GpCRC Pediatric Gastroparesis Registry 2: Characterization and Clinical Course of Symptoms and Gastric Emptying in Pediatric, Adolescent, and Young Adult Participants With Symptoms of Gastroparesis
The objective of the Pediatric Gastroparesis Registry 2 is to create a national prospective registry of children, adolescents, and young adults with gastroparesis and gastroparesis-like syndrome (symptoms of gastroparesis but normal gastric emptying).
• Provision of signed and dated informed consent form and assent, as age appropriate.
• Stated willingness to comply with all study procedures and availability for the duration of the study
• 8 to 25 years of age at the time of enrollment
• Symptoms of Gp of at least 12 weeks duration: constellation of some combination of:
⁃ nausea, vomiting, early satiety, postprandial fullness; symptoms sometimes may be accompanied by upper abdominal pain
• Have undergone a gastric emptying scintigraphic study of solids using 4-hour Egg Beaters protocol (or equivalent generic liquid egg white meal) within the last 12 months who fall into one of the two categories:
• Delayed gastric emptying-defined as an abnormal 2-hour (\>60% retention) and/or 4- hour (\>10% retention) result based on a 4-hour scintigraphic gastric emptying study
• Gastric emptying that is not delayed but who have symptoms of Gp (designated in this study as GLS) or have previously participated in the Pediatric Gastroparesis Registry (PGpR) study
• An etiology of either diabetic or idiopathic Gp or GLS
