Laparoscopic Versus Open Gastrectomy With Splenic Hilum Lymph Nodes Dissection

Laparoscopic Versus Open Total Gastrectomy With Spleen-preserving Splenic Hilum Lymph Nodes Dissection for Advanced Proximal Gastric Cancer: A Randomized Controlled Trial

Splenic hilum remains challenging during total gastrectomy with D2 lymphadenectomy.The application of minimally invasive surgery for advanced gastric cancer is gaining popularity. The investigators aim to compare the safety and feasibility of LTG and OTG for advanced proximal gastric cancer.

Detailed Description

Total gastrectomy with D2 lymphadenectomy remains the standard surgical therapy for patients with advanced proximal gastric cancer. Although lymph nodes dissection along with the splenic hilum (No.10) is recommended by the Japanese Gastric Cancer Treatment Guidelines, however, complete removal of the No. 10 is technically challenging due to the tortuous splenic vessels and the high possibility of injury to the parenchyma of the spleen and pancreas. Recently, the application of minimally invasive surgery for advanced gastric cancer is gaining popularity. However, laparoscopic total gastrectomy (LTG) with standard D2 lymphadenectomy was still not widely performed, because pancreas- and spleen-preserving splenic hilum lymph node dissection were mainly challenging manipulations for laparoscopic surgeons. Therefore,the investigators aim to investigate the safety and feasibility of LTG with spleen-preserving splenic hilum lymph node dissection for proximal advanced gastric cancer and compare the early results of this procedure with open total gastrectomy (OTG).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Laparoscopic total gastrectomy
Participants including in the laparoscopic total gastrectomy (LTG) group will undergo LTG with spleen-preserving splenic hilum lymph nodes dissection.
Procedure: Laparoscopic total gastrectomy
When the participants with advanced proximal gastric cancer are randomized in the laparoscopic totalgastrectomy (LATG) group, they will received LTG with spleen-preserving splenic hilum lymph nodes dissection.
Other Names:
  • LTG
Active Comparator: Open total gastrectomy
Participants who are included in the open total gastrectomy (OTG) group will OTG with spleen-preserving splenic hilum lymph nodes dissection.
Procedure: Open total gastrectomy
When the participants with advanced proximal gastric cancer are randomized in the open total gastrectomy(OTG) group, they will received OTG with spleen-preserving splenic hilum lymph nodes dissection.
Other Names:
  • OTG
