Functional and oncological outcome after multimodal treatment for rectal cancer could be improved. This can be achieved with a better recognition of anatomical dissection planes, of anatomical landmarks, and of the dissection margin to the tumor to optimize resection margins and to minimize iatrogenic nerve damage. Recently, the performance of stereotactic navigation for minimally invasive transanal rectal surgery has been reported. Additionally, critical challenges related to soft-tissue stereotactic pelvic navigation were assessed. Surgical navigation systems could improve the quality of surgery for rectal cancer as shown when used in other contexts. It is likely to improve the accuracy and efficiency of pelvic surgical procedures in which it is difficult or impossible to identify and dissect along anatomical planes.
