by choledochoscopic needle -knife electrotomy: a case report.  
 
Version: 1 Date: 08 Feb 2018  
 
Reviewer: Keita Kai  
 
Reviewer's report:  
This is a case report of hepatic simple cyst causing obstructive jaundice. First of all, the quality 
of English is not sufficient for publication. Because of inappropriate usage of English, it is 
difficult for readers to understand situation of the case. W hat is "capsular goiter" or "common 
duct goiter"? I cannot understand it. The discussion section is documented as "conclusion". It is 
also inappropriate. The content of discussion section is also insufficient. The authors should 
review more detail of previ ous reports and should clearly explain what is the difference of 
previous series and what is the valuable features or clinical implications of present case.  
Are the methods appropriate and well described?  
If not, please specify what is required in your comments to the authors.  
No 
Does the work include the necessary controls?  
If not, please specify which controls are required in your comments to the authors.  
No 
Are the conclusions drawn adequately supported by the data shown?  
If not, please explain in your comments to the authors.  
No 
Are you able to assess any statistics in the manuscript or would you recommend an 
additional statistical review?  
If an addition al statistical review is recommended, please specify what aspects require further  
assessment in your comments to the editors.  
Not relevant to this manuscript
