Title:The association between cecal insertion time and colorectal neoplasm
detection
Version: 1Date:3 April 2013
Reviewer: Aijaz AS Sofi
Reviewer's report:
Minor revision-
Sung et. al have retrospectively examined the relation between adenoma
detection rate and cecal insertion time. The findings in this paper are interesting.
This paper highlights the importance of more careful examination of colon in
patients who have longer cecal insertion time (CIT), which is an indirect measure
of difficult colonoscopy.
Comments- Although patient or colonic related factors, as mentioned by the
authors in the conclusion section, could be contributing to higher adenoma miss
rate in patients with longer CIT. However, the higher adenoma miss rate in the
patients with difficult colonoscopy (and thus longer CIT) could also be related to
endoscopist exhaustion from difficult colonoscopy and the stress from scheduling
and therefore endoscopist could miss smaller adenomas in relatively difficult to
visualize areas in colon- this might also contribute to higher miss rate of small
adenomas only (<5 mm in this study).
Level of interest: An article of outstanding merit and interest in its field
Quality of written English: Acceptable
Statistical review: Yes, and I have assessed the statistics in my report.
