Demonstration of traumatic bile leakage with cholescintigraphy and ultrasonography

Technetium-99m HIDA cholescintigraphy and ultrasonography are noninvasive, safe, simple procedures that can document the presence, location, and extent of a bile leak. Early detection of posttraumatic or postoperative biliary tract disruption can significantly reduce morbidity and mortality. The possibility of biliary tract disruption should be considered in any patient who has had blunt or penetrating abdominal trauma. In two cases reported, the new hepatobiliary radiotracer 99mTc dimethyliminodiacetic acid (HIDA) was quite useful in detecting such leaks. Sonography was particularly useful in detecting small intra- or perihepatic bile collections which no longer communicate with the biliary tree. An active bile leak at a surgical anastomosis may also be documented by 99mTc-HIDA cholescintigraphy and can yield information of potential prognostic importance. Serial cholescintigraphy is also useful in evaluating the response to medical or surgical treatment.
