Title: Comparison of operative outcomes between monopolar and bipolar coagulation in
hepatectomy: a propensity score-matched analysis in a single center
Version: 1 Date: 25 Jan 2022
Reviewer's report:
Muraki et al. reported on the operative outcomes after monopolar or bipolar coagulation during
hepatectomy. All in all, the design of the manuscript is well-thought-out and written. However,
I have several concerns I like the authors to address:
1. Arguably, the choice of the hemostatic coagulation and cutting devices may have a direct
impact on the postoperative course - much like the choice between monopolar or bipolar
coagulation. Yet the authors fail to include this crucial information in the manuscript. Please
add these data to the manuscript. If the difference between monopolar and bipolar groups is
significant, hemostatic coagulation devices should be included as a parameter of propensity
score matching.
2.  Ascites is not defined in the methods section. Please revise.
