Current status and advances in robotic function‑preserving gastrectomy

The robotic vagus nerve and pylorus-preserving gastrectomy (PPG) for early gastric cancer offers low invasiveness, high precision, and the benefits of maintaining optimal gastric func-tion and improving quality of life. As a representative function-preserving procedure for early gastric cancer,based on the concept of reducing resection, PPG preserves the pyloric function and vagus nerve and enhances gastric reservoir capacity and digestive absorption. The laparoscopic and robotic PPG have become the mainstream treatment for early gastric cancer in the middle and lower thirds of the stomach. Robotic surgery, distinct from open and laparoscopic approaches, leverages technical advantages such as three-dimensional magnified visualization and multi‑joint articulating instruments, enabling more precise and safer procedures. The author systematically elaborates on the current status and advances in robotic function‑preserving gastrectomy, and believes that as a novel surgical modality, robotic PPG effectively preserves gastric function, maintains normal gastro-intestinal digestion and absorption, and stabilizes postoperative body weight, thereby significantly improving patients′ quality of life.
