Abstract

An adequate bowel preparation in patients with inflammatory bowel disease (IBD) is a prerequisite for successful colonoscopy for screening, diagnosis, and surveillance. Several bowel preparation formulations are available, both high- and low-volume based on polyethylene glycol. Generally, low-volume formulations are also based on several compounds such as magnesium citrate preparations with sodium picosulphate, oral sulphate solution, and oral sodium phosphate-based solutions. Targeted studies on the quality of bowel preparation prior to colonoscopy in the IBD population are still required, with current evidence from existing studies being inconclusive. New frontiers are also moving towards the use of alternatives to anterograde ones, using preparations based on retrograde colonic lavage.

Core Tip: Obtaining adequate bowel preparation is challenging when treating a patient with inflammatory bowel disease (IBD) undergoing colonoscopy. Colonoscopy has multidimensional value ranging from diagnosis to disease surveillance and cancer screening. Although numerous data are available on bowel preparations in the general population, it is still unclear which preparation is the best for both efficacy and safety in patients with IBD. In addition, the factors that increase the risk of suboptimal preparation in IBD patients remain unclear.
