(Results) There were 16 patients:12 with esophageal achalasia (EA), 3 with jackhammer esophagus (JE), and 1 with esophagogastric junction outlet obstruction (EGJOO). The median procedure time was 91 (65–196) min, and the median muscle layer dissection was 8.0 (5–21) cm. There were no severe adverse events. Following the procedure, symptoms were significantly improved (Eckardt score, median 5.5→1.5, p = 0.005; F scale, median 21.0→11.0, p = 0.004). Two months later, high-resolution manometry was performed on 13 patients. In 9 cases of EA and 1 case of EGJOO, the median integrated relaxation pressure was significantly decreased (29.6→10.1 mmHg, p < 0.005). In 3 cases of JE, the median distal contractile integral was improved (8831.4→849.2 mmHg/s/cm).
