Efficacy of robot-assisted thoracoscopic surgery for managing thymoma recurrence following sternotomy: a case report

This report addresses the management strategy and effectiveness of robot-assisted thoracoscopic surgery (RATS) for treating local recurrence of thymoma, a condition often complicated by severe adhesions and limited data on re-operation following median sternotomy. We report about a 43-year-old man with thymoma recurrence 4 years after thymothymectomy via a median sternotomy. Follow-up computed tomography revealed a nodule adjacent to the left brachiocephalic vein, indicating possible thymoma recurrence. Thus, re-operation was performed using a left-sided approach via RATS with an artificial pneumothorax. The manipulation space was secured with an artificial pneumothorax, and multidirectional manipulation using RATS demonstrated good efficacy. Collectively, this case highlights the efficacy of RATS as a viable approach for managing thymoma recurrence in mediastinal locations, particularly when sternotomy is complicated by severe adhesions.
