Title: 
Small intestine duplication cyst with recurrent hematochezia: a case report
and literature review

Reviewer's report:
Dear author,
It was a pleasure for me to review your study related to SIDC; a rare case and
review of the literature. I must say it is a well organized and structured
manuscript.
Still I have two small points I assume to be changed:
1) You stated that you performed capsule endoscopy two times safely and it
helped a lot. Here I assume we have to give and warn the readers about the
contraindications of capsule endoscopy e.g intestinal obstruction (it is not the
clinical presentation in the current case but intestinal obstruction may be 
a
clinical representatin in some SIDC patients) may result in capsule retention.
2) Second minor thing is about figure two in which surgical specimen is
demonstrated. It will be nice if you use an arrow showing Dublication cyst and
ileocecal valve if possible.
Thank you for your submission
