Brief summary: Children with a radionuclide gastric emptying test with abnormal results will undergo a second test with the addition of a weight adjusted dose of monosodium glutamate. The purpose of the study is to determine if a single dose of monosodium glutamate can shorten the gastric emptying time.

Detailed description: There is evidence that monosodium glutamate has effects on synapsis at the gastric and duodenum level that results in stimulation of contractility resulting on increase rate of gastric emptying. The purpose of the study is to demonstrate that the administration of a single dose of monosodium glutamate can shorten the gastric emptying time.

Patients with a prior study indicating a delay of gastric empting time, will undergo a second test with the addition of a weight adjusted dose of monosodium glutamate. Each patient will serve as her/his own control. Results will be analysed by pair-T test.

Eligibility criteria: Inclusion Criteria:

* children with delayed gastric emptying not receiving prokinetic medication in the last 72 hours

Exclusion Criteria:

* Prior gastrointestinal surgery, patients with known history of reaction to monosodium glutamate. History of neoplasia, autoimmune or inflammatory bowel disease.

Primary outcomes:
measure: Reduced gastric emptying time
timeFrame: During the test (4 hours from intake)
