RESUMO
Complete excision of the left gastroepiploic mesentery and complete dissection the No.4sb lymph nodes is the entrance and one of important steps of splenic hilar lymph node dissection. 4K laparoscopy has a higher level of surgical vision and more subtle degree of local anatomical recognition.Following the concept of mesentery anatomy and with the help of the unique advantages of 4K laparoscopy, the lymph node dissection of left gastroepiploic region is more thoroughly, the operation time is shorter, and there is no bleeding or micro-bleeding. At the same time, the maximum protection of the surrounding important organs and blood vessels, can further improve the radical and safety of the operation. The authors investigate the lymph node dissection along the left gastroepiploic vessels region from intermediate approach in 4K laparoscopic radical gastrectomy.
