Spontaneous biloma managed with endoscopic retrograde cholangiopancreatography and percutaneous drainage: a case report

Abstract

IntroductionSpontaneous biloma formation is a very rare condition, which mandates immediate treatment.Case presentationAn 80-year-old Caucasian man was referred to our department with a diagnosis of intra-abdominal collection located in his right upper quadrant. Further radiological examination demonstrated multiple calculi in his gallbladder and common bile duct. Our patient underwent endoscopic retrograde cholangiopancreatography and the stones in the common bile duct were extracted. Percutaneous drainage of the abdominal collection revealed a spontaneous biloma formation. Continuous drainage of bile persisted for one week, so endoscopic retrograde cholangiopancreatography was repeated and a 10Fr stent was placed; subsequently the biliary leak ceased and our patient was discharged. A control abdominal computed tomography did not show any residual fluid collection.ConclusionSpontaneous biloma formation is a very rare incidence; awareness is necessary for prompt recognition and treatment.

An Unexpected Complication in a Pediatric Patient With Sclerosing Cholangitis: A Huge Spontaneous Biloma

“…The necessary imaging methods for the diagnosis of the biloma are ultrasonography, computed tomography, MRI and MRCP. ERCP can be used for both diagnostic and therapeutic purposes [11]. Our case presented with abdominal distention and pain, but her biloma was misdiagnosed as massive ascites on the first abdominal ultrasonography.…”

Management Of Localised Postoperative Bile Collections

“…The most frequent cause of spontaneous biloma is choledocholithiasis; very rare are neoplasms of biliary tree, acute cholecystitis, hepatic infarction or abscess, obstructive jaundice and tuberculosis [6].…”

Etiology, Diagnosis, and Management of Bilomas: A Current Update

“…2 An association between bilomas and pancreatic cancer has also been described. 17,18 Bilomas have been reported to complicate sickle cell disease, likely as a consequence of hepatic infarction. 19,20 …”
