Reviewer’s report
Title: 
Vedolizumab combined with surgical resection successfully treated
perforating Crohn’s disease with peritoneal space to rectal and vaginal fistulas: a
case report
Version: 
0 
Date: 
24 May 2021
Reviewer's report:
The 
authors report an interesting case in which a chrohn-induced rectovaginal
fistula healed using vedolizumab.
Some issues regarding the treatment have to be included in the manuscript.
Could the authors precise what was the surgical treatment of the fistula: only a
drainage or a specific procedure (epiplooplasty, suture)? 
What was the treatment protocol with vedolizumab (dose, duration, etc...)
In what delay after treatment did the fistula clinically healed?
Was there any crohn's disease location in the colon or in anal area?
