TL;DR: This consensus statement from the members of the American Neurogastroenterology and Motility Society and the Society of Nuclear Medicine recommends a standardized method for measuring gastric emptying by scintigraphy, and recommends a low-fat, egg-white meal with imaging at 0, 1, 2, and 4 h after meal ingestion.

Journal ArticleDOI
Demography, clinical characteristics, psychological and abuse profiles, treatment, and long-term follow-up of patients with gastroparesis
TL;DR: Agood response to pharmacological agents can be expected in the viral and dyspeptic subgroups ofidiopathic gastroparesis, Parkinson's disease, and the majority of diabetics, whereas a poorer outcome to prokinetics canbe expected in postgastrectomy patients, those withconnective tissue disease, a subgroup of diabetes, andthe subset of idiopaths dominated by abdominal pain.
