Reviewer's report:  
This is an interesting case of self dilation. Below are some of my comments.  
 
1. Title: Title can be modified as "Recurrent esophageal stricture from previous caustic ingestion, 
treated with 40 years of self dilation: case report and revi ew of literature"  
2. The background part can be labelled as introduction and can be shortened.  
3. Throughout the manuscript, there are a lot of english spelling and grammatical errors. Would 
request the authors to improve english and then re -submit the art icle. I lost interest in reading 
due to so many errors.  
4. The discussion can be written in a better flow and in more than 1 paragraph. 1 para for 
quantifying the problem. 1 paragraph for current endoscopic practices and potential other 
treatments like ste roid injections/mitomycin and surgical approach. Then defining a resistant 
stricture, % of strictures that are resistant and then forming a base to say that self dilation in 
feasible etc. In this day, it is difficult to convince any GI doctors to go this r oute. So, 
discussion should focus on strong data in favor of safety and outcomes of self dilation to make 
a good case for it. Again, this would be applicable in very selective group of patients who 
have endoscopically resistant benign strictures, and/or po or candidates for anesthesia or cost 
issues.
