An inverse relationship was observed in the distal and proximal antrum for density (proximal vs distal: 9.8% 4.0% vs 7.6% 4.6%) and thickness (proximal vs distal: 15 3 mm vs 24 10 mm).

Thus, for example, is a biopsy sample taken from the greater curvature section of the gastric body identical to the anterior or posterior wall or the lesser curvature
of the same region of the stomach?

he procedure consists of the following 3 steps: (1) pylorus-sparing antral myotomy via a submucosal tunneling technique to weaken the antral pump and impede emptying, (2) a running suture at the level of the incisura to separate the antrum from the gastric body and to minimize tension on the myotomy access site closure, and (3) a standard ESG in the gastric body to reduce mixing and limit accommodation (Figure 2).
