Robot-assisted vs VATS for Thymoma

Summary

The aim of this study is to explore the advantages of robot-assisted thymectomy in long-term survival benefits and short-term clinical efficacy compared with video-assisted thoracoscopic thymectomy based on a multi-center, prospective, randomized controlled clinical trial.
