then, 8 days later, a patch-widening-plasty was performed after incision of the stenosis in 10 dogs. In the 10 other dogs the stenosis was resected and the defect was bridged over with a Teflon prosthesis. A few days later laboratory parameters became normal. Histologic investigation showed that after 4 weeks the Teflon prosthesis was covered with a bile duct-epithelial layer. In one of 3 patients with normal laboratory findings who have a Teflon patch, the operation took place 2 years ago.
