Bilomas: a new approach to the diagnosis and treatment

Biloma, a newly described entity, appears to have gained a heightened clinical interest recently. During the past 18 months we have diagnosed 9 abnormal biliary collections. We discuss here the role of sonography and radionuclide cholescintigraphy in the evaluation of bilomas. The diagnosis of all cases was confirmed by ultrasound-guided percutaneous needle aspiration. Subsequently 7 patients were treated with catheter drainage, obviating the need for any surgery.
