Title: The impact of endoscopist performance and patient factors on distal adenoma detection
and colorectal cancer incidence.
Version: 1 Date: 17 Oct 2023
Reviewer's report:
This is a high-quality study, but there are several problems:
1. Should positive results from repeated FS be included? Multiple FS examinations could reduce
the miss rate of adenomas, which may be the reason for the high ADR of distal colon with poor
bowel preparation compared with excellent.
2. The amount of time it takes to deal with the polyp during insertion or withdrawal may need to
be excluded. Negative FS examinations have no polyps to operate, so the insertion or withdrawal
time will be shorter, which may be the reason for the high detection rate of distal colorectal
adenoma of longer insertion or withdrawal time.
3. The end point of FS examination is not fixed, and the study concluded that the further the
segment is inserted, the detection of adenoma will also improve. However, the extension of the
insertion distance means that the insertion time and the withdrawal time will also be extended,
which may be another factor affecting the high detection rate of distal colorectal adenoma of
longer insertion or withdrawal time.
