Electrogastrography in Adult Gastroparesis: A Systematic Review and Meta-Analysis.

Background: Gastroparesis is a delay in gastric emptying without mechanical obstruction, lacking a clear pathophysiological mechanism, but with multiple histological abnormalities including loss of interstitial cells of Cajal, which may alter slow waves. We can assess slow waves with electrogastrography.

Objectives: To determine the prevalence and range of abnormalities in gastric slow waves in adults with gastroparesis using electrogastrography.
