Introduction: Due to the absence of tactile sensation, it is difficult to recognize target structures that cannot be seen under laparoscopy. We are developing intraoperative navigation to obtain good orientation by applying preoperative images and real-time operation images. Here, we show our achievement of intraoperative navigation for laparoscopic hepatobiliary pancreatic surgery.
Methods: For preoperative simulation, an accurate 3D image is created from preoperative . In our department, in all cases of laparoscopic hepatectomy and pancreatectomy. For intraoperative navigation, the 3D image from preoperative CT is superposed on the actual surgical monitor of laparoscopic surgery in real time. The 3D images overlaid on the surgical image can be deformed according to the position of the camera and the movement of the targeted organ.
Results: By using the preoperative simulations, we can understand anatomical and positional relationships of each case preoperatively. Real-time intraoperative navigation can make it possible to recognize the positions of vessels and tumors difficult to observe from the surface.
Discussion: In laparoscopic surgery, by intervening in the monitor image, intraoperative navigation, that is difficult in open surgery, becomes possible. Because the positional error is not small, it is actually applied for surgical education for practitioners. As IT technology advances, intraoperative navigation will become a useful tool for improving endoscopic surgical techniques and surgical outcomes.
