Fecal incontinence refers to the involuntary loss of gas or liquid stool (called minor incontinence) or the involuntary loss of solid stool (called major incontinence). Continence requires the normal function of both the lower digestive tract and the nervous system. The anal sphincters, along with the pelvic muscles that surround the end of the digestive tract, ensure controlled movement of digestive tract contents. There are many possible causes of fecal incontinence; in most cases, incontinence results from some combination of damage to the anal sphincters, neurologic causes, decreased distensibility of the rectum, fecal impaction and diarrhea. Treatment includes behavior changes, medication, the use of bulking substances, treatment of impaction, nerve stimulation and surgery.


Bulking Agents

Several agents (Durasphere, silicone biomaterial, etc) have been studied for the treatment of fecal incontinence. To date, only one bulking agent has been approved by the FDA for treating fecal incontinence. This is a formulation of non-animal stabilized hyaluronic acid/dextranomer in stabilized hyaluronic acid (NASHA Dx) and is marketed by Q-Med as Solesta. Solesta is a sterile gel that is injected into the anal canal. It is composed of naturally made materials, dextranomer and sodium hyaluronate. Solesta is classified as a medical device (injectable bulking agent) and not a drug.


Transanal Radiofrequency Therapy

Radiofrequency (RF) energy has been investigated as a minimally invasive treatment of fecal incontinence, a procedure referred to as the Secca procedure. In this outpatient procedure using conscious sedation, RF energy is delivered to the sphincteric complex of the anal canal to create discrete thermal lesions. Over several months, these lesions heal and the tissue contracts, changing the tone of the tissue.


Perianal Electrical Nerve Stimulation

Electrical stimulation with a non-implantable stimulator is delivered generally by anal probes connected to an external pulse generator. The electrical stimulation is controlled via a probe wired to a device. A variation in the amplitude and frequency of the electrical pulse is used to mimic and stimulate the different physiologic mechanisms of the voiding response, depending on the type of etiology of incontinence. The Urgent PC Neuromodulation System is not FDA-cleared for the treatment of fecal incontinence. The company’s website states that the treatment can be used for this condition and that the recommended initial course of treatment includes 12 weekly sessions. In February 2014, the InTone®MV (InControl Medical, Brookfield, WI), a nonimplantable device that provides electrical stimulation and/or biofeedback via manometry, was cleared by FDA. The device is intended for the treatment of geno typical male and geno typical female urinary and fecal incontinence.


Posterior tibial nerve stimulation (PTNS)

The procedure for PTNS consists of the insertion of a needle above the medial malleolus into the posterior tibial nerve followed by the application of low voltage (10mA, 1–10 Hz frequency) electrical stimulation that produces sensory and motor responses (i.e., a tickling sensation and plantar flexion or fanning of all toes). Noninvasive PTNS has also been delivered with surface electrodes.


Vaginal Insert for Bowel Control

The Eclipse™ Vaginal Insert system (Pelvalon, Inc.) is an inflatable vaginal insert designed to exert pressure on the rectal vault to treat fecal incontinence. According to the manufacturer, the Eclipse™ system consists of a vaginal insert and a pressure-regulated pump. The insert, consisting of a silicone-covered stainless steel base and a posteriorly directed balloon, is placed in the vaginal vault and inflated. The balloon is deflated via the pump when the user needs to have a bowel movement.


At Home Voice Guided Exercise Program

InToneMV provides a 12 minute voice-guided therapy session, completed in the of the members home. The session instructs the member to complete both short (3 second) and long (10 second) voluntary contractions. The lighted visual biofeedback graph encourages slow contractions, maintain the lights then release at end of contraction timer. The variation ensures both fast and slow twitch muscle fibers are recruited.


Anal Sling

Anal sling is a mesh implant with minimally invasive delivery, to provide support to the anorectum and reduce the incidence of fecal incontinence episodes in women. For example the TOPAS system is comprised of a knitted, Type 1 polypropylene monofilament mesh, which is covered by removable insertion sheaths, and two insertion needles. Implantation is through a transobturator approach via two small incisions in both the thighs and buttocks, requiring about 30 minutes for implantation and a short period for recovery. The implanted mesh is self-fixating and permanent with tissue in-growth providing additional anatomical support to the anorectum. Surgical placement of a perianal sling designed to enhance the anorectal angle may be a potential option for patients, but additional studies are needed.


Magnetic Anal Sphincter

The device, known as the Fenix® Continence Restoration System is comprised of an annular series of connected titanium beads. Each bead contains a magnetic core which is magnetically attracted to adjacent beads. Collectively, this attraction augments the native anal sphincter providing needed resistance to involuntary opening of the anal canal. The Fenix implant is supplied sterile and placed through a perineal incision. The available studies on use of the magnetic anal sphincter includes studies that found surgical implantation resulted in a reduction of fecal incontinence in some individuals. Studies also revealed that implantation has been associated with complications including but not limited to infection, erosion of the device, injury during the surgical procedure, pain, constipation and incontinence.


Practice Gudielines and Position Statements

National Institute for Health and Clinical Excellence

National Institute for Health and Clinical Excellence concluded "Current evidence on the safety and efficacy of injectable bulking agents for fecal incontinence does not appear adequate for this procedure to be used without special arrangements for consent and for audit or research, which should take place in the context of a clinical trial or formal audit protocol that includes information on well-defined patient groups."


Note: See the related policy, Anorectal Biofeedback number 02.01.04.


The Agency for Healthcare Research and Quality (AHRQ) published a systematic review on treatments for fecal incontinence. The authors found a lack of comparative studies on Secca and concluded that the evidence for the procedure was insufficient.


American College of Gastroenterology

The American College of Gastroenterology (ACG) published guidelines on the management of benign anorectal disorders in 2014. The guideline indicated that there is insufficient evidence to recommend radiofrequency ablation to the anal sphincter as treatment for fecal incontinence. ACG also asserted that the biological rationale for this type of treatment is unproven.


Prior Approval:

Not applicable.



Refer to policy 02.01.04 for information regarding Biofeedback for fecal incontinence.

Refer to policy 08.01.21 for information regarding Sacral Stimulation for fecal incontinence.

  1. Transanal radiofrequency therapy for the treatment of fecal incontinence (also known as the Secca procedure) is considered investigational because its effectiveness has not been established.
  2. Perianal electrical stimulation is considered investigational because its effectiveness has not been established.
  3. The use of injectable bulking agents (Solesta, autologous myoblast cells, collagen, etc) for the treatment of fecal incontinence is considered investigational because their effectiveness has not been established.
  4. Posterior tibial nerve stimulation for fecal incontinence is considered not medically necessary.
  5. The use of the vaginal bowel control vaginal insert, electrical continence aids (i.e Eclipse) are considered investigational.
  6. The use of bowel control anal insert (e.g. Renew Anal Insert) is considered investigational.
  7. At home treatment/exercise programs for fecal incontinence (i.e InToneMV) are considered investigational.
  8. Injection of mesenchymal stem cells/autologous cell therapy for fecal incontinence treatment is considered investigational.
  9. The use of a magnetic anal sphincter (eg, Fenix Continence Restoration System) is considered investigational
  10. Surgical placement of an anal or pubo-rectal sling (i.e. TOPAS™ treatment) is considered investigational. 


The above treatments for fecal incontinence lack demonstration of efficacy and long term effects at this time. There remains a lack of information regarding the predictive factors for successful treatment selection at this time.
