[Therapeutical options in lithiasic biliary fistula].

Chronic lythiasic cholecystitis is a disease distinguished by the pathologic changes because of the chronic inflammation of the biliary extrahepatic tree. Sometimes these morphological changes are associated with internal biliary fistulas arising spontaneously in patients with advanced calculus cholecystitis. The vast majority of fistulas result from the adherence of the inflamed gallbladder or common bile duct to an adjacent viscus and erosion of the gallstones into the adherent organ. The authors analyze an amount of 43 patients with bilio-biliary and bilio-digestive lythiasic fistulas, caused by the long evolution of chronic lythiasic atrophic cholecystitis, for 126 cases which were operated in the Surgery Department of the Caritas Clinic Hospital along 20 years. In these 126 cases the surgical strategy was determinated by the method of dealing with the pericolecystitis sclerotic blocks, by the identification methods of the biliary elements and by the approach of the main billiary way and digestive loops injuries occurred after suppressing the fistulae. The surgical solutions adapted for each separate case and the advantages of the axial drainage of prostheting the surgical reconstructions of the main biliary way as well as the results obtained along this project, are in fact the aims of this presentation.
