Abstract

Aims: Even with the use of nerve-sparing techniques, there is a risk of bladder and sexual dysfunction after total mesorectal excision (TME). Laparoscopic TME is believed to improve this autonomic nerve dysfunction, but this is not demonstrated conclusively in the literature. In Indian patients generally, the stage at which the patients present is late and presumably the risk of autonomic nerve injury is more; however, there is no published data in this respect.

Materials and methods: This prospective study in male patients who underwent laparoscopic TME evaluated the bladder and sexual dysfunction using objective standardised scores, measuring residual urine and post-voided volume. The International Prostatic Symptom Score (IPSS) and International Index of Erectile Function score were used respectively to assess the bladder and sexual dysfunction preoperatively at 1, 3, 6 months and at 1 year.

Results: Mean age of the study group was 58 years. After laparoscopic TME in male patients, the moderate to severe bladder dysfunction (IPSS <8) is observed in 20.4% of patients at 3 months, and at mean follow-up of 9.2 months, it was seen only in 2.9%. There is more bladder and sexual dysfunction in low rectal tumours compared to mid-rectal tumours. At 3 months, 75% had sexual dysfunction, 55% at median follow-up of the group at 9.2 months.

Conclusion: After laparoscopic TME, bladder dysfunction is seen in one-fifth of the patients, which recovers in the next 6 months to 1 year. Sexual dysfunction is observed in 75% of patients immediately after TME which improves to 55% over 9.2 months.
