A 64-year-old woman with dull pain in the right hypochondriac region was diagnosed as having a progressive simple liver cyst, 13 cm in diameter. After percutaneous transhepatic cyst drainage, the liver cyst was found to communicate with the intrahepatic bile duct. More than 400 ml/day bile was continuously removed via a percutaneous drain, and injection of minocycline hydrochloride (200 mg/day×7days) into the cyst was ineffective. ENBD (endoscopic naso-biliary drainage) was performed to decrease the inflow of bile from the bile duct into cyst, and minocycline was injected in the same method as before. Approximately 1 week after the injection, the percutaneous drain and ENBD tube were removed. Ten months after the therapy, CT scan revealed that the size of the liver cyst remained reduced. This is the first report of a simple liver cyst with biliary communication successfully treated with ENBD.
