Abstract
A 57-year-old female was admitted to the hospital 5 years after cholecystectomy with the chief complaints of abdominal pain and nausea.
Upper gastrointestinal series showed a smooth filling defect in the descending limb portion of the duodenum. Upper GI scope's diagnosis was duodenal polyp. The patient underwent re-operation. The duodenum was opened and the orifice of the common duct was covered by a small tense cyst. The cyst was punctured and full of bile. The diagnosis of choledochocele was made and the duodenal luminal portion of the cyst was excised. The patient was kept under observation for one year. She had no recurrence of pain or nausea.
Choledochocele is a very rare disease. There was only 4 cases in Japanese literatures.
