A new approach to the measurement of gastric emptying quantifies the arrival in the duodenum of nonabsorbable markers given with test meals. The method is compared with the standard serial test meal technique in which emptying is measured by aspiration of the stomach after varying intervals of time and shown to yield similarities. The half time of gastric emptying by both methods is also similar. The proposed method has certain advantages over those used before: kinetics of gastric emptying can be ascertained from one test meal, the need for gastric aspiration can be obviated, duodenal control of gastric emptying can be studied more directly, and secretion, absorption, and transit can be studied simultaneously.
