PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: WHAT IS YOUR OVERALL IMPRESSION OF
THE REPORT? 
This case report of distal colonic and Rectal occult GI bleeding in a 9 year old
with KTS is informative, educational, and gives important information to
physicians as well as gastroenterologist and GI surgeons about potential GI
bleeding in these patients to with KTS. 
ARE YOU CONFIDENT IN THE AUTHORS' DESCRIPTION AND
INTERPRETATION OF THE REPORT? 
Yes totally
HAVE THE AUTHORS CLEARLY OUTLINED THE NEED FOR
PUBLICATION BY NOVELTY OF THE CASE OR THE SPECIFIC
ADVERSE EVENT? 
The authors have made a great case for publishing this unusual complication in
patients with KTS. This condition is rare and most internists do NOT have a
great experience with its management . Similarly, gastroenterologist also would
benefit reading this educational case report
REQUESTED REVISIONS: 
SUGGESTED CHANGES
please note My suggestions area all minor. 
I want to congratulate the authors on
a well written, concise case report with only the important data presented-- well
done !
1. Lines 61-63. Please give the duration of follow up and what hemostasis
treatments were given
2. Line 80 please give a bit more information concerning the angiographic
embolization. Does this involve selective embolization of feeding vessels or
embolization of the inferior mesenteric artery supply to the sigmoid colon itself
maybe a statement about the extent of operative treatment needed 
should the
rectal bleeding be unable to be managed conservatively, i.e, total proctectomy
ileoanal pull through procedure , etc
ADDITIONAL REQUESTS/SUGGESTIONS: 
see above
