title: [Preoperative evaluation of laparoscopic surgery for colorectal cancer with a virtual three-dimensional multi-imaging].
abstract: Intraoperative palpation around the target organs and an overview of the operative field are difficult to achieve in laparoscopic surgery for colorectal cancer. Understanding the three-dimensional anatomy of the target organs and the neighboring structures along with a precise preoperative diagnosis is essential in individual cases for completion of an appropriate laparoscopic procedure. A routine virtual three-dimensional multi-imaging integrating PET/MDCT, CT colonography and CT angiography is useful for a precise diagnosis. Local anatomy and patient's features directly affect surgical outcome, especially in the laparoscopic surgery for the rectal cancer. CT pelvimetry is useful for a preoperative prediction of the difficulties of the laparoscopic surgery. These data should be taken into account when planning this procedure.
