PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: 1. There are issues with the language and spelling
2. In introduction, the statement about "Laparoscopic hepatectomy has become a
common therapy for treating liver tumors in recent years" is not 100% true.
Please soften this sentence. 
3. Laparoscopic liver surgery provides significant benefits to eligible patients
regarding recovery. 
I would refrain from making strong statements, such as
lower blood loss, and emphasize more the minimally invasive nature and faster
recovery throughout the manuscript, including the Introduction.
4. The tense changes from past to present tense frequently in the text. They
authors need to be consistent.
5. The functional remnant volume above 40% is usually accepted adequate in a
patient with cirrhosis. However, the authors decided to do PVE with a remnant
of 42%. Please explain and discuss why.
6. Also, after PVE generally, 4-6 weeks are waited for the liver to hypertrophy.
The authors waited 9 days. Please discuss.
7. The patient was discharged home on day 7, which is not much different from
open resection. Please discuss. 
8. It would be tough to make generalizations about laparoscopic liver resection
vs ALLPS or open surgery. 
9. I do not think the graph showing the changes in labs is necessary. 
Overall, 
the authors have performed a unique procedure. I suggest they focus
more on being able to do this procedure laparoscopically and not try to cover too
many topics and make too many generalization about the disease process. They
should focus on technical uniqueness, maybe share surgical tips and remove
unnecessary digressions and elaborations in the manuscript. 
In line with this, I
would like to see more underscoring of the surgical technique, maybe even
intraop videos. 
Currently, they are trying to cover too many topics with one case
report and since the language is inadequate in quality, the longer the manuscript
is, the more difficult is to keep the grammar and language standards.
REQUESTED REVISIONS:
