Reviewer's report: 
The authors resected the esophagus leiomyoma which caused pseudoachalasia by tunnel 
endoscopy. I think it to be a very interesting case  report. I ask some questions. 
 
1. The authors stated that an achalasia symptom was  caused for esophagus leiomyoma.  I think 
that esophagus leiomyoma meets for common disease w ell. However, its most are 
asymptomatic. Why is it that this case presented an  achalasia symptom? 
2. The authors say that resection was successful by  tunnel endoscopy.  I want you to prove that 
it is complete resection pathologically.
