[Surgery of operative lesions of the principal biliary passages]

The authors present their experience acquired in 30 cases of surgical interventions performed for the correction of accidental lesions of the main biliary pathway. The essential parameters are discussed in this paper, which determine the degree of difficulty of the corrective interventions. Indications are also discussed concerning tactical and technical aspects depending on the level of the lesion, as well as in relation with its type. The authors present some particular aspects of prostheses used in the derivations which they have made with a corrective purpose.
