Enterogastric reflux occurs in normal and abnormal conditions. When pronounced, it is a nonspecific indicator of pathology. There are relatively few published reports discussing enterogastric reflux as a prominent finding on cholescintigraphy. A unique case of pronounced enterogastric reflux from an obstructing duodenal hematoma is presented.

Complete reflux of duodenal contents into the stomach with persistent retention on hepatobiliary scintigraphy or radionuclide gastrointestinal bleeding studies is a relatively rare occurrence. Two cases of complete duodenogastric reflux are reported: one case in a patient with a perforated duodenal diverticulum and the other in a patient with an inflamed, bleeding duodenal ulcer. The finding of complete duodenogastric reflux and persistent retention in the stomach should instigate a thorough evaluation for significant duodenal pathology.
