Performance of artificial intelligence for colonoscopy regarding adenoma and polyp detection: a meta-analysis.

Gastrointestinal Endoscopy, 2020
BACKGROUND AND AIMS One fourth of colorectal neoplasia is missed at screening colonoscopy, representing the main cause of interval colorectal cancer (CRC). Deep learning systems with real-time computer-aided polyp detection (CADe) showed high accuracy in
