Reviewer's report:
Queries for the Authors
1) Can you give more in-depth information regarding the symptoms and signs of
constipation in the child? Particularly difficulty passing bowel movements and
presence or absence of rectal prolapse.
2) A better description of the findings at colonoscopy and of the pathology are
needed in the text portion of the manuscript.
3) Are there any follow-up images after complete eradication of the polyps?
4) What is the duration of follow-up since eradication of the polyps? Some of
these conditions can recur following treatment.
5) The table is not needed, that information can be given in the text of the case
report.
6) Figure 1 can be limited to a single image.
7) Figure 2 can be limited to 2 images - either "A" or "C" can be eliminated.
8) Significant editing of grammar and syntax is needed.
9) Your conclusion states that SRU may "transform" into cap polyposis.
However, a mechanism for both solitary rectal ulcer syndrome and cap polyposis
is rectal prolapse. I think that conclusion is too strong and cannot be proved.
10)
