[Reconstruction of benign biliary tract stenoses. Experimental experience with autologous and heterologous transplants (author's transl)].

A pedicled autologous jejunum transplant and a free bovine collagen prosthesis were tried for the treatment of short, benign stenoses of the bile duct in animal experiments. In both cases at follow-up periods of 6--18 months an unrestricted flow of bile was recorded in the plastically dilated bile duct macroscopically, radiologically and by the chemical laboratory. On the basis of these results in animal experiments, 3 patients were treated with a pedicled jejunum transplant for the correction of short benign stenosis of the bile duct following previous cholecystectomy. All the patients are free from complaints after observation periods of 6 months, 1 year and 2 1/2 years.
