Abnormal gastric electrophysiology following laparoscopic sleeve gastrectomy and associations with symptoms and quality of life.

ABSTRACT:

Background

Sleeve gastrectomy is an effective bariatric procedure but may lead to persistent symptoms without obvious mechanical cause. The normal gastric pacemaker region, which lies on the greater curvature of the corpus, is resected in sleeve gastrectomy, but the electrophysiological consequences are not adequately defined. This study assessed these impacts and associations with symptoms and quality of life (QoL) using non-invasive gastric mapping.

Methods

Patients with previous sleeve gastrectomy underwent body surface gastric mapping (Gastric Alimetry), comprising 30-minute fasting baseline and 4-hour post-prandial recordings. Analysis encompassed principal gastric frequency (PGF), body mass index-adjusted amplitude, and the Gastric Alimetry Rhythm Index (GA-RI), with c
