[Evaluation of the intensity of the duodenogastric reflux based on the alkaline phosphatase and trypsin activities in the stomach contents].

Abstract

Alkaline phosphatase and trypsin activities were measured in the gastric contents of patients with chronic gastritis with visually fixed duodenogastric reflux and without reflux. The authors discuss the advantages of a comparative approach to the enzymatic assessment of duodenogastric reflux presence, intensity, and length.
