ABSTRACT

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.
