The aims of the present study was to define the clinical features, response to therapy, and outcome of pediatric gastroparesis.


Retrospective review of 230 children with gastroparesis. Demographics, gastric emptying times, symptoms, response to medications, and outcome were determined for each of 3 groups (infants, children, and adolescents).


Mean age was 9 years, with boys predominating among infants and girls among adolescents. Postviral gastroparesis occurred in 18% and mitochondrial dysfunction (MD) in 8%. Symptoms varied with age, with children experiencing more vomiting and adolescents reporting more nausea and abdominal pain. The addition of promotility drugs was an effective therapy. Overall rates of symptom resolution were 22% at 6 months, 53% at 18 months, and 61% at 36 months, with median time to resolution of 14 months. Factors associated with symptom resolution included younger age, male sex, postviral gastroparesis, shorter duration of symptoms, response to addition of promotility therapy, and absence of MD. In multivariate analysis, longer duration of symptoms and MD both predicted lower rates of resolution, whereas younger age and response to addition of promotility therapy predicted a higher rate.


Pediatric gastroparesis is a complex condition with variable symptomatology and outcome depending on multiple parameters. Understanding the clinical features and response to therapy will improve our diagnosis and treatment of this disorder.
