Abstract:

With the development of precision diagnosis and treatment and minimally invasive concepts, the treatment strategies for gastric cancer have gradually diversified and refined, but for patients with advanced gastric cancer, radical surgical resection is still the key process in the treatment. With the promotion and application of laparoscopic technology, laparoscopic total gastrectomy has been widely carried out in tertiary hospitals across China. Therefore, only a detailed and complete set of surgical lymph node dissection strategies for gastric cancer can be developed to guarantee the quality of laparoscopic gastric cancer surgery in hospitals of all levels. Laparoscopic total gastrectomy requires multi-level and multi-space separation and dissection around the stomach, accurate naked dissection of perigastric blood vessels, and thorough dissection of perigastric lymph nodes, in order to ensure the radical operation. The dissection of perigastric lymph nodes is usually divided into five regions: subpyloric region, suprapancreatic region, suprapyloric region, splenic hilum region and cardiac region. In the process of cleaning each area, the tacit cooperation of the surgeon, the assistant and the mirror holder is required to ensure the smooth progress of laparoscopic total gastrectomy lymph node dissection.
