WHAT IS FECAL INCONTINENCE?
Fecal incontinence refers to the inability to control the passage of gas or feces. Its severity can range from incontinence of gas to liquid or solid feces. Unfortunately, it is a common disorder often not reported by patients due to the embarrassment associated with it.
WHAT ARE THE CAUSES OF FECAL INCONTINENCE?
There can be multiple, often concurrent, causes of fecal incontinence. One of the most common causes is damage to the anal sphincters that occurs during childbirth. Such injuries may be associated with varying degrees of damage to the nerves responsible for sensory and motor impulses to the sphincters. Postpartum injuries may not immediately result in incontinence, but symptoms can appear many years after childbirth. Other causes include sphincter injuries resulting from anal surgery, which may not lead to incontinence when the patient is young but can manifest later in life. Diarrhea can also contribute to fecal urgency, with liquid feces escaping through the anal sphincters, especially in cases of persistent diarrhea. It's important to note that fecal incontinence can also be the initial symptom of more serious conditions like chronic inflammatory bowel diseases (e.g., Crohn's disease, ulcerative colitis), rectal prolapse, or colorectal cancers.
HOW CAN THE CAUSES OF FECAL INCONTINENCE BE DETERMINED?
Taking a thorough medical history is the first step. In women, it's crucial to consider factors such as the number of pregnancies, birth weights of babies, and the use of forceps or vacuum extraction during childbirth, as these conditions can result in sphincter injuries. An initial coloproctological examination by a specialist may reveal sphincter damage, but for a more precise diagnosis, a transanal ultrasound is essential to detect the location and severity of sphincter injuries. Another significant diagnostic tool is anorectal manometry, involving the insertion of a small catheter connected to a computerized system into the anal canal. This test measures the resting pressure, pressure during straining, and the ability to maintain continence, allowing for an evaluation of sphincter functionality. Nerve function tests, such as pudendal nerve latency, can assess potential neurological damage.
WHAT CAN BE DONE TO CORRECT THE PROBLEM?
The treatment of fecal incontinence may involve dietary adjustments, the use of medications to firm up stool consistency, biofeedback (sphincter rehabilitation), surgical repair of sphincters, the implantation of anal pacemakers (sacral neuromodulation), or artificial sphincter placement. In cases of minor incontinence, specific dietary modifications or medications to control stool consistency may be sufficient. If fecal incontinence is related to inflammatory bowel diseases, treating the underlying condition is essential. Coloproctological specialists may recommend specific exercises to be performed at home, which can lead to positive results. Rehabilitation at specialized centers (biofeedback) is recommended for more severe cases and should always be attempted before any sphincter repair surgery.
Muscle injuries can be surgically repaired, with better results when the injury is recent and a postoperative rehabilitation period is followed. In cases of extensive sphincter damage or concurrent nerve injuries, artificial sphincters can be implanted to mechanically close the anal canal. These devices can be controlled manually by the patient when evacuating. However, the outcomes of these procedures are generally less encouraging. Another highly promising approach is sacral neuromodulation, in which a pacemaker, similar to a cardiac pacemaker, stimulates specific nerve roots originating from the sacral bone, which control the impulses to the anal sphincters. When feasible, this method can completely resolve the problem. In extreme cases where all other attempts have failed, creating a permanent colostomy may be necessary to improve the patient's quality of life.
