Stimulation of colonic motility by oral <scp>PEG</scp> electrolyte bowel preparation assessed by <scp>MRI</scp> : comparison of split <i>vs</i> single dose

Abstract

Ingestion of 1 and 2 L PEG electrolyte solution caused a rapid increase in the small bowel and colonic volumes and a robust rise in colonic motility. The increase in both volumes and motility was dose dependent. Such a challenge, being well-tolerated, could be a useful way of assessing colonic motility in future studies.
