In the Pediatric Gastroparesis Registry (PGpR), we will collect detailed epidemiological, clinical, psychological, and patient outcome data with the goal of classifying patients with gastroparesis and gastroparesis-like syndromes into pathophysiologically defined phenotypes. The Primary Objective is to create a national prospective registry of children and adolescents with gastroparesis and gastroparesis-like syndrome (symptoms of gastroparesis but normal gastric emptying) to include: Demographic, clinical, psychological, nutritional characteristics, physiological measures, and serial assessments of symptoms over 3 years while receiving clinical care; Establish a Biorepository of plasma, serum, peripheral blood mononuclear cells (PBMC), GI mucosal biopsies (in those undergoing upper GI endoscopy), urine and stool collected from the children and adolescents in this registry which will allow for future analyses such as cytokines, bacterial DNA and microbiome to investigate the etiology and pathogenesis of gastroparesis in children. Secondary Objectives: To determine what factors, if any, play a role in the outcomes of children who do not improve within two years of diagnosis To assess the spectrum of symptom severity of the cardinal gastroparesis symptoms: nausea, vomiting, early satiety, postprandial fullness (and upper abdominal pain, if present) in children with gastroparesis To assess several areas of gastric motility in pediatric patients with symptoms of gastroparesis (e.g., intragastric meal distribution, global gastric emptying) To capture the clinical symptomatic course (outcome) of pediatric patients followed in the registry To determine whether gastroparesis symptoms are correlated with gastric emptying in a pediatric population To characterize abdominal pain in patients with gastroparesis and gastroparesis-like syndrome by using questionnaires, water load satiety testing and quantitative sensory testing (QST) Determine the prevalence of hypermobility spectrum disorders in pediatric patients with gastroparesis To determine if the volume of water consumed during the water load satiety test is an indirect measure of gastric accommodation To determine if the water load satiety test is associated with an increased severity of gastroparesis symptoms (fullness, bloating, abdominal pain, etc). To compare the intragastric meal distribution during scintigraphy to symptoms of early satiety, postprandial fullness in patients with symptoms of gastroparesis Define immune cell profiles, cytokine induction and epigenetic changes in diabetic and idiopathic gastroparesis
