Brief summary

There was an only single operator study reporting dynamic position change during colonoscopy withdrawal significantly improved polyp and adenoma detection. So we designed a prospective, randomized multicenter study to verify the effect of dynamic position change in colonic adenoma detection. We think position change improve luminal distension and has the potential to improve adenoma detection rate.

Interventions

PROCEDUREPosition change

Patients change position (cecum to hepatic flexure, left lateral; transverse colon, supine; splenic flexure and descending colon , right lateral) during colonoscopy withdrawal.

PROCEDURELeft lateral

In left lateral position group patients are positioned left lateral decubitus during colonoscopy withdrawal.
