What this trial studies

The Pediatric Gastroparesis Registry 2 aims to establish a national prospective registry for children, adolescents, and young adults experiencing gastroparesis and gastroparesis-like syndrome. This observational study will collect data on the natural history and clinical course of participants, focusing on symptoms such as nausea, vomiting, and abdominal pain. By capturing demographic, clinical, physiological, and patient-reported outcome data, the registry seeks to enhance understanding of these gastrointestinal disorders and their impact on young patients.

Who should consider this trial

Good fit: Ideal candidates for this study are children and young adults aged 8 to 25 who have experienced symptoms of gastroparesis for at least 12 weeks.

Not a fit: Patients who do not exhibit symptoms of gastroparesis or who are outside the age range of 8 to 25 years may not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could lead to improved diagnosis and management strategies for pediatric patients with gastroparesis.

How similar studies have performed: Other studies have successfully utilized registry approaches to better understand gastrointestinal disorders, indicating potential for this study's success.

* 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

Exclusion Criteria:

* Inability to comply with or complete the scintigraphic gastric emptying test (including allergy to eggs)
* Pregnancy

* Presence of any other condition that could case delayed gastric emptying
* Gastrointestinal construction confirmed by upper endoscopy (EGD), upper gastrointestinal series (UGI), or abdominal CT
* Primary neurological conditions that can cause nausea and vomiting such as increased intracranial pressure, space occupying or inflammatory/infectious legions
* Acute or chronic renal failure (abnormal creatinine for age) and /or on hemodialysis or peritoneal dialysis
* Acute liver failure
* Advanced liver disease (features of portal hypertension)
* Clinically significant congenital heart disease (i.e., vaginal injury during cardiac repair)
* History of esophageal, gastric or bowel surgery.
* Metabolic disease including mitochondrial disease and inborn errors of metabolism
* Chronic lung disease (including cystic fibrosis)
* A serious chronic medical condition (e.g., inflammatory bowel disease)
* Use of medications that can affect motility during the gastric emptying study
* Any other condition, which in the option of the investigator, could explain the symptoms or could interfere with study requirements.
