Guideline for laparoscopic gastrectomy for gastric cancer (2023 edition)

Minimally invasive surgical techniques, represented by laparoscopic techniques, are currently an important tool in the surgical treatment of gastric cancer. With the development of more and more high-quality clinical research and the publication of results in recent years, the indications for laparoscopic techniques in the surgical treatment of gastric cancer have received more evidence-based medical support and have been actively explored in many aspects, such as patients receiving neoadjuvant treatment and patients with advanced gastric cancer receiving trans-lational treatment. In addition, laparoscopic gastric cancer surgery has made great progress in lymph node dissection and surgical resection scale, total laparoscopic surgery, pylorus-preserving gastrec⁃tomy, gastrointestinal reconstruction after proximal gastrectomy, and lymph node tracing. Based on the Guideline for Laparoscopic Gastrectomy for Gastric Cancer (2016 Edition), and combined with recent research hotspots and high-grade evidence-based medical results, the Guideline for Laparoscopic Gastrectomy for Gastric Cancer (2023 Edition) is revised and updated based on clinical evidence and oriented to clinical problems.
