PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: The revised manuscript is an improvement. The
authors have tried to answer the questions of Reviewer 2. They however have
not completely provided satisfactory answers. In the first correction, the
operation may be better described as ' laparoscopic ileocecal resection after high
ligation of the ileocolic artery with removal of nodes along the artery and it's
branches '. The other correction should state the controversy of choice of
operation and include the options (with references) and state the reasons for their
choice. 
Other areas that needs improvements include the definition of true
diverticulum. The use of ' herniation' may be inappropriate. The authors were
also completely silent about the regional lymph nodes during pre operative
assessment, postoperative specimen and histology.
REQUESTED REVISIONS: 
1st correction may be better as' laparoscopic ileocecal resection after high
ligation of the ileocolic artery with removal of nodes along the artery and it's
branches '. 2nd correction should state the different operations recommended in
the controversy regarding treatment ( with references) and the reasons for their
choice. Other areas include their definition of true diverticulum where the use of
herniation may be inappropriate. The authors were completely silent on the
regional lymph nodes in the preoperative assessment, postoperative specimen
and histology.
