technetium-tc-99m-disofenin and Intestinal-Perforation

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.

During the intestinal phase of hepatobiliary imaging studies in four patients, unusual small intestinal abnormalities were noted. These findings were correlated with surgery in three patients. Recognition of these patterns gives additional clinical information of significant diagnostic value. Further attention to small intestinal pattern and/or radionuclide evaluation of small intestine is a promising method of noninvasive evaluation of clinically suspected small intestinal infarction and obstruction.
