Title: A Rare Cause of Dysphagia Due to Esophageal Intramural Pseudodiverticulosis: A Case  
Report and Review of Li terature  
 
Version: 1 Date: 16 Oct 2019  
 
Reviewer: Saikiran Raghavapuram  
 
Reviewer's report:  
 
Authors have described a rare case of esophageal intramural pseudodiverticulosis. Though its is 
rare, it is well reported in the literature.  
 
 
I have following comments/suggestions to the authors:  
 
 
1) What prompted authors to obtain barium esophagogram after the initial EGD showing severe 
esophageal stenosis? Are authors concerned about missing some other diagnosis which would be 
helped by a bariu m esophagogram?  
 
 
2) There are certain grammatical mistakes in the case report. a) On page 5, comma after "reports 
of critically ill patients" can be followed by period (full stop) and the following sentence can be 
written as "EIP was the proposed underlyin g cause of increased intraluminal pressure leading to 
esophageal perforation and pneumomediastinum is those two cases. b) On page 6, in the first 
paragraph, a period can be used in place of comma after "interconnecting and bridging to one 
another" and the following sentence can be started with "Although".  
 
 
3) Was there a follow up longer than 3 weeks on this patient to see if the dysphagia has recurred 
post dilatation?  
 
 
4) Is there any data about the chance and risks of perforation of such pseudodiverticulae post 
dilatation? Is there any data regarding bacterial infection of such pseudodiverticulae? Is there any 
data regarding the incidence of esophageal cancer in such pa tients and how often endoscopy is 
recommended for it's detection?
