Abstract
|
|
|
Biliary cystic neoplasms are rare tumors arising primarily in the liver. We studied the clinical and pathological features, surgical management, and follow-up results of 6 patients with biliary cystadenoma(BCA) and 3 patients with biliary
cystadenocarcinoma(BCAC) who were surgically treatcd over an 11-year period. The mean age of the BCA and BCAC patients was 44 years and 53 years respectively. All of the 6 BCA and 1 of the 3 BCAC patients were female. The most common presenting
symptoms
and signs were abdominal discomfort and a palpable abdominal mass. Serum CEA and alpha fetoprotein were not elevated in any of the cases. The Clonorchis sinensis ova were found in one of 6 BCA and 2 of 3 BCAC patients. The size of the cysts
varied
from
7to 30cm and all cysts except one were multiloculated. Nodulr thickening in the internal septa was found only in BCAC. All of the BCA cases had mesenchymal stroma resembling ovarian stroma resembling ovarian stroma. In BCAC, foci of benign
epithelium
was found. Two BCA and one BCAC patient had biliary connections, multiple connections were found only in the latter. Two patients who underwent marsupialization had a later recurrence. No patients experienced recurrence after complete excision.
In
conclusion, complete excision is recommended in BCA and BCAC. Multiple connections found in one BCAC patient suggest that BCA and BCAC develop from a nest of embryonic bile duct.
