With the promotion of health awareness and the improvement of gastroscopy examination technology, the detection rate of early gastric cancer in our country had gradually increased. The early gastric cancer had a favorable prognosis and long-term survival. Improving the postoperative quality of life of patients with early gastric cancer had become one of the important directions in gastric cancer research. Under the premise of ensuring tumor radical resection, preserving partial gastric remnant function had become a hot topic in the treatment of early gastric cancer. Function preserving gastrectomy for early gastric cancer mainly included segmental gastrectomy, proximal gastrectomy, and local gastrectomy, among others. The author summarized the important research progress in function preserving gastrectomy at home and abroad in recent years, as well as the practical experiences of this center, aiming to provide reference for clinical surgeons to better carry out this type of surgery.
