Postviral gastroparesis: presentation, treatment, and outcome

We describe the clinical features and long-term outcome of 11 children who had persistent gastroparesis after an acute viral illness, eight of whom tested positive for rotavirus. Gastric emptying was delayed in the 10 children evaluated with scintigraphy. Antroduodenal manometry confirmed postprandial antral hypomotility in 10 subjects. All children recovered within 6 to 24 months.
