Type II achalasia. What can be hidden behind panesophageal pressurization?

Abstract

The aim was to investigate features of manometric pattern of type II achalasia.Materials and methods: High-resolution esophgeal manometry (HRM) was performed in 250 patients with achalasia. In 154 cases patients underwent peroral esophageal myotomy (POEM).Results: We found that poor results after POEM showed patients with high preoperative esophageal pressurization (>80 mm Hg). The poorest result after POEM we observed in patient with short additional increase of panesophageal pressure (up to 95 mm Hg) withing the contour of panesophageal pressurization.
