Core Tip

Core Tip: Rectal neuroendocrine tumours (r-NETs) are increasingly detected during colorectal screening. Endoscopists may not accurately distinguish r-NETs from other polyps and inadvertent resection attempts result in significant post resection challenges. r-NETs have an unpredictable metastasis pattern, requiring appropriate pre-resection assessment. Accurate endoscopic assessment and resection provides an effective option in the management of r-NETs.
