Where is the difficulty of a myasthenia gravis patient operation 35 years ago?—“a comparison of robotic and transsternal early stage thymoma resection by Marulli”

I would like to thank the editors of new brand journal Mediastinum for requesting me to write an editorial about the manuscript by Marulli et al. “Comparing robotic and trans-sternal thymectomy (TST) for early-stage thymoma: a propensity score-matching study” (1), published in European Journal of Cardio-Thoracic Surgery (EJCTS) March, 2018 issue.
