Reviewer's report:
Thank you for the opportunity to review this very unusual case report. In my 20-year tenure of inguinal
hernia repair. 
I have never encountered such situation and had never read about this until now. 
In general, the entire paper needs to be reviewed by a native speaker of the English language to correct all
the language use errors that exist throughout the manuscript. 
The background is exceedingly short and
some information as to why is it is important to document such an usual finding would be in order.
Treating hernias is no longer a challenge. 
It is a common operation, but highly routine in most hospitals
around the world. 
The case presentation is also somewhat vague. 
It is assumed that the hernia was not incarcerated
previously when the elective operation was being planned, but this is not clear. 
Why was imaging needed for what appeared to be an incarcerated groin hernia? If some imaging would
have helped, why not a CT scan? 
What is a passage disorder? 
What is the value of obtaining and reporting
C-reactive protein for an inguinal hernia? Same for LFTs. 
Why did you leave a drain? 
How long was the follow up to determine that there was no recurrence? 
Incarcerated inguinal hernias are not common, reducible hernias and the repair is, but not incarcerated
hernias themselves. 
In the sentence, "the mean age of the publications is high". 
What publications are the authors refereeing to.
A table here would be nice with appropriate references. 
Also, all values require standard deviation or
SEM. 
Female is not an adjective, but a noun. 
The methodology needs to include a couple of sentences on how the literature search was performed. 
As
the authors have cited the manuscript:
Gallbladder protrusion through the groin region—a very unusual femoral hernia. By Kreutz Rodrigues et
al. 
They should use some of the formatting for their paper.
