Artificial Intelligence and Digital Innovation in Gastroenterology: Current Applications and Future Directions

This chapter critically examines the rapidly maturing application of artificial intelligence and machine learning in gastroenterology, with a focus on computer-aided detection and characterisation in endoscopy, AI-assisted histopathological diagnosis, natural language processing of clinical records, and predictive modelling in inflammatory bowel disease and hepatology. It evaluates the methodological foundations, regulatory landscape, and clinical validation of currently available AI tools, and offers a prospective assessment of how digital health technologies — including wearable sensors, remote patient monitoring, and precision medicine platforms — are poised to reshape gastroenterological practice and research.
