title: [Odditis. Pathologic reality or tactics necessity].
abstract: In 14 patients with secondary odditis, a biopsy of the papilla was studied, in one case encountering moderate peri and intrafascicular fibrosis and in another, erosion of the papillary mucosa with impaction of biliary material. In 6 biopsies obtained from patients with perforated liver cysticerocosis, submucosal edema of the biliary tree was observed in only 3. On the basis of these studies an analysis is made of the different percentages published, which are highly variable, and results are compared to those reported in larger series. Papillary affectation in lithiasis was related to trauma produced by impaction or expulsion of calculi and the indications for realization of sphincteroplasty or biliodigestive derivation are listed, showing a tendency toward a progressively greater restriction of surgery. The absence of sphincter disease in hepatic cysticercosis perforated into the biliary tract is signalled, the only alterations being edema, which is reversible with treatment of cysticercosis.
