Core tip: The number of females was larger than that of males in both groups. Carbohydrate antigen 19-9 has important significance in the preoperative diagnosis of intrahepatic biliary cystadenoma and cystadenocarcinoma. About half of the patients had elevated levels of total bilirubin (TBIL) and direct bilirubin (DBIL); therefore, we believe it is necessary to test TBIL and DBIL before surgery. The diagnosis relies on the integration of information consisting of clinical symptoms, laboratory findings and imaging results. The short-term and long-term prognoses of cystadenoma were better than those for cystadenocarcinoma.
