Preoperative surgical planning based on cadaver simulation and 3D imaging for a retrorectal tumour: description and video demonstration
Retrorectal or presacral tumours include rare lesions growing into the retrorectal space. A recent systematic review with 82 patients found that these tumours are more frequent in women, mostly occurring around 40 years of age. In up to 95% of reported cases the mass was benign, schwannoma accounting for 33% of them .
Indications for surgery include compression of surrounding structures, symptoms, and features suspicious of malignancy or malignant transformation. According to tumour and patient features, different surgical approaches have been proposed. Minimally invasive surgery can be safely performed [1, 2], but no criteria have been agreed upon for selecting patients suitable for such an approach. It has been reported that there are no differences in the median size of the tumours between those removed by open vs minimally invasive surgery. However, solid or very large masses and a narrow pelvis could preclude minimally invasive approaches .
