Natural Chromoendoscopy for Detecting Colorectal Polyps

In this episode we discuss using natural color changes called "biologic chromoendoscopy" to detect challenging flat colorectal lesions. Key Topics Discussed: - While sessile and pedunculated polyps are easy to spot endoscopically, flat and serrated lesions are challenging - AI, virtual chromoendoscopy, and dyes aren't reliable for flat lesions obscured by mucus/debris - Mucus changes light penetration, traps stool, and creates a hazy appearance - Two mucin secretion changes: lost O-acetyl g...
