Reviewer ’s report

bleeding: a case report and literature review  
 
Version: 2 Date: 19 Jun 2018  
 
Reviewer: Chen Shuan Chung  
 
Reviewer's report:  
 
Some revisions should be made before consideration for publication.  
1. "Three cavity two capsules" were placed to hemostasis by compression and tube feeding 
hemostatic medicine. => Please explain what is "three cavity two capsules" more clearly.  
 
2. Page 4, line 58: Please provide normal range of IgG and IgG4.  
 
3. In figure 1, the CT images could not well delineate the lesion mentioned in the figure legend. 
I could not see LAPs in figure 1B, and the lesion indicated by the arrow in figure 1C should 
be the artery rather than a hypervascular lesion. Please provide CT images with better 
quality.  
 
4. In figure 2, the endoscopic picture of duodenal ulcer seemed to be not interesting. Do you 
have image enhanced endoscopic picture, such as NBI with magnifica tion, for the 
interpretation of duodenal ulcer with unusual etiology ? Is there any endoscopic hint 
indicating IgG4 related disease?  
Are the methods appropriate and well described?  
If not, please specify what is required in your comments to the authors.
