ABSTRACT
AIM: In this study we reviewed our 10-year experience of the medium- to long-term success of sacral nerve stimulation (SNS) for faecal incontinence, with particular reference to the resource implications of running such a service. METHOD: All patients treated with permanent SNS implants for faecal incontinence from 2001 to 2012 were identified from a prospective database. The patients underwent follow up at 3 and 6 months, with annual review thereafter. They were divided into four groups: group 1, patients optimized after two reviews; group 2, patients optimized after further review; group 3, patients who failed to reach a satisfactory state; and group 4, patients who had a good initial result with subsequent failure. RESULTS: Eighty-five patients underwent permanent SNS with a median follow up of 24 (range: 3-108) months. Group 1 included 30 (35%) patients; group 2 included 27 (32%) patients [median of two (range: 2-6) additional visits]; group 3 included 18 (21%) patients [median of six (range: 3-10) additional visits]; and group 4 included 10 (12%) patients [median interval to failure was 54 (range: 24-84) months]. Twenty-seven per cent of our patients had an unsatisfactory outcome and the cost of follow up for these patients was £36,854 (48.7% of the total follow-up costs). CONCLUSION: The study highlights the significant resource implications of running an SNS service with a large proportion of patients requiring prolonged review, with more than one-quarter having an unsatisfactory outcome at a substantial cost.
