Editorial: A light breakfast, a jug of salt water, and bowel.

Successful colonoscopy is predicated on achieving adequate colon cleansing. An ideal bowel preparation would be low in volume, acceptable to patients, reliable in cleansing efficacy, and safe. The study by Di Palma et al. in this issue shows that a novel, low-volume (960 ml) preparation of mixed sulfate salts can achieve excellent bowel cleansing with acceptable tolerability and minimal electrolyte shifts. A split-dosing strategy, with a proportion of the preparation administered on the day of colonoscopy, achieved a 97.2% preparation success rate vs. 82.4% using a regimen provided entirely the day before colonoscopy. These results were comparable with control groups using a commercially available polyethylene glycol solution. Endoscopists and patients alike should be encouraged by the trend toward lower-dose bowel cleansing regimens that achieve equivalent efficacy compared with large-volume preparations.
