AbstractObjective: Percutaneous tibial nerve stimulation is a recent and minimally invasive treatment for faecalincontinence (FI). The aim of this study is to evaluate the mid-term results in patients with idiopathic faecalincontinence (IFI).Methods: Fifty one patients (42 female and 9 male) were prospectively recruited. Patients were treated twice aweek for 6 weeks as per study protocol. We have assessed the degree of fecal incontinence using the ClevelandClinic faecal incontinence (CCF-FI) score at baseline, at 6 weeks, at 6 months and at 1 year. Also the anorectalmanometric data (mean resting pressure (MRP), squeeze pressure (SP) and, rectal sensation) at baseline, at 6weeks and at 6 months have been evaluated.Results: The median CCF-FI score was significantly decreased from an initial baseline value from 12 to 7 at 6weeks, 3 at 6 months and, 3 at 1 year (respectively: 1st interquartile 4.5, 1, 0 vs 10; 3rd interquartile 9, 5, 5 vs 14.5,p = 0.0001). Anorectal manometry showed an improvement of the internal (resting pressure, MRP) and the externalsphincters (squeeze pressure, SP) at 6 months compared to the baseline and 6 weeks by PTNS, while, RP and SPat 6 months was greater than at baseline and 6 weeks (p = 0.004 and p = 0.002 respectively).Conclusions: This study demonstrates that stimulation of the posterior tibial nerve could be an excellentprocedure for the treatment of IFI. The stimulation of the posterior tibial nerve can improve the fecal continence(CCF-FI score) in the short term and this improvement is maintained after 1 year of follow-up without treatment
