Reviewer's report:  
 
 This manuscript has become more scientific and easily understa ndable after revision. 
However, this manuscript still has some problems to be corrected. My suggestion is below:  
 
1.There are mixed use of Santorini's duct and SD in this manuscr ipt. The authors should use the 
word "Santorini duct" at first appearance only and SD thereafter.  
2.In page 4, the word "IPNA" is incorrect.
