PurposeThe rupture of the hydatid cyst into the bile ducts is a common and serious complication. The rupture can be latent or revealed after a complication such as acute cholangitis. The objective of this study was to discuss the clinical features, radiographic findings, and surgical treatment of this rare complication.MethodsA retrospective analysis of patients operated for acute cholangitis caused by hydatid cyst between January 1990 and May 2016 was conducted.ResultsOur study included 55 cases of acute cholangitis caused by ruptured hydatid cyst: 35 were men and 20 were women. Five patients had medical history of hydatid cyst. On imaging, all patients had a dilated bile duct. In 51 cases, there was a single hydatid cyst. Hydatid cysts with fistula were located in the right lobe of the liver in 49 cases and in the left lobe in 6 cases. Seven patients underwent an emergency surgery after admission, while others were operated after 3-8 days. A conservative procedure associated with drainage was applied in 49 cases. Endoscopic treatment was performed in four cases which failed in two cases. Twenty-eight cases developed postoperative complications, among which the most common complication was biliary fistula (n - 17). There were eight cases of postoperative deaths (14.5%).ConclusionsLiver hydatid cyst with cystobiliary communication and superadded acute cholangitis is a serious clinical problem requiring the early diagnosis and surgery in the absence of endoscopic therapy.
