Robotic Thymectomy (RT) at MLH

By Alicia McKelvey, MD, Thoracic Surgery

Traditionally, removal of the thymus gland (glandular tissue behind the sternum or breast bone) has required a sternotomy (splitting the sternum with a saw). Thymectomy is most often performed for removal of tumors/cysts in the thymus gland or to help neurologic symptoms of myasthenia gravis.

Robotic surgery is one minimally invasive technique (MIT) that has opened a new door to performing the same operation, but without a sternotomy. Other MIT approaches include unilateral or bilateral thoracoscopy, and transcervical thymectomy. The benefits of robotic thymectomy over other MITs include 3D visualization, wristed instruments giving a better range of motion, and no visible neck incision. Three or four one-inch incisions are created in either the left or right chest lateral to the breast. The benefits of this operation to patients include: faster recovery, less pain, and fewer days spent in the hospital.1 After undergoing a sternotomy, most people stay in the hospital 4 days on average. Patient activity is limited for up to 6 weeks, and most cannot drive for 4 weeks after the procedure.2 Robotic Thymectomy requires only an overnight stay in the hospital, and patients are often back to work within 2 to 4 days of their procedure.

Evaluation of robotic thymectomy shows it to be equivalent to open procedures for treatment of neurologic symptoms in patients with Myasthenia Gravis. This technique is safe for early stage thymomas.3 Indications for robotic approach for tumors include thymic lesions less than 8 cm in size without evidence of invasion into other structures and the ability of the patient to tolerate single lung ventilation.

 The Section of Thoracic Surgery at MLH offers this cutting edge approach to appropriate patients with thymic tumors and myasthenia gravis.
