Analysis on the anatomic features of 47 cases of hepatic hydatidosis complicated with biliary fistula

Objective To propose a criterion and its significance of clinical classification of hepatic hydatidosis complicated with biliary fistula. Methods 47 hepatic hydatidosis with biliary fistula cases who were given a sub-adventitial pericystectomy were observed from 2000 to 2005 in a retrospective study. The methods included observation of the different anatomic features of hepatic hydatidosis complicated with biliary fistula during the surgical operation and evaluation of the curative effect. Results All the 47 patients recuperated successfully and had no complication. Based on the anatomic features of hepatic hydatidosis complicated with biliary fistula,a criterion on clinical classification was proposed as three types: tangential,transfixional and terminal types. Conclusions Hepatic hydatidosis complicated with biliary fistula can be classified as three types according to its anatomic features.
