[Development status and prospects of functional preservation surgery for gastric cancer].

Function-preserving surgery for gastric cancer is a treatment strategy aimed at improving postoperative function while ensuring oncological safety. By preserving important anatomical structures such as the cardia, pylorus, and vagus nerve, as well as key functions like digestion, secretion, emptying, and anti-reflux, this approach aims to minimize the negative impact on patients' postoperative quality of life. With the widespread application of neoadjuvant treatment and the continuous improvement in the efficacy of anti-tumor drugs, the application and indications for functional-preserving surgery may further expand. This article reviews the current status and future prospects of function-preserving surgery for gastric cancer, focusing on its main types, applications after neoadjuvant therapy, and the exploration of new technologies.
