Precision application and evaluation of high‑precision laparoscopic imaging technology in minimally invasive gastric cancer surgery

High‑precision laparoscopic imaging is an emerging laparoscopic technology platform in recent years, which mainly includes 3D laparoscopy, 4K ultra‑high definition laparoscopy, and indocyanine green (ICG) near‑infrared fluorescent imaging. In minimally invasive gastric cancer surgery, these technologies can reconstruct a more realistic and intuitive three‑dimensional structure, precisely locate the tumor and perigastric lymph nodes, and thus clearly expose the anatomical levels, facilitating laparoscopic surgical operations such as perigastric vascular nudity, lymph node dissection and digestive tract reconstruction. The authors discuss the latest advances in high‑precision laparoscopic imaging technology in minimally invasive gastric cancer surgery, together with the practical experience of the author′s team and relevant domestic and international literature, and analyze the advantages and challenges of this technology in clinical application, intending to promote the popularization of high‑precision laparoscopic imaging technology in minimally invasive gastric cancer surgery.
