Station 10 lymph node dissections in laparoscopic-assisted spleen-preserving radical gastrectomy for advanced proximal gastric cancer.

D2 gastric resection has been increasingly recognized as the optimal surgical treatment for advanced gastric cancer. 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.
