To investigate the feasibility，safety and short-term efficacy of functional preservation surgery for early gastric cancer.

The clinical data of 13 patients who underwent functional preservation surgery for early gastric cancer performed by the same surgical team from March 2021 to August 2022 were retrospectively analyzed.

All the 13 patients successfully completed functional preservation surgery，complete resection of tumors，operation time：［（183±25）min］，intraoperative blood loss：［（103±37）ml］，median lymph node dissection：11. Postoperative anal exhaust time：［（1.9±0.7）d］，defecation time：［（3.0±0.8）d］；Postoperative hospital stay：［（6.3±1.4）days］. Postoperative pathological report indicated that 1 case of lymph node pathology indicated cancer metastasis（2/14）. The basal margin was positive in 1 case. Postoperative gastric retention occurred in 1 patient who underwent PPG surgery and was discharged after conservative treatment after re-admission. Pathological results of 1 patient who underwent ESD+D1 lymph node dissection indicated carcinoma infiltration in the specimen base. Total gastrectomy was performed 2 months after discharge，and the pathological results of additional surgery were negative. The nutritional status and quality of life of patients were evaluated at 1 and 3 months after the follow-up. The results showed that all patients had a good quality of life and did not require additional nutritional support.

Functional preservation surgery for early gastric cancer accurately excizes the tumor lesion for the patient，preserves the function of the stomach to the maximum extent，has less trauma，fast recovery，and enables the patient to have a better quality of life after surgery. Therefore，it is safe and feasible to properly master the indications and surgical techniques of gastric function preservation surgery.
