Cholescintigraphy in the diagnosis of duodenogastric reflux in children, preliminary report.

The gastroduodenal reflux is considered, to be one of the important factors in the pathogenesis of gastritis and gastric ulcers. Endoscopic features suggesting bile reflux are not fully objective and may be a reason for false diagnosis of gastroduodenal reflux. The following study was established to verify the endoscopically diagnosed bile reflux by a scintigraphical test. In 30 of the 350 patients we showed bile reflux endoscopically, but 21 of them had duodenogastric reflux confirmed by cholescintigraphy. The autors maintain that cholescintigraphy seems to be a very useful method in the proper diagnosis of bile reflux.
