Resolution of Intrabiliary Ruptured Hepatic Hydatid Cyst after Endoscopic Extraction: Case Report
Hepatic hydatid cyst may rupture into bile ducts in 4-20% of cases leading to cholestasis in 2/3 of cases. We tried to prove that ERCP can replace surgery in treatment of intrabiliary ruptured hydatid cyst. Our patient was 42 years old male with cholestasis, abdominal ultrasonography showed hypoechoic lesion at postero-inferior aspect of right lobe related to dilated CBD, total bilirubin 26.1 mg/ dl, direct bilirubin 18.8 mg/dl. MDCT revealed ovoid cystic lesion in right lobe, serology for hydatid was positive. Cyst was seen communicating with confluence of hepatic ducts. During ERCP, membranes were seen coming out of papilla of Vater, on injection of contrast; communication of biliary tree with cyst was established. Endoscopic papillotomy was performed and cannulation of bile duct reached abscess cavity with aspiration of yellowish green fluid, bacteriological examination of this fluid showed pseudomonas aeruginosa. Large amount of membranes were removed from CBD and sent for histopathology which showed picture of hydatid cyst. Procedure was completed with CBD stenting. Single course of Albendazole was given. Follow up after one month showed marked improvement of patient's general condition with drop of TLC and bilirubin. Follow up MDCT showed marked regression in size of previously described lesion. One month later, additional drop of bilirubin was achieved. Abdominal ultrasonography showed complete resolution of cyst confirmed by ERCP revealing start of cyst calcification with obliteration of its cavity and stent was removed. We concluded that therapeutic ERCP may replace surgery in treatment of intrabiliary rupture of hepatic hydatid cyst.
