Computer Navigation-assisted Surgery for Locally Advanced and Recurrent Rectal Cancer

Computer navigation-assisted surgery has two main elements; the pre-procedural planning to create accurate 3D images of the pelvis allowing the surgical team to achieve an accurate perception of the operative field, and intraoperative navigation where these images are used for anatomical guidance to enhance surgical precision. Accordingly, computer software is used in this study to outline the tumour and other pelvic organs on pre-operative images which are subsequently used for intraoperative navigation.
