Reviewer’s report
Title: 
Surgical Outcomes of LigaSure Hemorrhoidectomy in the Elderly
Population: A retrospective cohort study
Version: 
1 
Date: 
19 Jul 2021
Reviewer's report:
This is a study reagarding a very large amount of patients operated on in a single
institution. It's not common that one hospital performs fifty hemorrhoidectomies
in a month and it's possible that many of these patients have been submitted to
an excisional treatment instead of receiving 
a smoother operation. The results
you present are very good both in young and old patients and you must be
congratulated for this but really I could not expect a difference in the outcome of
the two compared groups being the Ferguson operation a very well 
standardized
method for all patients needing an excisional hemorrhoidectomy. I suggest that
you ask for help because the english language must be improved.
