A prospective crossover trial of direct current electrotherapy in symptomatic hemorrhoidal disease

Abstract

Many new modalities have been developed to treat symptomatic hemorrhoidal disease. In order to determine whether direct current electrotherapy therapy is effective, a prospective, crossover study was done. Sixteen patients referred for treatment of symptomatic hemorrhoids underwent a 16-week treatment protocol. Patients were randomized to receive either medical therapy with a sham therapy, or medical therapy with active direct current electrotherapy at 4-week intervals. All patients were instructed in medical therapy including sitz baths, hydrocortisone suppositories, topical preparations, and a high fiber diet with an educational booklet. Patients who did not respond to initial therapy were crossed over at 8 weeks, receiving alternate therapy twice. Improvement in symptoms, or lack thereof, was not statistically different between the two treatment groups. Comparisons of the internal sphincter pressure, external sphincter pressure, maximum squeeze pressure, and rectal sensitivity to balloon insufflation (volume) were not statistically different before, during, or after any treatment modality (p = 0.46, 0.60, 0.33). The size and grade of hemorrhoids on entry into the study had no bearing on the outcome. In a prospective crossover trial, no difference could be found between standard medical therapy and direct current electrotherapy in the treatment of symptomatic-hemorrhoidal disease.
