Summary

This study will compare two strategies for colonoscope withdrawal, using polyp detection as the primary outcome measure, to determine the optimal withdrawal strategy.

Null Hypothesis:

On withdrawal of the colonoscope, examining patients with dynamic position change does not yield more polyps than the supine position.

Alternative Hypothesis:

On withdrawal of the colonoscope, examining the patients with dynamic position change improves polyp detection compared to the supine position.

Conditions

  • Intestinal Polyps

Interventions

PROCEDURE

Strategy : Supine first

The initial withdrawal in each of 4 segments of the colon: 1)Caecum, Ascending colon and Hepatic flexure 2) Transverse colon 3) Splenic flexure and descending colon 4) Sigmoid colon, will be performed in two different positions. The intervention in this arm will be withdrawal in the supine position and then with dynamic position change.

The intervention in this arm will be withdrawal with dynamic position change first followed by the supine position.
