Cystic dilatation of the common bile duct in adults: report of five cases and review of literatureAbstract
The authors report five cases of cystic dilatation of the common bile duct Type I (Todani’s classification) in adults patients, in Division of General Surgery of a University Hospital, treated over a- 25-year- period from 1974 to 1999, among 16.057 operations, and not previously published. Diagnosis was obtained by operative cholangiogram (OC) in the first case, percutaneous transhepatic cholangiogram on the second one (PTHC) and by ultrasonography (US), endoscopic retrograde cholangiopancreatography (ERCP), and operative cholangiogram (OC), respectively, on the last three cases. The second patient had an adenocarcinoma arising in the cystic wall associated with peritoneal metastasis. The first two cases were treated by internal drainage and the last three by excision of the cysts and bilioenteric anastomoses. Classification, incidence, etiology, diagnosis, malignization and surgical treatment of biliary cystic disease (BCD) were revised, with the conclusion that resection must be the preferable method of treatment, when possible, especially due to the concern of malignization.
