Gallbladder Hydatid Disease Complicated with Multiple Hepatobiliopancreatic Fistulae: A Case Report

Gallbladder is a rare localization for hydatid disease. Complications are even rarer and precise diagnosis is quite difficult even with radiological assistance. We report a rare case of 41-yr-old male patient presenting with the rupture of a gallbladder hydatid cyst with multiple fistulae to intra and extrahepatic bile ducts and pancreas, at Kocaeli State Hospital, Turkey in 2021. The patient had abdominal pain and abdominal CT scan reported a bizarre “contrast enhanced cholangiography” sign - radiopaque contrast substance in gallbladder, intra and extrahepatic bile ducts and pancreatic ducts, with concomitant acute cholecystitis. Surgery was performed and intraoperatively gallbladder hydatid cyst with multiple fistulae was noted. Cholecystectomy with total cyst excision was performed. Endoscopic retrograde cholangio pancreatography (ERCP) was utilized to irrigate and eradicate the parasite in the fistulae tracts localized near pancreas and intra/extrahepatic ducts. Postoperative period was uneventful, antiparasitic treatment was started, and in the yearly follow-up patient had no recurrence. Multidisciplinary and minimal invasive management is crucial in such bizarre, complicated cases.
