摘要
Artificial intelligence(AI)allows machines to provide disruptive value in several industries and applications.Applications of AI techniques,specifically machine learning and more recently deep learning,are arising in gastroenterology.Computer-aided diagnosis for upper gastrointestinal endoscopy has growing attention for automated and accurate identification of dysplasia in Barrett’s esophagus,as well as for the detection of early gastric cancers(GCs),therefore preventing esophageal and gastric malignancies.Besides,convoluted neural network technology can accurately assess Helicobacter pylori(H.pylori)infection during standard endoscopy without the need for biopsies,thus,reducing gastric cancer risk.AI can potentially be applied during colonoscopy to automatically discover colorectal polyps and differentiate between neoplastic and nonneoplastic ones,with the possible ability to improve adenoma detection rate,which changes broadly among endoscopists performing screening colonoscopies.In addition,AI permits to establish the feasibility of curative endoscopic resection of large colonic lesions based on the pit pattern characteristics.The aim of this review is to analyze current evidence from the literature,supporting recent technologies of AI both in upper and lower gastrointestinal diseases,including Barrett's esophagus,GC,H.pylori infection,colonic polyps and colon cancer.
