Objective To assess therapeutic efficacy of sacral nerve stimulation (SNS) for patients with fecal incontinence (FI) without sphincter function defect.
Methods The screening stimulation of 2 weeks was performed in two FI patients without sphincter function defect. The defecation was recorded during the test, and it was effective when FI time reduce ≥ 50% in a week. Cleveland Clinic Florida fecal incontinence score (CCF-FIS) and FI quality of life score (FIQL) were evaluated.
Results At the end of screening, the FI times of 2 patients reduced more than 50%. Urgent defecation control time increased from < 1 min to 1-5 min. CCF-FIS score of 2 patients decreased from 15, 16 to 3, 3, respectively. FIQL scale also got a significant improvement. The stimulator was implanted in 2 patients.
Conclusions SNS is safe and effective in FI patients without sphincter defect in short term, and could improve the life quality of the patients.
