Aim:
Increasing life expectancy will increase the number of elderly patients with faecal incontinence. The study aimed to assess the safety and efficacy of sacral nerve stimulation (SNS) in patients over the age of 65 years.
Method:
Patients aged over 65 years, who underwent temporary SNS from 1996 for faecal incontinence unresponsive to conservative treatment, were followed prospectively.
Results:
Between January 1996 and December 2009, 30 patients [mean age 69.3 years (SD, 3.4)] underwent temporary SNS. Twenty-three (77%) had a >50% improvement in the St Mark's Continence Score and progressed to permanent SNS implantation. Their mean (±SD) score increased from 19 (3.2) at baseline to 8 (3.4) during temporary SNS and to 9 (3.4) 3 months after permanent SNS and 10 (3.7) at the latest median follow up (IQR) of 44 (20-150) months. The corresponding values at the same intervals for urgency [mean (±SD) min] were 1 (1.4), 8 (5.2), 8 (5) and 8 (5.4) and for incontinence episodes per 2 weeks [median (±IQR)] were 10 (7-14), 1 (0-5), 2 (0-5) and 0 (0-6).
Conclusion:
SNS is an effective treatment for faecal incontinence in patients over 65 years.
