Robot-assisted Thoracoscopic Resection of a Benign Mediastinal Neurogenic Tumor: Technical Note

摘要

OBJECTIVE: Robotic surgery systems were introduced recently with the objective of enhancing the dexterity and view during procedures that use a videoscope. The first case report of robot-assisted thoracoscopic removal of a benign neurogenic tumor in the thorax is presented. METHODS: A 46-year-old woman presented with a history of paravertebral pain. A chest x-ray revealed a left paravertebral mass. A magnetic resonance imaging scan revealed a well-encapsulated mass that was suspected to be a neuroma at the level of T8-T9, separate from vascular structures, without extension in the foramina, and without a spinal canal component. RESULTS: A left robot-assisted thoracoscopic resection of the tumor was performed. After placement of six trocars, the tumor was carefully dissected and removed through one of the trocar openings. The histopathological findings revealed an ancient schwannoma. CONCLUSION: This case report demonstrates the feasibility of robot-assisted thoracoscopic extirpation of a thoracic neurogenic tumor. Robot-assisted surgery may prove to be of additional value in challenging thoracoscopic surgery, such as the delicate surgical removal of benign neurogenic tumors, because of the support in manipulation and visualization during videoscopic interventions.
