Version: 
0 
Date:

Reviewer's report:
Nice and informative case report summarizing literature and treatment options.
Are endoscopic images available to add to the manuscript next to the barium
swallowing x-rays? Could the auhtors add a little more information about
treatment outcomes; surgery vs endoscopic for example? What is the recurrence
rate and the incidence of complications, et cetera?
