Enhancing Diagnostic Accuracy of Sinonasal Lesions: The Role of Narrow Band Imaging in Differentiating Inverted Papillomas from Nasal Polyps

Narrow-band imaging (NBI) significantly improves the endoscopic differentiation of inverted papillomas (IPs) from nasal polyps (NPs) by highlighting mucosal microvasculature patterns, achieving superior diagnostic accuracy compared to white-light endoscopy (WLE). Combining NBI with WLE further enhances preoperative lesion assessment.

Location Alone Shouldn’t Drive ESD: French Registry Finds Similar Submucosal Cancer Rates in Large Rectal and Colonic Non‑Pedunculated Polyps

A multicentre French ESD registry found that, after adjusting for size and morphology, large non‑pedunculated rectal polyps do not have higher rates of submucosal invasive cancer than equivalent colonic lesions; technical outcomes of ESD were comparable, with a trend to higher complications in the colon.
