[Our experience with reparative and derivative operations for non-cancerous lesions in the extrahepatic bile ducts].

17 reparative operations on the bile ducts, 7 of which were immediate (5 for peroperative lesions and 2 for "spontaneous" lesions) and 10 reoperations to deal with sclero-cicatricial lesions, were studied. 7 reconstructive operations (plastic or end-to-end anastomosis) and 10 derivative operations with a preference for hepato- or choledocho-jejunostomy on defunctionalized loop were carried out. The former were reserved for lesions without or with minimum loss of substance, the latter for extensive lesions. Operative mortality is high and higher still in immediate interventions. Long term results were good in all cases but one.
