One-year follow-up study on the effects of electrogalvanic stimulation in chronic idiopathic constipation with pelvic floor dyssynergia.

BACKGROUND: Constipation is a commonly reported symptom, and pelvic floor dyssynergia is frequently documented in constipated patients. The standard therapeutic approach for pelvic floor dyssynergia is biofeedback training, but long-term studies show that a significant percentage of patients remain symptomatic. Alternative or adjunctive therapeutic options are needed. AIMS: The purpose of this study was to evaluate the long-term effects of electrogalvanic stimulation in patients with pelvic floor dyssynergia and severe constipation, to see whether this treatment may be of some benefit. PATIENTS AND METHODS: Thirty consecutive constipated patients with clinical and instrumental evidence of pelvic floor dyssynergia entered the study and were treated with a standard high-frequency galvanic electrostimulation protocol. Clinical and instrumental (colon transit time, anorectal manometry, defecography, rectal balloon expulsion) assessment evaluations were performed basally and one year after the treatment.
RESULTS: Overall, approximately 50 percent of patients showed significant improvement after electrogalvanic treatment, from both a clinical and an instrumental point of view, as shown by the objective measurements obtained through manometry, defecography, and the balloon expulsion test. The benefit was limited to normal transit constipation patients.
CONCLUSIONS: Because of the relatively simple, painless and effective nature of electrogalvanic stimulation, we concluded that it may represent a useful adjunct to the therapeutic armamentarium for pelvic floor dyssynergia in normal transit constipation.
