Reviewer's report:  
This paper is dealing with an old topic. This may be is new in Thailand. Unfortunately the 
number of patients is small for such analysis. There is also some misunderstanding. In the text  is 
written that the group of patients selected for colonoscopy did not present any symptoms from 
the alimentary tract. In the table there is listed small group of them, which had the symptoms. 
There is a question if in this group there was another finding  that in the other group. There is also 
similar issue. In the text there is written that the patients did not have any family history of CRC 
but in the table there is shown a group of patients with the history of family CRC. There is also 
no information in  this paper if this group of patients had any other findings in the colonoscopy.  
The findings in this paper are well known and there is nothing new in this paper so I leave the 
decision to the Chief -Editor
