Nerve-Sparing (NS) surgery is a technique which, in the last decades, has shown to be highly effective in order to significantly reduce intestinal, vesical and sexual dysfunctions without reducing surgical results in eradicating Deep Infiltrating Endometriosis (DIE). Following a correct and standardized anatomo-surgical approach, NS technique for DIE can be reproducible by the pelvic surgeon who desires to face surgery for DIE and can lead, for what is possible in severe cases, to an optimal preservation of the majority of the visceral nerve fibers of the pelvis. This approach has shown not to have a negative impact over recurrence rates, which are similar to those related to the classical technique, such as the rates of efficacy over chronic pelvic pain.
