Practice guidelines

AGA best practices review (2021)

“GES does improve refractory nausea and vomiting in some patients with gastroparesis and may improve glycemic control, nutritional status, and quality of life, while reducing hospitalizations and medication use.”1

ACG practice guidelines (2013)

“Conditional recommendation, moderate level of evidence, may be considered for compassionate use in patients with refractory symptoms, particularly nausea and vomiting.”2
