Purpose: The "Total Mesorectal Excision" (TME) is the standard surgical technique for the treatment of rectal cancer. Up to 50% of sexual dysfunction is described after TME and up to 30% of urinary dysfunction. The main objective of the study is to compare pre- and post-TME sexual dysfunction according to the approach of the inferior mesenteric vessels, directly on the IMA or from the inferior mesenteric vein (IMV) to the IMA. Methods: Multicenter, prospective, controlled and randomized study of patients with rectal adenocarcinoma with neoadjuvant chemoradiotherapy, who will be randomized into two groups depending on the approach of the inferior mesenteric vessels. The main variable is pre and postoperative sexual dysfunction. The sample to be included will be 90 patients, 45 per group.
