Esophageal High-Resolution Manometry Can Unravel the Mechanisms by Which Different Bariatric Techniques Produce Different Reflux Exposures

Bariatric surgery is increasingly performed. Since there are numerous surgical techniques, the effects of these on the esophageal function are still poorly understood. We aimed at assessing the effect of different techniques on esophagogastric junction (EGJ), esophageal peristalsis and reflux exposure using high-resolution manometry (HRM), and impedance-pH monitoring (MII-pH). All obese patients underwent symptomatic questionnaires, endoscopy,...
