The patients underwent robotic radical gastrectomy (total gastrectomy and D2 lymph node dissection with Roux-En-Y anastomosis) under static inhalation combined anesthesia. Lymph node dissection and digestive tract reconstruction were all performed under the lens. The operation time was 205 minutes, and the intraoperative blood loss was 65ml. Postoperative pathology: middle-low differentiated adenocarcinoma of the small curvature of the stomach, infiltrating into the whole gastric wall, with nerve invasion, no involvement of the upper and lower resection margin and greater omentum. Metastasis of lymph nodes were of 8/26 within small curvature of the stomach, and were of 4/11 within large curvature of the stomach. The patient was discharged from the hospital on the 4th day after the operation, and the perioperative treatment was conducted under the guidance of the concept of accelerated rehabilitation surgery.
