AIM: Percutaneous Tibial Nerve Stimulation (PTNS) is a minimally invasive treatment that can be performed in the outpatient clinic. This was a pilot study to investigate PTNS in the treatment of faecal incontinence.
METHOD: PTNS was performed by insertion of a needle-electrode near the posterior tibial nerve. Patients were treated twice a week. In cases with improvement in symptoms, maintenance treatment was started. Evaluation of faecal incontinence and quality of life was performed at baseline, 6 weeks, 3 months, 6 months and 1 year.
RESULTS: Twenty-two Patients were included in the study. The mean age was 60.4 ± 11.7 years. After 6 weeks, 18 patients continued in the study. Of these 13 had >50% decrease in incontinence episodes. Incontinence episodes decreased from 19.6 ± 21.0 at baseline to 9.9 ± 15.5 (P = 0.082) at 6 weeks and 3.6 ± 4.8 (P = 0.029) at 1 year. Incontinence scores decreased and postponement time increased both significantly during follow up. Significant improvement in quality of life was seen in most domain as measured by SF-36 and FlQL questionnaires. PTNS is a relatively simple method to treat patients with FI in an outpatient setting.
CONCLUSION: Good results of PTNS can be obtained and sustained during maintenance treatment.
