Single-Port Robotic Thymectomy Expands Options in Myasthenia Gravis

Key Takeaways

• Thymectomy with a beneath-the-sternum single-port approach was associated with less postoperative and neuropathic pain than multiport rib-based access.
• Early patient experiences have been encouraging, but comparative recovery outcomes are still being studied.

A single-port robotic approach to thymectomy is expanding treatment options for patients with myasthenia gravis at the University of Miami. Performed through a single incision beneath the sternum, the technique is designed to avoid the intercostal nerves that can be affected during traditional multi-port robotic procedures, potentially improving postoperative comfort and recovery.

Dr. Nestor Villamizar became the first surgeon in the Miami area to perform the procedure last September. Since then, he has completed more than 120 operations using the single-port robotic platform.

Unlike conventional robotic thymectomy, which requires several ports placed between the ribs, the single-port approach uses one entry point beneath the sternum. Technique avoids intercostal nerve irritation associated with rib-based access, a factor that may contribute to postoperative neuropathic pain.

To better understand the procedure's impact on recovery, Villamizar is leading a study comparing outcomes between single-port and multi-port robotic thymectomy. Results from that analysis have not yet been released.
