Title: Association between gastrointestinal lesions in individuals undergoing gastroscopy and
colonoscopy simultaneously: a retrospective, observational study
Version: 0 Date: 11 Sep 2024
Reviewer's report:
The authors analyzed approximately 18,000 patients who underwent upper and lower GI
endoscopy at the same time or at similar times. The results showed that CAG was the most
common in upper GI endoscopy and CPs in lower GI endoscopy, and these were more common
in older patients and in men. CAG and CPs showed an association regardless of age or gender.
I think this is a well-analyzed and well-written paper that covers a large number of patients.
As this was a retrospective study, many variables could have had an influence, but I think it is
compensated by the large number of patients, and I think the prevalence of each gastrointestinal
disease is similar to what is already known. Therefore, I think that this paper can serve as an
evidence for performing upper and lower GI endoscopy simultaneously, which is commonly
performed in clinical practice.
Minor comments
1. It would be nice to have a specific mention of the principles for patients who underwent upper
and lower GI endoscopy on the same day in the "Endoscopic procedure" of Methods (e.g. which
endoscopy was performed first, and if sedation endoscopy was performed, what drugs were used
and how much was used).
2. In Table 3, instead of distinguishing between Yes/No, why not just express it as n (%) next
to the disease?
