Abstract: In recent years, the detection rate of early gastric cancer in China has increased. Early gastric cancer has a good prognosis, and how to further improve the postoperative quality of life for patients has become an increasingly concerned problem in the treatment of early gastric cancer. Therefore, function preserving gastrectomy has emerged. Function preserving gastrectomy aims to reduce the resection scope and preserve part of the gastric function on the premise of radical tumor resection. As a representative of function preserving gastrectomy, pylorus‑preserving gastrec-tomy is suitable for early gastric cancer in middle segment. Compared with distal gastrectomy, laparoscopic pylorus‑preserving gastrectomy not only has the advantage of less trauma, but also can reduce the incidence of postoperative dumping syndrome, bile reflux gastritis and gallstones, and improve postoperative nutritional status. However, the practice of pylorus‑preserving gastrectomy is still in controversial. Based on the new Japanese guidelines for the treatment of gastric cancer, and combined with the latest domestic and foreign research trends and relevant evidence‑based medicine basis, the authors review the definition and indications, safety, advantages, technical points, digestive tract reconstruction methods, postoperative complications and other aspects of laparoscopic pylorus-preserving gastrectomy.
