Gastric Emptying Scintigraphy Before Gastric per Oral Endoscopic Myotomy: Imaging May Inform Treatment

Robert M Spandorfer et al. Gastrointest Endosc Clin N Am. 2019 Jan.

Abstract

Gastric emptying scintigraphy (GES) helps to diagnose gastroparesis and is typically only used for whole stomach retention patterns. However, it may provide significantly more information when looking specifically at proximal and distal retention patterns. This article reviews global GES changes following gastric per oral endoscopic myotomy; how global, proximal, and distal GES measurements correlate to gastroparesis symptoms; and how proximal and distal GES may serve as proxies for the various mechanisms involved in gastroparesis. The authors' data on how GES may be used to select which patients will have success from G-POEM is also reviewed.

Keywords: Distal; G-POEM; GES; Gastroparesis; POP; Proximal; Pyloromyotomy; Scintigraphy.
