Long-term outcomes of sacral nerve stimulation for faecal incontinence

Abstract

SNS remains an effective treatment for FI in the long term for approximately half of the patients starting therapy.

Outcomes of Sacral Neurostimulation Lead Reimplantation for Fecal Incontinence

“…explantations rates have been reported to vary from 10% to 24%, most commonly because of loss of efficacy. 13,14,19 Based on explantation rates in the literature, the causes for explantation in the current study are comparable with rates and indications reported previously in other studies. Reimplantation may be an option in these patients.…”

“…the remaining patients had replacement of the lead alone. in assessing the baseline characteristics of each group, the median CCf-fis was found to be significantly higher preoperatively in the reimplantation group as compared with the index implantation controls (index implantation: 17 (range, [8][9][10][11][12][13][14][15][16][17][18][19][20]; reimplantation: 19 (range, [12][13][14][15][16][17][18][19][20]; p = 0.002). in addition, the postoperative median CCf-fis was found to be significantly higher in the reimplantation group (index implantation: 7 (range, 0-20); reimplantation: 12 (range, 3-20) p = 0.028).…”

Sacral nerve stimulation for faecal incontinence: medium‐term follow‐up from a single institution

“…A common method defining success after SNS is a weekly reduction in frequency of major incontinence episodes by at least 50%. Using these criteria, the European SNS Outcome Study Group found long‐term success rates in 71.3% of patients, and full continence (no episodes of major incontinence) in 50.0% . However, using quantitative continence scoring systems, ‘full continence’ is regarded as St Mark's continence score of zero, which is uncommonly achieved with any procedure for faecal incontinence and we feel that quantitative scoring more accurately reflects the true definition of continence which includes involuntary soiling, urgency and flatus incontinence.…”

“…Sacral nerve stimulation (SNS) has redefined the treatment algorithm for faecal incontinence . One attraction of the procedure is the ability to do a temporary trial of nerve stimulation (peripheral nerve evaluation, PNE) to assess whether long‐term stimulation is likely to be successful, with 65–90% of PNE cases showing improvement and progressing to a permanent stimulator .…”

Long-Term Outcome Following Implanted Pulse Generator Change in Patients Treated With Sacral Nerve Modulation for Fecal Incontinence

“…Sacral nerve modulation has been shown to be effective for the treatment of severe FI when conservative measures have failed . It has become nowadays a standard treatment for this condition.…”
