Abstract:
Introduction: The present systematic review and meta-analysis aims to investigate the role of Posterior Tibial Nerve Stimulation (PTNS) in the control of fecal incontinence (FI).
Methods: Two independent reviewers extensively searched in the electronic databases of Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, CINAHL, and Scopus for the studies published until the end of 2016. Only randomized clinical trials were included. The studied outcomes included FI episodes, FI score, resting pressure, squeezing pressure, and maximum tolerable pressure. The data were reported as Standardized Mean Differences (SMD) with 95% confidence interval.
Results: Five articles were included in the present study (249 patients under treatment with PTNS and 239 in the sham group). Analyses showed that PTNS led to a significant decrease in the number of FI episodes (SMD=-0.38; 95% CI: -0.67-0.10; P=0.009). Yet, it did not have an effect on FI score (SMD=0.13; 95% CI: -0.49-0.75; P=0.68), resting pressure (SMD=0.12; 95% CI: -0.14-0.37; P=0.67), squeezing pressure (SMD=-0.27; 95% CI: -1.03-0.50; P=0.50), and maximum tolerable pressure (SMD=-0.10; 95% CI: -0.40-0.24; P=0.52).
Conclusion: Based on the results, it seems that the prescription of PTNS alone cannot significantly improve FI.

● Posterior tibial nerve stimulation can lead to a significant decrease in the number of fecal incontinence episodes;
● Posterior tibial nerve stimulation have no effect on fecal incontinence score, resting pressure, squeezing pressure and maximum tolerable pressure;
● The prescription of posterior tibial nerve stimulation alone cannot significantly improve fecal incontinence.
Plain Language Summary
Fecal Incontinence (FI) is a common and important disorder that affects more than 10% of adults. Although the operation is considered an essential treatment strategy in managing and treating FI, recently, a systematic review has indicated that there is not enough evidence to support operation as a clinical treatment in adults. Therefore, alternative or adjunctive treatments may be needed. Posterior Tibial Nerve Stimulation (PTNS) is an option for treatment that recent studies have indicated its high effectiveness. PTNS is low-cost and easy to use without anesthesia; however, there is still an ongoing controversy regarding PTNS in FI treatment. In this regard, the present systematic review and meta-analysis aimed at reaching a general conclusion regarding the role of PTNS in the control of FI. For this purpose, we searched for related papers indexed in Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, CINAHL, and Scopus databases. Finally, 5 articles were included in the present study. Analyses showed that PTNS led to a significant decrease in the number of FI episodes, but it had no effect on FI score, resting pressure, squeezing pressure, and maximum tolerable pressure. based on these results, it seems that the prescription of PTNS alone cannot lead to a significant improvement in FI.
