Core Tip
Core tip: Discarding a polyp without performing histological evaluation runs the risk of failing to detect small invasive colorectal cancer. Retrospectively, we aimed to assess the risk of failing to detect diminutive and small colorectal invasive cancer with the “resect and discard” strategy by using the NICE classification scheme with a magnifying endoscope. We reviewed and assessed 878 polyps less than 1 cm in diameter detected in our hospital. Among them, 2 SM-d carcinomas were found and both of their optical features were classified as NICE type 3. We concluded that the risk of failing to detect diminutive and small invasive colorectal cancer with the “resect and discard” strategy might be prevented by employing NICE classification under narrow-band imaging magnification.
