Clinical updates in bowel preparation for colonoscopy (ScienceDirect)

Up to 44% of colonoscopies still suffer from poor bowel prep — leading to missed lesions, longer procedures, and higher costs. In their latest review, Marcello Maida, Alexander D. Grieme, Yizhong Wu, and colleagues spotlight advances reshaping prep: from ultra-low-volume PEG regimens and split dosing <5 hours before procedures to AI-enabled prediction tools for personalizing prep. Even simple changes, like shifting from multi-day restrictions to a 1-day low-fiber diet, are boosting patient compliance. But risk factors like age, comorbidities, and socioeconomic barriers persist, leaving the field searching for sharper, more adaptive strategies.
