Title: 
Vaping-Associated Esophagitis: Case Report
Version: 
0 
Date: 
16 Jan 2021
Reviewer's report:
Authors reported a case report of vaping-associated esophagitis. This patient had
severe odynophagia after vaping tetrahydrocannabinol and nicotine. Endoscopic
pictures showed severe esophagitis (Los Angeles Grade C). I think vaping-
associated esophagitis is very rare disease. However, it is difficult to reveal that
this endoscopic finding is due to vaping the chemical substance. I believe that it
is necessary to survey increase of esophageal acid exposure in the way of PH
monitoring in the stomach and esophagus. Therefore, I consider that it is difficult
to accept their manuscript for BMC Gastroenterology.
