Reviewer’ s report
Title: Type IV choledochal cyst with polycystic kidney disease:A case report
Version: 0Date: 17 Feb 2020
Reviewer: Mariusz Niemczyk
Reviewer's report:
1. In fact, coexistence of type 4a choledochal cysts with ADPKD is very rare; however, it is not
true that such coexistence has never been reported (see https://www.ijmedicine.com/index.php/ijam/article/view/401/358). This issue should be clarified in the manuscript and this paper shouldbe cited.
2. The diagnosis of ADPKD is poorly justified: what about a family history for ADPKD? what
were the diameters of the kidneys? I expect inclusion of these information into the manuscript.
3. To improve the educational value of the paper, the Todani's classification of choledochal cysts
should be included into this paper.
