[Acquired abnormalities of the biliary tract. Preoperative diagnosis and surgical risk in the laparoscopic era].
Acquired anomalies of the biliary tract are rare. The aim of this work was to examine their frequency and to assess potential associated danger when performing a laparoscopic cholecystectomy. A retrospective analysis of clinical charts of 3.870 patients undergoing elective cholecystectomy between 1959 and 1997 was performed. Eighteen cases of choledoco-duodenal fistula, 9 of cholecysto-duodenal and 12 of cholecysto-choledochal fistulas were observed. Two cases of acquired absence of the cystic duct and one cholecysto-colic fistula were also encountered. The traditional contrastographic radiology showed to be more accurate in defining presence and nature of the acquired anomalies. Etiopathogenesis of the main anomalies and consequent risks in performing laparoscopic cholecystectomy were discussed.
