Reviewer ’s report  
 
Title: Two cases of agenesis of the dorsal pancreas and a review of the literature  
 
Version: 0 Date: 14 Feb 2020  
 
Reviewer: Yusuke Ishida  
 
Reviewer's report:  
 
Although agenesis of the dorsal pancreas is unusual congenital abnormality, it is not extremely 
rare. Additionally, only CT scan was conducted in this article, it is difficult to exclude the 
possibility of pancreatic hypoplasia or ot her disorders; therefore, I'm afraid I can't fine any new 
discoveries with this case report.  
 
Authors should clearly describe the novelty or difference between the present cases and the cases 
in the previous literature.  
The lack of dorsal pancreas should be more clearly demonstrated , for example, by multi -planar 
reconstruction CT image, because the cases in this report were diagnosed only by CT scan.
