Radiofrequency Energy Transanal Treatment of Fecal Incontinence
Fecal incontinence is the involuntary leakage of stool from the rectum and anal canal. It is estimated that the disorder affects some 8% of the adult population. Medical management includes dietary measures, such as the addition of bulk producing agents to the diet and elimination of foods associated with diarrhea. Antidiarrheal drugs can be used for mild degrees of incontinence. Bowel management programs, commonly used in individuals with spinal cord injuries, may be effective in treating fecal incontinence.
Radiofrequency energy is being investigated as a treatment of fecal incontinence. This outpatient procedure utilizes conscious sedation and a local anesthetic. Radiofrequency energy is delivered to the sphincteric complex by an anoscopic device. The device (e.g., the Secca® System) has multiple needle electrodes that create thermal lesions deep into the mucosa of the anal canal. Over several months these lesions heal and the tissue contracts which is proposed to improve continence. Clinical trials to date have shown only a moderate effect that declines over time.
Radiofrequency energy transanal treatment of fecal incontinence is considered investigational.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy.

If there is a conflict between the Medical Policy and a health plan, the express terms of the health plan will govern.
Published data is inadequate to permit conclusions regarding the utilization of radiofrequency energy transanal treatment of fecal incontinence. Therefore this technology remains investigational.
