Abstract: Gastroesophageal reflux disease (GERD) is the most common disease of the upper gastrointestinal tract in the Western world. GERD pathophysiology is multifactorial. Different mechanisms may contribute to GERD including an increase in the transdiaphragmatic pressure gradient (TPG). The pathophysiology of GERD linked to TPG is not entirely understood. This review shows that TPG is an important contributor to GERD even when an intact esophagogastric barrier is present in the setting of obesity and pulmonary diseas… Show more

“…8 In certain circumstances, GERD may occur in the setting of a normal valvular mechanism due to an altered transdiaphragmatic pressure gradient. 9 Abdominal pressure may be abnormally increased surpassing the retention pressure of the esophagogastric valve in obese patients. 10 On the other side, thoracic pressure may be decreased in patients with restrictive pulmonary diseases 11 : this may be the case in patients with IPF.

“…In the journal Arquivos de Gastroenterologia, two articles were published simultaneously, emanating from one institution and devoted to high resolution manometry (HRM) of the esophagus and the lower esophageal sphincter (1,2) . The first study aims to determinate the normative data for a new 24 channel water-perfused HRM (1) .…”
