Title: 
Incarcerated gallbladder in inguinal hernia: A case report and literature review
Version: 
0 
Date:

Reviewer's report:
The authors submit this manuscript in "Case report" section. They present a rare case of incarcerated
gallbladder in inguinal hernia. Patient was diagnosed as inguinal hernia by physical examination and
abdominal sonography. Surgical finding revealed gallbladder in hernia sac. Patient recovered well after
treatment. After reviewing literature, only one case was reported before. 
Followings are my comments:
1. This manuscript is not well written in "Case presentation". This section needed to be shortened.
2. In this case report, all figures are intraoperative findings. Please add other diagnostic images before
operation (ex. sonography). 
3. In first paragraph of Discussion, authors address that elderly people maybe the characteristic in this rare
condition. Author cite Reference 4 "GB volvulus in elderly". How to explain volvulus background similar
to hernia. 
4. English editing is needed.
