Details and patient eligibility

About

This study is to conduct a randomized controlled trial of two kinds of radical gastrectomy for patients with proximal gastric cancer. One is laparoscopic D2 radical total gastrectomy combined with spleen-preserving No.10 lymph node dissection , another one is laparoscopic D2 radical total gastrectomy without clearing the No. 10 lymph nodes of the spleen. We explore the effect of the two procedures on the survival of patients, as well as the surgical complications associated with the two procedures, the number of lymph node dissection, the operation time and the amount of intraoperative blood loss. Furthermore, we also want to discuss the application value of laparoscopic lymph node dissection for spleen preservation in radical gastrectomy for proximal gastric cancer.
