In 9 out of 11 subjects with upper digestive dyspepsia: pyrosis, nausea, emesis, bloating, with negative roentgenological findings, a radioisotopic test detected a delayed gastric emptying. The investigation was based on a 500 ml saline meal including lmCi (3.7 MBq) 113m In-DTPA. For the sequential detection of the radioactivity in front of the epigastric area a gammacamera was used. This was linked to a microcomputer processing the histograms of the curves and estimating the half-time of the gastric emptying (normal value 8-25 min). The results suggest the need for prokinetic drugs in the management of symptoms due to functional pathology.

The effect of the new gastrokinetic agent cisapride on gastric emptying was evaluated in 17 dyspeptic patients using the dual radionuclide technique. Eight patients with idiopathic dyspepsia and nine postsurgical dyspeptic patients were studied and compared to a control group. Gastric emptying of solids and liquids was determined after ingestion of a standardized meal using 99mTc-sulfur colloid scrambled eggs as the solid phase and [111In]DTPA-labeled water as the liquid phase. Following a basal study and on a separate occasion, each patient received an intravenous bolus of 10 mg of cisapride after ingestion of the test meal; 10 of the patients were restudied after a two-week period of chronic oral administration of the drug (10 mg four times a day). Baseline gastric emptying of solids was significantly delayed in idiopathic and postsurgical patients; liquid emptying was only delayed in the postsurgical group. Intravenous and oral administration of cisapride significantly shortened gastric emptying in both groups. In all but one patient, the clinical improvement was confirmed by the test. Cisapride appears to be a good alternative to metoclopramide and domperiodone in the treatment of dyspeptic patients. The dual radionuclide technique appears to be a useful physiologic tool for evaluating and predicting the efficacy of a gastric prokinetic therapy in man.
