Bowel preparation for colonoscopy: what is best and necessary for quality?

PURPOSE OF REVIEW

Colonoscopy is recognizably, the best colon cancer prevention test, provided the quality of the preparation is adequate for detection of precancerous polyps but also allowing for accurate identification of margins, thereby facilitating complete endoscopic resection. As there are many aspects effecting colon prep outcomes, it is timely to review new standards for optimizing outcomes, including product selection based on patient demographics.

RECENT FINDINGS

New national guidelines have set a minimum quality threshold for adequacy and also defined a split day delivery for oral options as the "standard of care". Several new prep options have been recently released and these data are discussed.

SUMMARY

Optimizing the quality of colon preps has major implications for clinical practice. Clinicians must recognize new targets for standard of care, providing the best approach for each individual patient, considering variable factors which may otherwise compromise success.
