A prospective study of sexual function after major colorectal surgery

Area of Science:

• Urology
• Gastroenterology
• Neurology

Background:

• Pelvic autonomic nerves are crucial for sexual function.
• Rectal excision surgeries often risk damaging these nerves.
• Understanding nerve involvement is key to managing post-surgical sexual dysfunction.

Purpose of the Study:

• To review pelvic autonomic nervous system anatomy and function.
• To investigate the relationship between nerve tissue in surgical specimens and sexual function after rectal excision.
• To assess sexual outcomes in patients undergoing rectal surgery for cancer and ulcerative colitis.

Main Methods:

• Review of pelvic autonomic nervous system anatomy and function.
• Study of 32 patients undergoing rectal excision (28 for cancer, 4 for ulcerative colitis).
• Preoperative sexual history and neurological examination, examination of surgical specimens for nerve tissue, and 3-month postoperative sexual history.

Main Results:

• Ten sexually active men with rectal cancer showed impaired sexual activity correlated with excessive nerve tissue in specimens.
• Two of three women with rectal cancer reported satisfactory sexual function post-surgery.
• All four patients who underwent panproctocolectomy for ulcerative colitis maintained satisfactory sexual function.

Conclusions:

• Damage to pelvic autonomic nerves during rectal excision can lead to sexual dysfunction, particularly in men.
• Nerve preservation strategies during rectal surgery are important for maintaining sexual health.
• Patients with ulcerative colitis may have better sexual outcomes after panproctocolectomy compared to cancer patients undergoing rectal excision.
