PROSPECTIVE CONTROLLED AND RANDOMIZED STUDY OF THE GENITOURINARY FUNCTION AFTER RECTAL CANCER SURGERY IN RELATION TO THE DISSECTION OF THE INFERIOR MESENTERIC VESSELS
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.

Detailed Description
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. Although there are other factors, the main cause of postoperative genitourinary dysfunction is intraoperative injury of the autonomic pelvic nerves. One of the regions with more risk is the Inferior Mesenteric Artery (IMA). 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 secondary variables are visualization and preservation of the pelvic autonomic nerves, pre- and postoperative urinary dysfunction, pre and postoperative quality of life. The sample to be included will be 90 patients, 45 per group.

Intervention / Treatment |
---|---|
Experimental: Inferior mesenteric Vein dissection
To improve and preserve the rectal nerve in the total mesorectal excision, its starts the dissection from the inferior mesenteric vein to the inferior mesenteric artery and through the pelvis
|
Dissection of the Inferior mesenteric Vein first, and go down to the Artery during the total mesorectal excision
|
Active Comparator: Inferior mesenteric Artery dissection
As standard, the dissection starts straight in the inferior mesenteric artery and through the pelvis
|
Dissection of the Inferior mesenteric Artery directly in the total mesorectal excision
