A Case of Posttraumatic Biloma / 대한소화기내시경학회지

ABSTRACT

Biloma is defined as an extraductular collection of bile within a defined capsular space. Biloma usually occurs secondary to traumatic or iatrogenic injury including abdominal surgery, percutaneous catheter drainage, and transhepatic cholangiography. The diagnostic methods include clinical history and physical examination, abdominal ultrasound, abdominal CT scan, hepatobiliary scintigraphy, endoscopic cholangiography and percutaneous aspiration, Though definite treatment by percutaneous radiographic catheter drainage and endoscopic drainage with sphincterotomy are now feasible in many instances, surgical drainage is often needed. We report a case of posttraurnatic biloma which was developed after car accident. Liver scan and endoscopic cholangiography showed typical features of biloma in this patient.
