Reviewer: Gregorios Paspatis
Reviewer's report:
General comments
This is a well designed study. The data were collected prospectively and they
were analyzed retrospectively (hisrorical cohort). Indded the existed data in the
literature regarding peforations in colonoscopy are adequate.However data
regarding the risk factors associated to colonic prforations are valuable.The
paper is well written.
Specific comments
1.Colonoscopic perforation occur more often in women. The authors should
mention this point in the Discussion
2. It would be interesting to present the number of snare polypectomies and
endoscopic mucosal resection
Level of interest: An article whose findings are important to those with closely
related research interests
Quality of written English: Acceptable
Statistical review: Yes, but I do not feel adequately qualified to assess the
statistics.
