Gastric cancer is a prevalent malignancy of the digestive system, and traditional laparoscopic radical gastrectomy remains a crucial treatment modality. However, the abdominal wound associated with specimen removal during this procedure conflicts with contemporary concept of minimally invasive surgery. Natural orifice specimen extraction surgery (NOSES) is an emerging minimally invasive surgical technique that has gained increasing utilization in patients with gastrointestinal tumors, owing to its benefits of reduced wound, accelerated postoperative recovery, and diminished postoperative pain. In recent years, the extensive application of NOSES technology for colorectal cancer in China has provided theoretical support for the minimally invasive treatment of gastric cancer. With the standardization of community health examinations in China, the incidence of early gastric cancer diagnoses is expected to rise, making NOSES surgery the likely future trend in the surgical treatment for early gastric cancer. However, this area remains under-explored both domestically and internationally. This paper aims to synthesize prior literature and review the historical development, current research status, advantages and disadvantages, technical challenges, and future directions of completely laparoscopic radical treatment of distal gastric cancer utilizing NOSES.
