we found that the following principles were important in maximizing the value of this technique : ( 1 ) good communication between the endoscopist and operating surgeon during the procedure , ( 2 ) clamping the distal small bowel to prevent air accumulation in the colon ( 3 ) examining the bowel on the way in and avoiding the use of suction to minimize scope trauma artifact , ( 4 ) turning off the room lights in order to examine the transilluminated bowel externally , ( 5 ) examining the entire small bowel if possible , and ( 6 ) marking each site externally with a suture as it is identified .
