Intraoperative Study on the Relationship Between the Lower Esophageal Sphincter Pressure and the Muscular Components of the Gastro-Esophageal Junction in Achalasic Patients

Abstract

In achalasic patients, 45% of the LES resting tone is maintained by the gastric side anatomical component of the GE junction. The range of variability of the gastric component of the LES is wide. This information should be taken into account when performing extramucosal myotomy as therapy for esophageal achalasia.
