Aim: Systemic sclerosis (SSc) is a multisystem disorder of unknown aetiology leading to the deposition of excessive connective tissue in the skin, blood vessels and internal organs. Gastrointestinal involvement occurs in 90% of cases and the prevalence of faecal incontinence (FI) is 38%. This study comprises the largest case series assessing the efficacy of sacral nerve stimulation (SNS) treatment for incontinence in this patient group.
Method: A retrospective analysis on prospectively collected data was performed on all SSc patients from our two centres who had undergone SNS for FI.
Results: Ten female patients of mean age of 54 (37-72) years had temporary SNS performed. The mean duration of FI was 13 (2-25) years. All had passive FI. Each patient had preprocedure anorectal physiology and endoanal ultrasound examinations documenting internal sphincter atrophy/fragmentation or reduced anal resting pressure. Overall there was no statistically significant difference (P = 0.57) in the total Wexner incontinence scores before (mean 15.1 ± 2.6 SD) and during temporary SNS procedures (mean 13.1 ± 3.6 SD). Two patients with a significant improvement went on to have permanent SNS with only one achieving a favourable outcome at 1 year.
Conclusion: This study showed that SNS failed to reduce episodes of leakage in nine out of 10 patients with systemic sclerosis affected with incontinence.
