Abstract
Laparoscopic findings on congenital dilatation of intrahepatic bile duct were described. A 65-year-old woman was admitted to our hospital because of suspected gall stones and cancer. Ultrasonographic examination, computerized tomography and celiac angiography revealed no definite evidences of malignancy in the gall bladder. On laparoscopy gall bladder was seemed to have normal appearance, but whitish small elevated lesions were observed locally on the surface near the edge of the right lobe of the liver. These elevated lesions had irregular surface and meadering appearance without central umbilication. Atypical cells were present on the biopsy specimen from the elevated lesions. The patient underwent surgical intervention. Operative cholangiography showed dilatation of the intrahepatic bile duct which corresponded to the lesions on laparoscopy. The elevated lesions were easily resected, and cut surface of the resected specimen showed several number of bile ducts, further after cutting the specimen fluid like bile juice was shedding. Clinical features and histology of the resected specimen strongly supported that the lesions were congenital origin. Reports on the laparoscopic findings of congenital dilatation of intrahepatic bile duct were few in number, therefore, the laparoscopic findings of our case was considered to be suggestive.
