We experienced a 15 month old child who had persistent gastroparesis after an acute viral illness tested positive for rotavirus. She was admitted because of persistent postprandial vomiting, abdominal distension and anorexia followed after acute rotavirus gastroenteritis. Other diagnostic tests did not demonstrate any evidence of some organic disease. But, we could find the delayed gastric emptying in gastric scintigraphy. The initial percentage gastric emptying in 60 minutes tested by scintigraphy was 13.4%. The second result of percentage gastric empting after clinical improvement was 49.9%.
