Reviewer’s report
Title: 
An extremely dangerous case of acute massive upper gastrointestinal
bleedingA case report
Version: 
1 
Date: 
10 Dec 2021
Reviewer's report:
This is a nicely written case report of a patient with massive bleeding caused by
fish bone piercing followed by mediastinal abscess that corroded the left
subclavian artery. The followings may be taken into consideration.
Was contrast enhanced CT performed for the patient? Was extravasation
observed? If not performed, what was the reason?
Regarding to laboratory data, other parameters (white blood cell, CRP, etc.)
inform readers of the patient's conditions.
Regarding to figure 3, it seems to be difficult especially for physicians to
understand anatomy. I suggest an additional schema about figure 3.
Did the patient received steroid therapy? Is it related to the mediastinal
abscess? Please discuss it with some references if possible.
