Single-port Robotic Radical Gastrectomy for Gastric Cancer

Summary

This study is a single-center, phase 2a exploratory clinical study based on IDEAL framework. The intraoperative and postoperative complications were analyzed to evaluate the safety, feasibility and clinical efficacy of single-port robot-assisted gastric tumor resection.
