Outcome of Percutaneous Tibial Nerve Stimulation (PTNS) for Fecal Incontinence

Abstract

PTNS is a well-tolerated treatment with high acceptability in the majority of patients. It provides a sustained improvement in FI up to 42 months in a relatively noninvasive manner. The effect of PTNS diminishes with time and additional therapy sessions at 6 monthly intervals may result in greater improvements. PTNS ought to be considered as the first step in all patients with FI refractory to maximum conservative therapies.

The CONFIDeNT trial

“…1 The authors should certainly be congratulated for completing the study since surgical trials are notoriously difficult to implement but we would like to comment on its conclusions in view of our great experience administrating the therapy and treating such patients. 2,3 The authors conclude that PTNS did not confer any significant clinical benefit after 12 weeks because the primary outcome (i.e. 50% reduction in weekly incontinence episodes) was not found to be statistically different between PTNS (38% achieved the primary outcome) and sham (31%) patients.…”

Posterior Tibial Nerve Stimulation for the Treatment of Fecal Incontinence

“…These studies likely contained overlapping study populations and therefore may also contain duplicate results. 29,[33][34][35] …”

“…22 In 13 studies, subjects undergoing percutaneous PTNS had specifically failed conservative therapy for FI such as physical therapy with biofeedback, dietary modification, and antispasmodics. 10,21,[23][24][25][26][27][28][30][31][32]35,36 Four case series investigating percutaneous PTNS were published sequentially from the same institution, with a total of 334 subjects. These studies likely contained overlapping study populations and therefore may also contain duplicate results.…”
