Simple and non-invasive assessment of the accommodation reflex of the proximal stomach.

Background: Impaired gastric accommodation of the proximal stomach is one of the major pathophysiological mechanisms in functional dyspepsia (FD). However, no useful method exists for the clinical evaluation of this phenomenon.

Aim: The aim of the present study was to establish a simple and non-invasive method for evaluating the accommodation reflex of the proximal stomach.

Giant gastric folds: differential diagnosis at US.

Purpose: To evaluate ultrasonographic (US) features in the differential diagnosis of giant gastric folds.

Materials And Methods: One hundred sixty-five patients with giant gastric folds at transabdominal US examination (five with Ménétrier disease, 24 with anisakiasis, 61 with acute gastric mucosal lesion [AGML], 13 with gastric lymphoma, and 62 with scirrhous carcinoma) were examined. With 3-6-MHz curved and 5-11-MHz linear-array transducers, the authors evaluated gastric wall thickness, wall stratification, main thickened layer, echogenicity, and compressibility of the lesion in each case.
