Reviewer’s report
Title:

duodenum after leading to duodenal perforation: a case report
Version: 
1 
Date: 
05 Oct 2020
Reviewer's report:
The case is interesting and rare. But the paper needs major revision 
1. The initial patient evaluation is not discussed well including some
investigations like X ray, WBC count and other lab works 
2. The patient management is not discussed well (Conservative treatment, The
detailed surgical procedures). The detailed things that need to be included are
attached in the comment box 
3. The procedures has to be described well. The detailed things that need to be
included are attached in the comment box
4. The post operative report is incomplete. The detailed things that need to be
included are attached in the comment box
5. The discussion has to be written again. it is just the description of the
procedures and doesn't compare the study with literatures 
6. The language needs revision 
NB. You can find my detailed comments on each area on a comment box of the
attached original document after highlighting the areas that need modification.
