Incidence and risk factors of biliary fistulation from a hepatic hydatid cyst in clinically asymptomatic patients

Abstract

Biliary fistulation from a hepatic hydatid cyst is its most frequent complication. If unrecognised, this may cause difficulties during and after surgical intervention. Our study looked into its incidence and also the possible risk factors in a retrospective investigation of 60 patients (34 women) who had undergone surgery or percutaneous treatment. Demographics and anatomical characteristics, such as cyst type, location, number, diameter and laboratory findings were examined. A full 50% had biliary fistulation, with increased risk if the cyst diameter was ≥8.8 cm.
