Review for 10.1186/s12876-021-01629-4 (2021)

Reviewer’s report
Title: 
Case series of aortoenteric fistula: A rare cause of gastrointestinal bleeding
Version: 
1 
Date: 
28 Dec 2020
Reviewer's report:
The manuscript is well written and describes well-known features of aortoenteric
fistula. The number of cases of your series is important but smaller than in other
reports. I did not find any novelty in your manuscript and I don't think is of
interest for the readership of BMC journal.
