title: Percutaneous liver biopsy complicated by hemobilia-associated acute cholecystitis.
abstract: Liver biopsy is generally considered a safe and highly useful procedure. It is frequently performed in an outpatient setting for diagnosis and follow-up in numerous liver disorders. Since its introduction at the end of the 19th century, broad experience, new imaging techniques and special needles have significantly reduced the rate of complications associated with liver biopsy. Known complications of percutaneous biopsy of the liver include hemoperitoneum, subcapsular hematoma, hypotension, pneumothorax and sepsis. Other intra-abdominal complications are less common. Hemobilia due to arterio-biliary duct fistula has been described, which has only rarely been clinically expressed as cholecystitis or pancreatitis. We report a case of a fifteen year-old boy who developed severe acute cholecystitis twelve days after a percutaneous liver biopsy performed in an outpatient setting. The etiology was clearly demonstrated to be hemobilia-associated, and the clinical course required the performance of a laparoscopic cholecystectomy. The post operative course was uneventful and the patient was discharged home. Percutaneous liver biopsy is a safe and commonly performed procedure. However, severe complications can occasionally occur. Both medical and surgical options should be evaluated while dealing with these rare incidents.
