In navigation surgery, preoperatively acquired image data are used so that surgical instruments can be guided inside the body while their location is displayed on a computer monitor. It is used in cranial nerve and spinal surgery. In the field of abdominal surgery, however, surgical manipulations in the target area cause major changes in the displayed images compared with those obtained preoperatively, and therefore, with the exception of certain organs, navigation surgery is difficult to apply. In general, this type of surgery aims to use intraoperative image information to improve surgical precision, carry out the preoperative plan accurately, and avoid dangerous areas. Three-dimensional images of the vascular architecture obtained with multislice computed tomography (MS-CT) make it possible to visualize arteries, the portal vein, bile duct, and even the pancreatic duct from any angle, which cannot be done with conventional angiography. Accurate positional relationships in the affected region can be determined preoperatively by manipulating multiplanar reconstruction images at a work station. MS-CT is extremely useful in navigation for safe performance of all types of pancreatectomy.
