Reviewer’s report
Title: 
Migration of fish bones into abdominal para-aortic tissue from the
duodenum after leading to duodenal perforation: a case report
Version: 
1 
Date: 
18 Sep 2020
Reviewer's report:
There is no novelty: multiple similar reports are available for foreign bodies
including fish bone in duodenum 
Perhaps the only interesting thing 
is the surgical management 
Many details about the case mentioned in discussion should be in Case
Presentation 
Difficult to fathom how gastroscope could not identify the perforation and
colonoscope was needed
