Core Tip
Core Tip: Dataset shift impairs non-inflammatory bowel disease (IBD) trained artificial intelligence’s (AI) ability in IBD dysplasia detection as they falter in inflamed colons and therefore IBD-specific models need to be developed. However, even with the IBD-trained models, various biases (selection, annotation, device) are seen which are amplified by training-deployment mismatches and affects generalizability as evident in external validation. This review compares performances, dissects these failures, and suggests a roadmap: Multicenter datasets, consensus labelling, federated learning, and multimodal models, bolstered by regulatory oversight and clinical workflows. Such integrated steps will help to generate equitable, reliable AI to enhance surveillance and avert colorectal cancer in IBD.
