MS Versus NICE for Colorectal Lesions

Prospective Randomised Study Comparing Modified Sano's (MS) Classification and NBI International Colorectal Endoscopic (NICE) for Differentiating Colorectal Lesions

OBJECTIVE: Our study aimed to compare a recently-developed endoscopic classification with an established one for colorectal lesions in a randomised trial between 2013 and 2015.

OBJECTIVE: Current practice requires histopathological assessment to confirm diagnosis for colorectal lesions detected at colonoscopy. Advances in endoscopic imaging contribute for real-time diagnosis which, apart from being cost and time-saving, also guides decision-making and reduces risks. Our study aimed to compare a recently-developed endoscopic classification with an established one.

DESIGN: The modified Sano's classification (MS) was compared to the Narrow Band Imaging (NBI) International Colorectal Endoscopic classification (NICE) in a randomised trial between 2013 and 2015. An experimented endoscopist classified each polyp, what was compared to histopathology.

Inclusion Criteria:

• Patients admitted in the Endoscopy Unit for a colonoscopy
• Patients over 18 years-old
• Patients or their caregivers that have understanding of the procedure and that have signed the consent form for the study

Exclusion Criteria:

• Patients without colorectal polyps
• Patients with poor bowel preparation
• Patients that do not agree with or withdraw the consent form
