Spontaneous Biloma Caused by Pancreatic Cancer and Treated by Endoscopic Biliary Stenting / 대한소화기내시경학회지

ABSTRACT

Biloma is a rare disorder, and is defined as an abnormal extrahepatic or intrahepatic collection of bile within a defined capsular space. The common causes of biloma are iatrogenic and trauma. Spontaneous biloma, especially caused by pancreatic cancer, is very rare. An 86-year-old man was admitted with abdominal pain and fever. The patient denied a history of abdominal surgery, endoscopic retrograde cholangiography, or trauma. Abdominal computed tomography demonstrated a huge collection of fluid in the left lobe of the liver, dilatation of the intra and proximal common bile duct, and a heterogeneous enhancing mass in the pancreatic head portion. Percutaneous drainage under ultrasound guidance was performed, and the fluid analysis was compatible with biloma. A plastic stent was endoscopically inserted into the common bile duct to treat continuous drainage of the fluid despite percutaneous drainage. We report a case of biloma developed spontaneously in a patient with pancreatic cancer and successfully treated by endoscopic biliary stenting.
