[Patch widening technic of benign bile duct stenosis in dogs using teflon and Solco grafts].
In 30 dogs, weighing 20 to 30 kg, the common bile duct was ligated. Pre- and postoperative bilirubin, GOT, GPT and alc. phosphatase were controlled. Eight days later a longitudinal incision was made across the stenosed segment, which was then widened with a patch. 15 dogs received a Teflon patch - 15 other dogs a Solcograft pathch. After patch-widening-plasty laboratory parameters returned to normal within a few days. X-ray controls could not find any stenosis two years after Teflon-patch-plasty, while after Solcograft-patch-plasty four dogs showed a common bile duct-stenosis within the first following year. Four weeks after Teflon-patch-plasty the patch was covered with bile duct epithelium inside. After Solcograft-patch-plasty within the first postoperative year no epithelization could be observed.
