[Exploration of gasless laparoscopic gastric cancer surgery].

Abstract

Laparoscopic technology has been widely used in the surgical treatment of gastric cancer, but the operating space inside the abdominal cavity is mostly created by CO₂ artificial pneumoperitoneum. There is a paradoxical result of CO₂ artificial pneumoperitoneum, which may increase the risk of complications in elderly patients with poor cardiopulmonary function. Therefore, people have been trying non pneumoperitoneum techniques. This article focuses on the establishment of CO₂ pneumoperitoneum as the core technology of minimally invasive abdominal surgery in laparoscopic minimally invasive techniques both domestically and internationally over the years, as well as the complications caused by CO₂ artificial pneumoperitoneum. It explores the use of "no pneumoperitoneum" in minimally invasive abdominal surgery and summarizes the exploration of the author's center in this field. The article also looks forward to the prospects of this technology.
