The impact of solid-phase gastric emptying studies in the management of children with dyspepsia.
Information on the utility of solid-phase gastric emptying studies (SPGES) in the evaluation of children with symptoms of upper gastrointestinal (GI) motor dysfunction is limited. This study was conducted to evaluate the impact of SPGES in the clinical management and outcome of children with upper GI symptoms suggestive of gastroparesis. The records of 45 children who underwent SPGES (31F; 3-17 years) were reviewed. All patients had GI symptoms suggesting gastroparesis. Patients were fed with Tc-99m-sulfur colloid-labeled chicken liver. Adult normal half-life (T1/2) values (F 103 +/- 14 minutes; M 66 +/- 13.6 minutes) were used. The relationships among symptoms, treatment, and outcome were evaluated. Of the 45 patients 9 had delayed, 16 had rapid, and 20 had normal gastric emptying. Six of 9 patients with delayed gastric emptying responded to cisapride. Four of 16 patients with rapid emptying were diagnosed with the dumping syndrome. Of the children with rapid gastric emptying, 87% were females. Twenty patients with normal emptying were diagnosed with gastroesophageal reflux (8), nonulcer dyspepsia (5), irritable bowel syndrome (2), Helicobacter pylori (1), lactose intolerance (1), eosinophilic gastroenteritis (1), duodenitis (1), and constipation (1). In patients who had SPGES for possible gastroparesis, 20% had gastroparesis, 36% had rapid gastric emptying, and 44% had normal gastric emptying. The high number of females in the rapid gastric emptying group might be secondary to normal adult female T1/2 values that were used. The practice of using adult normal T1/2 values in prepubertal girls may need to be revised. Patients with delayed gastric emptying responded to cisapride.
