ABSTRACT
Objective:To study the clinical features of intrahepatic biliary cystadenoma (BCA), with the aim to improve its treatment results.Methods:The clinical data and follow-up results of 86 patients with BCA treated at our department from March 2010 to January 2021 were retrospectively analyzed. Of 86 patients, there were 15 males and 71 females, with age of (48.4±13.1) years old. According to the surgical procedures carried out, 44 patients were divided into the minimally invasive group and 42 into the open group. Clinical data including imaging data, blood biochemistry, and tumor markers were collected. The follow-up data of these patients was collected in outpatient clinics or by telephone review.Results:Of 86 patients, 19(22.1%) patients had a monocystic lesion while 67(77.9%) patients had a multicystic lesion, 64 patients (74.4%) had intracapsular segregation, and 12(14.0%) patients had solid structures. Eighty-six patients with BCA were misdiagnosed as hepatic cysts in 9 patients (10.4%), hepatic echinococcosis in 2 patients (2.3%), biliary hamartoma in 1 patient (1.2%), and hepatic hemangioma in 1 patient (1.2%) before surgery. The tumor size [(6.5±3.2) vs. (9.0±4.0) cm], operative time [115(88, 185) vs. 195(160, 254) min], intraoperative blood loss [50(20, 162) vs. 300(200, 600) ml], and postoperative hospital stay [4(3, 6) vs. 8(7, 10) d] were significantly lower in the minimally invasive group than the open group. The differences were statistically significant ( P<0.05). In the 73 patients with complete follow-up, (median follow-up 63.5 months), 4 patients had developed tumor recurrence. Conclusion:Intrahepatic bile duct cystadenoma lacks specific clinical manifestations, and has a high rate of misdiagnosis and mistreatment. Early radical hepatectomy improved clinical outcomes.
ABSTRACT
Intrahepatic biliary cystadenoma (IBC) is a rare benign cystic neoplasm of liver,with malignant potential to transform into intrahepatic biliary cystadenocarcinoma.IBC predominantly occurs in women up to 85％,showing no special clinical symptoms and a polycystic lesion inside the liver on image examination.It is difficult to differentially diagnose from other cystic lesions of the liver such as simple liver cyst,intraductal papillary neoplasm of the bile duct,etc.The missed diagnosis and misdiagnosis rate were rather high in IBC,which is accurately diagnosed by pathological examination.Complete surgical removal of the tumor is the best way to cure it,and also can bring a satisfactory outcome to patients.
ABSTRACT
Objective To analyze the clinical features of intrahepatic biliary cystadenoma and cystadenocarcinoma.Methods Sixteen patients from Dec.2008 to Dec.2013 were retrospectively reviewed to investigate their clinical manifestations,image features,treatment and prognosis.Results Intrahepatic biliary systadenoma and occured occurred primarily in middle-aged women with no typical clinical manifestations.Image examination is the key method in diagnosis.Surgery is the only method to cure the disease.The procedure depends on its location,and its prognosis is related to complete surgical resection.Conclusion Intrahepatic biliary cystadenoma and cystadeno-carcinoma is a rare tumor occuring mostly in middle-aged women.Image examination is the key method in diagnosis.Complete surgical resection contributes to its better prognosis.
