Electrogalvanic stimulation for levator syndrome: how effective is it in the long-term?
Academic Article
Overview
abstract
Levator syndrome is a symptom complex of severe pain and pressure in the anorectal area. Electrogalvanic stimulation (EGS) has been proposed as a treatment for this condition. Several reports have described EGS as up to 90 percent "effective" in treating levator syndrome, but the length of follow-up was uncertain or short-term in these studies. The purpose of this study was to examine the long-term benefits of EGS in levator syndrome patients treated at one institution. All patients undergoing EGS for levator syndrome between 1985 and 1991 were studied. Initial complaints, physical examination, number of treatments, procedure tolerance, and long-term benefit were determined through personal interviews and chart reviews. There were 52 patients (63 percent females and 37 percent males) with a median age of 54 years (range, 24-84 years). All patients presented with anorectal pain. Tenderness was localized by examination to the left in 43 percent, to the right in 23 percent, and bilateral in 8.6 percent and was not localized in 2.6 percent. Fifty percent received fewer than four one-hour treatments, 33 percent received four to six treatments, and 17 percent received more than six treatments. Seventy-seven percent felt that the treatment was painless. Follow-up results were as follow: number, 52; percent follow-up, 88; mean follow-up, 28 months (range, 0-71 months); symptoms relieved, 19 percent; partial relief, 24 percent; no relief, 57 percent. Of four patients with a wrong diagnosis, three were ultimately diagnosed with recurrent pelvic cancer and one had an anal fissure. At our institution, EGS was a tolerable treatment, but a substantial number of patients received no benefit. An organic etiology of anorectal pain must always be excluded.
