摘要Deep learning has made tremendous progress in diagnosis assistance and prognosis prediction along with the accumulation of abundant medical data and the improvement of computer al-gorithms.Many studies have focused on applying deep learning to diseases of the lower gastrointesti-nal tract.Studies on deep learning and digestive system diseases mainly focus on cancer and inflamma-tory diseases,while few studies focus on other diseases.In order to better understand the emerging interdisciplinary,this paper reviews the ways in which deep learning may help doctors make a diagno-sis or establish a prognosis,revealing that further randomized controlled studies and deeper coopera-tion between artificial intelligence engineers and doctors will be required.
