Strict follow-up was performed.<\/jats:p><jats:p>\n          Results\u200245 patients were included, aged 45.5 years (interquartile range [IQR] 22\u200a\u2013\u200a69); 53\u200a% (24\/45) had type II achalasia. Median total time for thin-POEM was 54 minutes (IQR 37\u200a\u2013\u200a77) and median myotomy length was 13.5\u200acm (IQR 6\u200a\u2013\u200a20). Results pre-procedure and 3 months post were Eckardt score 10 vs. 1 (P\u200a&lt;\u200a0.001), integrated relaxation pressure (IRP) 25.3 vs. 8.5\u200ammHg (P\u200a&lt;\u200a0.001), and timed barium esophagram (TBE) 100\u200a% severely delayed vs. 86\u200a% normal (P\u200a&lt;\u200a0.001), respectively. Type III patients had the longest thin-POEM times (median 58 minutes [IQR 52\u200a\u2013\u200a77]). Reflux was confirmed at 3 months clinically in 17\u200a% of patients, endoscopically in 20\u200a%, and on pH monitoring in 53\u200a%.
