内視鏡手術支援ロボットの使用経験

In Japan,１２ new operative robot-assisted endoscopic surgery methods were officially approved by the ２０１８ revision of the medical payment system, and robot-assisted endoscopic surgery is using in each field. We have used the pneumatically driven endoscope manipulator robot（EMAROⓇ）in three video-assisted thoracoscopic surgery（VATS）lobectomy cases : right upper lobe lung cancer in a ５３-year-old male, right lower lobe lung cancer in a ７０-year-old male, and right lower lobe lung cancer in an ８１-year-old female. The average operative time was ２０９ min. The average bleeding volume was ４６．７ml. The grades ware nearly equal to those obtained in a standard VATS lobectomy. The head sensor that monitors the movement of the operator is connected to the endoscope holder. The operator can thus move the endoscope smoothly from the operator’s point of view, and endoscope-user skill is not needed. A VATS lobectomy can be performed by only two operators （no scope user is needed）, and this is a major advantage of the new manipulator robot. We expect to see further advances in the use of robot assistance in surgeries.
