AIM: This was a prospective study to evaluate the effectiveness of Posterior Tibial Nerve Stimulation (PTNS) for Idiopathic faecal Incontinence (FI).
METHOD: Eight patients with Idiopathic FI were included. They underwent PTNS over a 12 week period. Baseline Wexner scores and Quality of Life (QoL) scores were carried out prior to commencement of treatment and at 6 and 12 weeks after treatment.
RESULTS: Overall the Wexner Severity score improved over the 6 and 12 week period for all but one of the 8 patients by a mean of 4.4 points in 6 weeks and 5.8 by week 12 (P < 0.05). The reductions in score for incontinence to solid stool (2), liquids (1.5) and life style (1.625) were significant (P < 0.05) at 12 weeks. In the QoL score over time per patient and lifestyle factor significantly improved (P < 0.05) within 6 weeks of PTNS treatment and was maintained at 12 weeks. There were no significant changes to coping, embarrassment and depression in the QoL score.
CONCLUSION: PTNS showed significant reduction of Wexner Incontinence score and improvement in QoL over 12 weeks for Idiopathic FI. PTNS is a less invasive alternative to sacral nerve stimulation for this difficult condition.
