The most major cause of hilar bile duct stenosis is the malignant disease, but there are some benign causes and that makes the differentiation very difficult. We experienced a case of chronic cholecystitis to case a hilar bile duct stenosis which was difficult to differentiate from the gallbladder cancer.
We performed contrast CT (Computerized Tomography), ERCP (Endoscopic Retrograde Cholangiopancreatography), EUS-FNA (Endoscopic Ultrasound-Fine Needle Aspiration), PET CT (Positron Emission Tomography CT). From the results of these inspections, we diagnosed the case as chronic cholecystitis and operated a laparotomy cholecystectomy. The pathological diagnosis was chronic cholecystitis, and that showed we could raise the probability of diagnosis by performing some inspections and we could avoid the enlarge operation of liver resection. In conclusion, we recommend to combine some inspections before having the operation of hilar bile duct stenosis.
