Peribiliary cysts are cystic dilatations of the peribiliary glands that are located exclusively in or around the hepatic hilum. A case of peribiliary cysts that caused a hilar bile duct stenosis is presented.
A 72-year-old man had elevated liver enzymes. Radiologic examinations revealed a hilar bile duct stenosis, where cholangioscopy showed an elevated nodular lesion. Cholangiocellular carcinoma was suspected preoperatively. A laparotomy disclosed multiple small cysts in the hepatic hilum. Resection and de-roofing of the cysts were performed, and the stenosis of the bile duct was attenuated. The postoperative course was uneventful.
Peribiliary cysts are often small in diameter, so it is difficult to distinguish these cysts from dilated bile ducts or edema of portal tracts if bile duct stenosis is present. It is important to recognize that peribiliary cysts might induce bile duct stenosis.
