[Anatomoclinical and therapeutic considerations on non-lithiasic benign papillo-oddian stenosis]

Based on their personal experience involving 19 cases of benign, non-lithiasic stenoses of the Oddi sphincter (in a total of 2,500 interventions on the cholecyst and the choledocus), the authors review the etiopathogenic, diagnostic and therapeutic aspects. The difficulty is stressed, encountered in evaluating the reversibility of these lesions and the codification of the therapeutic attitudes.
