Gut, 74(1), 35-44. https://doi.org/10.1136/gutjnl-2024-332755

Background
Colonic motility in constipation can be assessed non-invasively using MRI.

Objective
To compare MRI with high resolution colonic manometry (HRCM) for predicting treatment response.

Design
Part 1: 44 healthy volunteers (HV), 43... Read More about Combined magnetic resonance imaging, high resolution manometry and a randomised trial of bisacodyl versus hyoscine shows the significance of an enlarged colon in constipation: the RECLAIM study.

Background: Lactulose is a laxative which accelerates transit and softens stool. Our aim was to investigate its mechanism of action and use this model of diarrhea to investigate the anti-diarrheal actions of ondansetron.
Methods: A double-blind, ra... Read More about Mechanisms underlying the laxative effect of lactulose: A randomized placebo‐controlled trial showing increased small bowel water and motility unaltered by the 5‐HT3 receptor antagonist, ondansetron.
