In this study,1 30 patients with achalasia underwent evaluation with high-resolution manometry and esophageal pressure topography before and after myotomy. Myotomies were laparoscopic, open, or peroral endoscopic procedures in 24, 1, and 5 patients, respectively. Before treatment, patients were classified into 3 groups according to the Chicago classification. Type 1 elicited no peristalsis or pressurization (8 [27%]), type 2 elicited panesophageal pressurization only (17 [57%]), and type 3 showed premature contractions (5 [17%]). Only type 3 patients demonstrated peristalsis before treatment; however, after myotomy, peristaltic activity was noted in 63%, 47%, and 80% of types 1, 2, and 3 patients, respectively.
