Abstract: With the rise of the digital era, various digital technologies, including three-dimensional printing, reconstruction, and visualization, have been widely applied in medicine, particularly in surgery, advancing medical development and innovation. Digital technology and precision medicine have advanced with the development and application of artificial intelligence (AI), leading to diverse innovations in the field of surgery. Digital technology has also facilitated new approaches in precision medicine, enabling the precise localization of lesions before surgery, real-time intraoperative navigation, and the establishment of predictive models for postoperative outcomes. These advancements have thus driven the comprehensive transformation of surgical practice toward greater personalization, precision, and intelligence. This study provides a comprehensive review of the application of digital technologies in gastrointestinal tumor management, encompassing preoperative planning, intraoperative navigation, and postoperative recovery. The evolution of digital technologies is described, and an in-depth summary is provided of the development and clinical value of digital technology in gastrointestinal tumor surgery. Additionally, the study proposes future directions for digital medicine in this field.
