[A voice-controlled robot assisted thoracoscopic surgery for pulmonary tumor]

We herein report a case of voice-controlled robot assisted thoracoscopic surgery for a right apical tumor in a 55-year-old male. The patient was referred to our hospital for further examination of an abnormal shadow on chest X-ray. A chest computed tomographic scan indicated a suspicion of malignancy. Thoracoscopic surgery using a voice-controlled robot was conducted. The thoracoscope connected with the robotic arm was inserted through the trocar. In all maneuvers (forward and backward, right and left, up and down, insertion and extraction), the robotic arm moved appropriately immediately after the voice commands were issued, and favorable operative fields were obtained. Thoracoscopic partial resection of the involved lung was successfully performed with no complications. The operative time was 140 min. The postoperative course was uneventful. Voice-controlled robotic technology innovations may become the operating surgeon's third arm in the future. They will be further used not only in laparoscopic but also in thoracoscopic surgical procedures. Regular use will lead to greater skill in thoracoscopic application with the advent of new robotically assisted endoscopic surgery.
