Clinical Trial Summary

The purpose of this study is to explore the clinical outcomes of the robotic distal gastrectomy for patients with gastric adenocarcinoma（cT1-4a, N-/+, M0）.

Description:

Robotic surgery has been developed with the aim of improving surgical quality and overcoming the limitations of conventional laparoscopy in the performance of complex mini-invasive procedures. The study is designed to explore the clinical outcomes of the robotic distal gastrectomy by comparing short- and long-term outcomes including financial cost of robotic and laparoscopic distal gastrectomy in the treatment of gastric adenocarcinoma （cT1-4a, N-/+, M0）.

Intervention

Procedure:
• Robotic Distal Gastrectomy
After exclusion of T4b, bulky lymph nodes, or distant metastasis case, robotic distal gastrectomy will be performed in the experimental group.
• Laparoscopic Distal Gastrectomy
After exclusion of T4b, bulky lymph nodes, or distant metastasis case, laparoscopic distal gastrectomy will be performed in the comparator group.
