Title: 
Dorsal approach with Glissonian approach for laparoscopic right anatomic
liver resections
Version: 
1 
Date: 
17 Mar 2020
Reviewer's report:
The authors described the procedure of laparoscopic right hemihepatectomy,
right posterior sectionectomy, and S7 using dorsal approach.
In laparoscopic hepatectomy, approach from the dorsal side has some advantages
in laparoscopic surgery. 
However, the author should address some points below.
1. During right hemihepatectomy, the procedure of identifying the root of MHV
was performed in a narrow limited view. The procedure seems to become easy
after full mobilization of the right lobe. After the exposure of the root of the
MHV, is it difficult to transect the liver parenchyma along the MHV from the
root side to the periphery from the dorsal side?
2. During right posterior sectionectomy, is it also difficult to transect the liver
parenchyma along the RHV from the root side to the periphery from the dorsal
side?
3. The comparison among LRH, LRPH, and LS7 is not important and necessary. 
4.Estimated blood loss was not so low even in laparoscopic hemihepatectomy.
