[Choice of function-preserving gastrectomy].

As the diagnosis rate of early gastric cancer is increasing annually, the current hot spot in the treatment of early gastric cancer is how to better preserve the anatomical structure and physiological function of the stomach and improve the quality of life of patients after surgery under the premise of tumor eradication. Therefore, function-preserving gastrectomy has been the trend of surgical treatment for early gastric cancer. It is not just a modified gastrectomy, but a better combination of improved surgical techniques and the concept of function-preserving treatment, rather than being limited to traditional surgical treatments. Currently, the routine function-preserving gastrectomy mainly includes pylorus-preserving gastrectomy, proximal gastrectomy and partial gastrectomy combined with endoscopy. In addition, with the deeper understanding of metastasis pattern of gastric cancer and the development and popularization of minimally invasive techniques, laparoscopic and endoscopic cooperative surgery is gradually gaining attention. The application of laparoscopic and endoscopic hybrid surgery combined with sentinel lymph node navigation is anticipated in the treatment of early gastric cancer.
