Complete anterior–posterior minimally invasive thoracoscopic robotic-assisted and posterior tubular approach for resection of thoracic dumbbell tumor

Thoracic dumbbell tumors are relatively uncommon neoplasms that arise from the neurogenic elements. Surgical resection can be challenging as the tumor involves both the spinal canal and thoracic cavity. Historically, thoracotomy and laminectomy were utilized for the resection of these tumors. Although single-stage removal of such tumors has been described recently, there is no prior description of a total minimally invasive single-stage resection of a thoracic dumbbell ganglioneuroma. The current report describes a completely minimally invasive surgical resection for such a tumor performed using the posterior minimally invasive tubular approach to resect the intraspinal component with ligation of the T2 nerve root in conjunction with robotic-assisted thoracoscopic resection of the extraforaminal, intrathoracic component of the tumor. This report illustrates the safety and utility of a completely minimally invasive endoscopic resection of a thoracic dumbbell tumor that can potentially obviate the morbidity associated with open surgical resections for such tumors.
