Core Tip

Core tip: This is the first meta-analysis addressing the issue of bowel preparations in Inflammatory bowel disease (IBD) patients aiming to determine any differences in terms of effectiveness, safety and tolerability between existing colon-cleansing products. This work is especially timely considering that colonoscopy is used frequently in IBD patients for both diagnosis and surveillance, and that recommendation on how to prepare these patients prior to colonoscopy are based mostly on expert opinion. The results suggest that low-volume polyethylene glycol (PEG) preparation with adjuvants in split-dosing may represent a valid alternative to standard high-volume PEG with at least a similar efficacy and better acceptability.
