AIM: Percutaneous tibial nerve stimulation (PTNS) has been shown to be an effective treatment in patients with urinary disorders; however its benefit in faecal incontinence is uncertain. This study aimed to assess the efficacy of PTNS in the treatment of urge faecal incontinence (UFI).
METHOD: A prospective study was conducted over a 14 month period assessing 31 patients with UFI treated with PTNS. The outcomes measured were: (1) reduction in FI episodes; (2) improvement in Cleveland Clinic and Vaizey incontinence scores; and (3) improvement in ability to defer defecation. All analysis was performed on an intention to treat basis.
RESULTS: Twenty one (68%) patients improved following PTNS and continue with the treatment protocol. Median Fl episodes per week reduced from 4 (range 0-30) to 0 (0-27), (P < 0.0001). Median Cleveland Clinic incontinence scores reduced from 13 (5-20) to 7 (0-20), (P < 0.0001). Vaizey incontinence scores decreased from 17 (5-23) to 10 (0-22), (P < 0.0001). Ability to defer defecation was improved significantly (P < 0.0001). No morbidity was encountered for any patient.
CONCLUSION: This preliminary study demonstrates that PTNS is an effective and well tolerated treatment for patients with UFI with particular improvement in reducing faecal urgency.
