Achalasia -More Complexity to Pathophysiology?

RK Mittal et al. Gastroenterol 2020; 159: 864-72. Three-Dimensional Pressure Profile of the Lower Esophageal Sphincter and Crural Diaphragm in Patients with Achalasia Esophagus

This prospective study combined 3-dimensional high-resolution manometry (3D-HRM) with detailed analysis of computed tomography images to study the EGJ (esophagogastric junction) in patients with achalasia (n=12) and healthy controls (n=10). Key finding: Besides LES, the 3D pressure profile of the EGJ can indicate anatomic and functional abnormalities of the crural diaphragm muscle in patients with achalasia esophagus

“In this edition of Gastroenterology, researchers led by Ravi Mittal …demonstrated an asymmetric, extrinsic CD (crural diaphragm) component to EGJ pressure superimposed on the intrinsic LES.”
