Reviewer's report:  
 
Clinical  practice  of  basin -shaped hepaticojejunostomy  following  hilar  resection  of stage IV 
hilar cholangiocarcinoma  
I read with great interest the article entitled Clinical  practice  of  basin -shaped 
hepaticojejunostomy  following  hilar  resecti on  of stage IV hilar cholangiocarcinoma  
The aim  of  this  study was to determine, in patients suffering from stage IV hilar 
holangiocarcinoma , safety and effects of  basin -shaped  biliary -enteric  anastomosis  after  
segment  IV/extended IV   
 
I have several comments  
Major comments:  
1. Are all patients really type IV. Indeed, if the described technique, is to pediculize the 
biliary ducs, after section, on 5 mm and knowing that the section has been carried out 
already at 5 mm of tumor, because all pati ents are R0, there should be few patients with 4 
bile stumps and in addition anastomoses are carried out on 1 to 2 mm stumps. therefore, 
there are some examples of MRI in the manuscript.  
 
2. How was defined the R0 character of the resection: whether or not perineural invasion 
was integrated into the margin, or was it only with reference to that of the biliary margin ? 
 
3. Can the authors describe the management they have had of the arterial vascularization of 
the remnant bile ducts. Indeed, by definition, a b ile ducts cross section at this location 
leads to arterial devascularization. this point is probably the most important moment of 
this study.  
 
4. What was the mean foolow -up 
 
5. We need a survival curves (DFS and OS)  
Minor comments:  
6. Segment IV/extended IV , does it mean to the segment I ? => autors need to use the 
Brisbane classification for hepatectomy and by the way clavien classification for 
complication.  
 
7. Can the authors describe more precisely the type of recurrence.  
 
8. How many patients had different surgical management during the same period for the 
same type of lesion.  
Are the methods appropriate and well described?

No
