Chronic Anal Fissure Clinical Trial
Official title:
Randomized Clinical Trial of Transcutaneous Electrical Posterior Tibial Nerve Stimulation Versus Lateral Internal Sphincterotomy for Treatment of Chronic Anal Fissure.
Lateral internal sphinterotomy (LIS) is the gold standard against which all treatments are compared with a healing rate over 92%. However, the most serious complication of this procedure is anal incontinence. To overcome these problems, continued efforts are being tried to find less invasive treatments modalities for anal fissure that is as effective as surgical therapy with lower morbidity.
Sacral nerve stimulation has been recently tried for management of chronic anal fissure with
promising results. However, the technique described is invasive with the need for surgically
implantable expensive stimulator electrodes.
The aim of this study was to evaluate the efficacy of posterior tibial nerve stimulation
(PTN) by transcutaneous electrical nerve stimulation (TENS) and to compare it to the
conventional LIS. This non-invasive technique has been proved to be of acceptable results in
treatment of fecal incontinence and urinary incontinence.
