Rectal cancer surgery can cause sexual dysfunction due to nerve damage. Advanced age and very low rectal resections significantly increase the risk of impotence and ejaculatory issues.

Area of Science:

  • Urology
  • Colorectal Surgery
  • Sexual Medicine

Background:

  • Major rectal operations, such as abdominoperineal resection (APR) and anterior resection (AR), can damage autonomic pelvic nerves.
  • This nerve damage frequently leads to sexual dysfunction in male patients post-surgery.

Purpose of the Study:

  • To investigate the incidence and factors associated with sexual dysfunction after major rectal surgery for cancer.
  • To analyze the impact of different surgical techniques (APR vs. AR) on sexual function.

Main Methods:

  • A study was conducted on 25 male patients under 60 with normal preoperative sexual activity.
  • Patients underwent either abdominoperineal resection or anterior resection (high, low, or very low).
  • Postoperative sexual function (potency, ejaculation) was assessed and compared between surgical groups.

Related Experiment Videos

Main Results:

  • Sexual dysfunction occurred in 66% after APR and 50% after AR.
  • Low and very low anterior resections showed high dysfunction rates (58% and 66%, respectively), comparable to APR.
  • Advanced patient age and very low resection level were identified as key factors contributing to sexual dysfunction.

Conclusions:

  • Sexual dysfunction is a significant complication of major rectal surgery for cancer.
  • While sympathetic nerve damage may be minimized with careful technique, parasympathetic damage is difficult to avoid.
  • Preserving the rectoprostatic fascia is crucial for preventing dysfunction in specific cases.
