The thoroughness of lymph node dissection is an important prognostic factor for patients with advanced gastric cancer. Splenic lymph node dissection is required during D2 radical gastrectomy for upper stomach cancer. This is often accompanied by removal of the spleen in the past few decades. A growing number of investigators believe, however, that the spleen plays an important role as an immune organ, and thus they encourage the application of a spleen- preserving method for splenic hilum lymph node dissection.展开更多

Dissection of the station 10 splenic lymph nodes is required in the treatment of advanced proximal gastric cancer. Based on vascular anatomy and anatomical plane of fascial space, integrated with our experience in station 10 splenic lymph node dissection in open surgery and proven skills of laparoscopic operation, we have successfully mastered the surgical essentials and technical keypoints in laparoscopic-assisted station 10 lymph node dissection.展开更多
