Study on the Efficacy and Safety of Enhanced Recovery After Surgery （ERAS）in Gastrointestinal Cancer

At present, there are more and more reports about enhanced recovery after surgery（ERAS）in China, but there is no ERAS treatment standard for gastrointestinal cancer, and there are many factors limiting the development of ERAS. In recent years, due to the development of minimally invasive technology, the establishment of evidence-based medicine model and the development of MDT, it makes a good solid foundation for the clinical application of ERAS. The implementation of ERAS requires the cooperation of surgeons, anesthesia management, nursing, rehabilitation and other teams. As an individualized treatment mode, ERAS focuses on the optimization of treatment for different individuals in order to acquire the best benefit of patients. Therefore, the concept of ERAS is still in the process of continuous improvement and development in China, hoping to explore the Chinese ERAS clinical pathway for gastrointestinal cancer. The purpose of this study is to optimize the clinical pathway of ERAS in the perioperative period of gastrointestinal cancer, and to evaluate the effectiveness and safety of ERAS in gastrointestinal cancer.
