When the above article was first published online, the data in the results of the abstract was not correct and should be rewrote as (Data could be referenced in Table II–IV):
Peroral endoscopic myotomy (POEM) procedures were completed in five stomach–esophagus models, with perforations in the initial three and success in the last two. A total of 36 achalasia patients (22 males, 14 females) with achalasia successfully underwent POEM. The mean operation time was 72.8 min (range, 45–180 min). There were major complications in three patients: one case of severe bleeding and two cases of pneumothorax, which were treated successfully. During the follow-up period, the median Eckardt score decreased dramatically from 8 to 1 (p = 0.000). The lower basal esophageal sphincter pressure decreased markedly (36.1 ± 14.3 vs. 11.9 ± 4.6 mmHg, p = 0.000), as well as the 4-s integrated relaxation pressure (12.9 ± 13.0 vs. 6.6 ± 2.9 mmHg, p = 0.000).
In the results of the manuscript (Page 3, In vivo clinical results), the number of mean procedure time should be 72.8 ± 26.2 min instead of 8 ± 26.2 min.
YUTANG REN & XIAOWEI TANG apologize for those errors.
