Hepatic subcapsular biloma. An unusual complication of endoscopic retrograde cholangiopancreatography.

Development of an intraabdominal bile collection (biloma) usually occurs secondary to traumatic or iatrogenic injury including abdominal surgery, percutaneous catheter drainage, and transhepatic cholangiogram. We present a case of hepatic subcapsular biloma following endoscopic retrograde cholangiography and identified by ultrasound and computed tomodensitometry examinations. A percutaneous drainage procedure allowed a subsequent endoscopic retrograde cholangiopancreatography to be performed that documented the location and extent of the bile leak and led to resolution of the biloma.
