The antrum grinds and sieves solids, and pumps chyme into the duodenum against pyloric resistance. The timing of antral contractions is related to the frequency of an electrical slow wave ...

But the antrum also seems to ex ert a balancing effect, and Dr. Bartlett’s M.G.H. team has had good results from a vagotomy combined with removal of about half the stomach but leaving a small ...

This procedure has been well described by McKittrick 9 and endorsed by Allen 10 and others. 11 In essence, the stomach is deliberately divided through the antrum well proximal to the pylorus (Fig ...

FIGURE 1. (A) Baseline 18 F-FDG PET/CT showed gastric, nodal, and osseous metastases. Arrow depicts 18 F-FDG–avid lesion involving gastric antrum and pylorus in baseline PET scan, corresponding with ...

Obesity is defined as a body mass index (BMI) of 30 kg/m 2 or over. The degree of obesity is classified as: obesity class 1 (BMI 30 kg/m 2 to 34.9 kg/m 2). obesity class 2 (BMI 35 kg/m 2 to 39.9 kg/m ...

A 1.5-cm-long gastrotomy at the antrum allowed direct visualisation of the inflamed but intact mucosa of the pyloric channel. We noticed a mass effect by the anterior pyloric mass with obstruction of ...

There was abnormal circumferential wall thickening (≤13 mm) in the stomach, particularly at the antrum, incisura, and pyloric canal . The antrum was decompressed or nonexpansile, and the rest of ...
