Aim: Faecal incontinence is frequent in the elderly. Little is currently known about the efficacy of sacral nerve modulation (SNM) in the elderly. The present study aimed to assess the impact of age on the outcome of SNM and on the surgical revision and explantation rates by comparing the results of a large data set of patients. Method: Prospectively collected data from patients who underwent an implant procedure between January 2010 and December 2015 in seven French centres were retrospectively evaluated. In total, 352 patients [321 women; median age (range): 63 (24–86) years] were included. Clinically favourable and unfavourable outcomes, and surgical revision and explantation rates, were compared according to the age of the patients. Results: A similar outcome was observed when comparing patients < 70 years and ≥ 70 years (a favourable outcome in 79.2% and 76.2%, respectively, P = 0.89). The probability of a successful treatment as a function of time was similar for the two age groups (< 70 years and ≥ 70 years, P = 0.54). The explantation and revision rates were not influenced by age (explantation rate: 17% in patients < 70 years vs 14% in patients ≥ 70 years, P = 0.89; and revision rate: 42% in patients < 70 years vs 40% in patients ≥ 70 years, P = 0.89). The probability of explantation as a function of time was similar for the two age groups (P = 0.82). The limitations of this study were its retrospective status, the rate of loss at follow‐up and different durations of patient follow‐up. Conclusions: Our results suggest that patients ≥ 70 years suffering from faecal incontinence benefit from SNM with a similar risk as a younger population. [ABSTRACT FROM AUTHOR]

Aim Sacral nerve stimulation (SNS) is effective for faecal incontinence (FI). Little is known about the relationship between the implantation technique and the functional outcome. This study aimed to explore the relationship between the numbers of active electrode poles (AEP) achieved during permanent lead placement and subsequent function, therapeutic amplitude and the need for extra appointments between scheduled follow-up visits. Method One hundred and eighty-six patients with FI who underwent permanent implantation between May 2009 and March 2015 with a tined (barbed) lead (3093/3080, Medtronic) using the straight stylet were registered on the European two-centre SNS prospective database (SNSPD). Correlation between the number of AEP, function, stimulation amplitude and the need for extra visits was analysed. Results The numbers of patients having an intra-operative motor response on stimulation of one, two, three and four poles were 18 (9.7%), 75 (40.3%), 61 (32.8%) and 32 (17.2%). The Wexner incontinence score was significantly reduced from 15 (±2.8) at baseline to 9.2 (±4.8) at the latest follow-up after a mean 878 ± 561 days (SD; P < 0.001). No correlation was found between the number of AEP and the functional outcome ( P > 0.05). Patients with four-AEP had a reduced therapeutic amplitude up to 289 (±146) days of follow-up ( P < 0.03). The number of AEP did not influence the need for extra follow-up visits ( P < 0.223). Conclusion The functional outcome and number of extra visits after SNS for FI did not depend on the number of AEP achieved. The therapeutic amplitude was reduced during the first postoperative year if four AEP were achieved during lead placement. [ABSTRACT FROM AUTHOR]

Aim The study assessed the initial experience with posterior tibial nerve stimulation ( PTNS) for faecal incontinence and compared it with sacral nerve stimulation ( SNS) performed in a single centre during the same timespan. Method A retrospective review of a prospectively collected database was conducted at the colorectal unit, University Hospital, Nantes, France, from May 2009 to December 2010. Seventy-eight patients diagnosed with chronic severe faecal incontinence underwent neurostimulation including PTNS in 21 and SNS in 57. The main outcome measures were faecal incontinence (Wexner score) and quality of life (Fecal Incontinence Quality of Life, FIQL) scores in a short-term follow-up. Results No significant differences were observed in patients' characteristics. Of 57 patients having SNS, 18 (32%) failed peripheral nerve evaluation and 39 (68%) received a permanent implant. Two (5%) developed a wound infection. No adverse effects were recorded in the PTNS group. There was no significant difference in the mean Wexner and FIQL scores between patients having PTNS and SNS at 6 ( P = 0.39 and 0.09) and 12 months ( P = 0.79 and 0.37). A 50% or more improvement in Wexner score was seen at 6 and 12 months in 47% and 30% of PTNS patients and in 50% and 58% of SNS patients with no significant difference between the groups. Conclusion Posterior tibial nerve stimulation is a valid method of treating faecal incontinence in the short term when conservative treatment has failed. It is easier, simpler, cheaper and less invasive than SNS with a similar short-term outcome. [ABSTRACT FROM AUTHOR]

Aim In the short term, implantation of a magnetic anal sphincter ( MAS) is a safe and effective treatment for faecal incontinence ( FI). In this paper we show that the initial results stand the test of time and patient satisfaction remains high in the medium term. Method Data on 23 women [median age 64 (35-78) years] implanted with a MAS device between December 2008 and September 2012 were reviewed from a prospective database. Assessment was based on significant improvement of incontinence scores - the Cleveland Clinic Florida Incontinence Severity ( CCF- IS) score, Faecal Incontinence Quality of Life ( FIQoL) score - and patient satisfaction at 6, 12, 24 and 36 months after surgery. Results The device was removed in two patients owing to complications. Median follow-up was 17.6 months. The median preoperative CCF- IS score was 15.2 and fell to 6.9, 7.7, 7.8 and 5.3 at 6, 12, 24 and 36 months, respectively. The median FIQoL score significantly ( P < 0.001) improved from 1.97 preoperatively to 3.19, 3.11, 2.92 and 2.93, respectively, at the same time periods. The concordance of the CCF- IS and FIQoL scores was 91%. Sixteen of the 23 patients were satisfied but only 14 would have recommended the MAS to someone else. Lack of improvement was the main reason for dissatisfaction. Conclusion Good initial results tend to remain stable over time and about two-thirds of patients are satisfied after MAS implantation.

Aim The magnetic anal sphincter (MAS) is a recent surgical innovation for severe faecal incontinence (FI). With its place in the treatment algorithm of FI yet to be defined, we report a nonrandomized comparison between MAS and sacral nerve stimulation (SNS) in a single-centre cohort of patients with FI. Method Data were reviewed from prospective databases. From December 2008 to December 2010, 12 women [median age 65 (42-76) years], having FI for a median of 6.5 years, were implanted with a MAS. Sixteen women, of similar age, preoperative function scores, aetiology and duration of incontinence, and implanted with a permanent SNS pulse generator during the same period, served as a reference group. The duration of hospital stay, complications, change in incontinence and quality of life scores and anal physiology were compared between the two groups. Results The duration of follow up was similar [MAS = 18 (8-30) months vs SNS = 22 (10-28) months; P = 0.318]. Four patients with MAS experienced a 30-day complication, and the device was removed from one patient in each group. A significant improvement in incontinence ( P < 0.001) and quality-of-life scores ( P < 0.04) occurred in both groups. Mean anal resting pressure increased significantly in patients implanted with a MAS ( P = 0.027). Conclusion In this single-centre nonrandomized cohort of FI patients, MAS was as effective as SNS in improving continence and quality of life, with similar morbidity. These results can now serve as a prelude to a randomized trial comparing the procedures. [ABSTRACT FROM AUTHOR]
