Abstract: 【Abstract】〓Objective〓To explore the clinical characteristics of biliary cystadenoma (BCA) and review literature. Methods〓Six cases with BCA were admitted to Sun Yat-sen Memorial Hospital from September 2009 to September 2014 and underwent surgical procedure. The Clinical manifestation, imaging feature and surgical results from six BCAs were analyzed retrospectively. Results〓All 6 patients were female, and aged from 28 to 46 years old. Chief complains were upper abdominal pain (50%, 3/6), asymptomatic examination found (33.3%,..2/6) and jaundice with fever(13.7%,..1/6). Course of disease ranged from 3 days to 16 years. No abnormal preoperative liver functions were found except the cases with jaundice and fever,..and tumor markers of all the patients showed no abnormality. Preoperative B ultrasound,..and CT examinations failed to make an accurate diagnosis, only two case were confirmed by MR...All patients underwent complete resection of the whole lesion without complication or recurrence in a follow-up duration of 3-46 months. Conclusion〓The incidence of BCA is rare and its cause is unclear. It occurs predominantly in middle-aged women with mild clinical symptoms and it is hard to make an accurate preoperative diagnosis by laboratory and imaging examinations. The final diagnosis still depends on pathological examination. Complete removal of the whole lesion is essential for BCA.
