Gastroparetic patients were enrolled at 8 centers into the NIH Gastroparesis Registry from September 2012 to August 2015. Enrolled patients met specific entry criteria being 18 years or older with symptoms of at least 12 weeks duration, delayed gastric emptying scintigraphy (GES) within 6 months of enrollment, and no structural abnormality as seen by upper endoscopy within one year of enrollment.
This report focuses on patients with either idiopathic or diabetic gastroparesis. The diabetic patients could have either Type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) as defined by the physician and/or patient. The diagnosis of patients with the idiopathic etiology was based on no previous gastric surgery, no diabetes history (before or after the onset of gastroparesis at enrollment), a normal hemoglobin A1C, and no other known etiologies.
All studies were approved by the Institutional Review Board at each Clinical Center and at the Data Coordinating Center.
