[Transduodenal papillotomy and divulsion of the papilla in the treatment of benign obstructions of the common bile duct (retrospective analysis of 186 cases)].

An analysis is presented of 186 cases of biliary benign obstruction, treated with transduodenal sphincterotomy or dilatation-divulsion of the papilla of Vater. The morbidity and mortality rates due to specific complications were 5.4% and 1.6% respectively. No cases of post-operative pancreatitis were observed. Long-term results were re-evaluated in 46 patients after a mean post-operative interval of 18 years. The follow-up demonstrated that the result was completely satisfactory in 70% of cases; fair in 17%, with gastroenterological symptoms not likely related to the biliary disease; poor in 13%, with residual stones or stenosis of the sphincter of Oddi.
