[Bile leakage, bile ascites and bilioma--nuclear medicine diagnosis--demonstration of typical cholescintigraphic findings].

Cholescintigraphy (hepatobiliary sequential scintigraphy) with 99m Tc-marked IDA derivatives results in a specific identification of bile in free intraperitoneal fluids (bile ascites) or encapsulated intraperitoneal fluids (bilioma). To detect or exclude a biliary leak, cholescintigraphy was performed in 42 patients. In contrast to sonography and CT ("anatomical imaging"), which are capable of detecting an intraperitoneal accumulation of fluid with high sensitivity, cholescintigraphy ("functional imaging"), alone can help to identify the presence of bile in such fluids, both specifically and on a non-invasive basis. Modern gamma cameras are of such high sensitivity that they can identify even the most minute of activity (bile) quantities with satisfactory anatomic allocation.
