[Technical challenges and preventive countermeasures of robotic gastric cancer surgery]

Over the past two decades, the surgical treatment of gastric cancer has witnessed remarkable transformations. It has evolved from traditional open - surgery to laparoscopic minimally - invasive surgery, and subsequently to robot - assisted surgery. The robotic surgical system, owing to its distinctive advantages, has been gradually applied and popularized in gastric cancer surgeries. Nevertheless, it inevitably gives rise to specific technical blind spots and operational challenges.This paper systematically reviews the classification of intraoperative errors in robotic gastric cancer surgery and their clinical implications. It proposes a grading standard for bleeding, explores the identification and prevention strategies of hazard zones, and underscores the core values of meticulous preoperative planning, the standardized operation, and teamwork. Simultaneously, in light of the impact of tissue edema and fibrosis following neoadjuvant therapy on surgery, corresponding grading standards are established. The objective is to offer a valuable reference for clinical practice and facilitate the standardized and precise development of robotic gastric cancer surgery.
