위암 환자에서 위절제술후 나타나는 담도확장의 임상적 의의: 추적 CT 소견을 중심으로

Abstract

A retrospective review of consecutive 35 patients'pre and post operative abdominal computed tomography was performed to determine frequency and degree of bile duct dilatation following Billroth Ⅱ operation for stomach cancer and it's clinical significance.

Degree of intrahepatic biliary dilatation was classified as mild, moderate, marked according to the extension into central, middle and peripheral zone of liver, respectively. Three specialists on the abdominal image participated in analysis of those findings without prior information of the patients. Intrahepatic biliary dilatation was seen in 22 patients(63%) analysed by at least one radiologist, in 13 patients(37%) by at least two radiologists. Bile duct dilatation on CT was common finding and not necessarily meant tumor recurrence. Vagotomy and afferent loop resulted form Billroth Ⅱ were one of possible causes of bile duct dilatation. This study showed in the cases of bile duct dilatation without clinical and other radiological evidence of recurrence, no further study are needed and only enough to follow up study.
