Abstract
The Da Vinci Surgical System is an ergonomically devised and excellent surgical support device. However, surgeon skill is of paramount importance since human error cannot be completely eliminated. We report a case of bleeding from the pulmonary artery due to a footswitch misstep. A 72-year-old male with suspected right upper lobe lung cancer underwent robot-assisted thoracoscopic surgery (RATS). While avoiding the pulmonary artery with the right arm spatula and trying to cauterize V2t with the left arm bipolar-forceps, the footswitch was accidently activated and the spatula was energized, resulting in pulmonary artery trauma and blood loss. After this case, we changed the surgical procedure from a monopolar-bipolar combination use to a bipolar-only use and noted no significant difference in the console duration, and less intraoperative blood loss. Human errors can occur anytime. Especially for surgeons new to RATS, simplified foot management should be considered until RATS mastery is achieved.
