简要总结

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.

详细描述

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.

结局指标

主要结局

Accuracy measures in comparison to the final histopathology in regards to polyps' invasiveness

时间窗: After two weeks of the colonoscopy

Comparison of NICE or MS with the final histopathology in regards to invasiveness (SSA/P, AP, TSA or superficial cancer versus invasive cancer)

Accuracy measures in comparison to the final histopathology in regards to polyps' subtype (neoplastic versus non-neoplastic)

时间窗: After two weeks of the colonoscopy

Comparison of NICE or MS with the final histopathology in regards to polyps' subtype (i.e. non-neoplastic = Hyperplastic Polyp (HP) and neoplastic = Sessile Serrated Adenoma/Polyp (SSA/P), Adenomatous Polyp (AP), Traditional Serrated Adenoma (TSA), superficial cancer and invasive cancer)

Accuracy measures in comparison to the final histopathology in regards to polyps' subtype (SSA/P versus non-SSA/P)

时间窗: After two weeks of the colonoscopy

Comparison of MS with the final histopathology in regards to SSA/P (SSA/P versus non-SSA/P)

次要结局

  • Accuracy in regards to negative predictive value of diminutive distal colorectal polyps(After two weeks of the colonoscopy)
  • Agreement in predicting post-colonoscopy surveillance interval with final histopathology(Immediately after the colonoscopy (endoscopic) and 2 weeks after (histopathology))
