[The clinical evaluation of a method for venous autoplasty of the extrahepatic bile ducts].

Based on previous experimental investigations, the authors have successfully performed autovenous plasty of defects of extrahepatic bile ducts for scarry strictures under clinical conditions. In 3 patients portions of conserved free autovein were used. In 3 other patients a preliminarily bougienaged dissected segment of the umbilical autovein was used. The authors consider that to use a polyethelene drainage-frame is necessary for performing the above mentioned operations during 7-8 weeks.
