Analysis of diagnosis and treatment of intrahepatic biliary cystadenoma / 中国普通外科杂志

ABSTRACT

Objective To improve the recognition of intrahepatic biliary cystadenoma.Methods The clinical manifestations,radiologic features,diagnosis and surgical treatment of 18 patients with intrahepatic biliary cystadenomaadmitted in our hospital during the recent 8 years were retrospectively analyzed.Results Four cases were discovered by general medical examination,while the other 14 patients had varying symptoms that included right upper abdominal discomfort or pain in 11 cases,abdominal mass in 3 cases,and jaundice accompaniedby fever in 2 cases.B ultrasound and CT scan showed intrahepatic cystic occupying lesions consistingof multilocular or single cyst,and usually with papillary structures in the cyst wall.All of 18 cases received surgical resection.The patholgic dingnosis was intrahepatic biliary cystadenoma in all the 18 cases,and 6 of them showed malignant change.The average survival time of maligmant patients was 35(27-58)months.Conclusions Preoperative diagnosis of intrahepatic biliary cystadenoma is difficult.Intrahepatic biliarycystadenoma is easy to develop into cystadenocarcinoma.Early surgical resection is necessary,and can effectively prevent recurrence or malignant transformation.
