The effect of biofeedback electrical stimulation for fecal incontinence is positive. Fecal incontinence is a functional gastrointestinal disorder in which abnormal fecal excretion pattern still exists after 4 weeks of age, and refers broadly to the loss of normal control at the lower exit of the digestive tract, which includes different connotations and different degrees, such as inability to control defecation during sleep, leakage of feces and inability to control dilute stools during gas, until complete inability to control gas and defecation. If one can control dry stool at will, but loses control of thin stool and gas, it becomes incomplete incontinence. If the anus loses the ability to control dry stool, loose stool and gas, and as a result, there is fecal mucus flowing out, contaminating the underwear and making the anus moist and itchy, then it is called complete incontinence. Normal bowel function requires a complete reflex mechanism, including the environment, the condition of the central nervous system, the sensory reflexes of the anorectal region, the integrity of the tension and sphincter muscles (myorectal ring) in the anal canal and the soundness of their innervated nerves. Any one of these components can be affected and cause fecal incontinence. The common clinical causes of fecal incontinence are: (1) neurological causes of incontinence. Including Alzheimer’s disease, cerebral arteriosclerosis, cerebral atrophy, cerebral embolism, traumatic brain injury, brain tumors, spinal cord tumors, etc. and peripheral neurogenic cauda equina neuritis and injury, anorectal and perineal nerve damage, etc. (2) Trauma to the perineum (including trauma from work, traffic accidents or war injuries). It can be a direct injury to the anal sphincter, or it can affect the contraction function of the anal sphincter due to the destruction of the adjacent tissues and scar formation, causing incontinence. (3) Anorectal diseases. Such as complex anal fistula, inflammation spreads widely, fistula branches, scarring is serious, etc. affect the function of the sphincter; rectal prolapse, anorectal inflammatory diseases and tumors involve the sphincter. (4) congenital anorectal malformations and fecal incontinence caused by complications after obstetrical and gynecological and anorectal surgery, of which anal fistula surgery and birth injuries are the majority. Regarding the treatment of fecal incontinence, there are several methods: drugs, anal incontinence control plugs, surgical treatment, biofeedback training and anal electrical stimulation. Among them, drug treatment is ineffective, only to dry the stool, slowing the role of the bowel discharge. Surgical treatment can be applied to severe cases, but it is not suitable for medium and light cases because of the large trauma. Biofeedback electrical stimulation is a recently developed rehabilitation tool that is widely used in the treatment of various pelvic floor muscle dysfunctional diseases. The principle is that the instrument monitors the biological signals of the perineal muscle groups and displays the signals in the form of sound or images, which are communicated to the treated person, and the patient understands the function of his or her muscles through the change of sound or images, and the patient controls the intensity and time of muscle contraction, and the signal changes accordingly; thus, the specific muscles can be consciously controlled according to the audio-visual signal cues to achieve the purpose of exercise. . Electrical stimulation functionally and structurally converts the fatigue-prone type II transverse muscles to type I, resulting in increased muscle fatigue resistance. The external anal sphincter and pelvic floor muscles are innervated by the sacral nerves from the sacral segment of the spinal cord (S2-4), and electrical stimulation directly activates the efferent motor fibers of the pubic nerves to increase anal sphincter pressure and stimulates the afferent sensory nerve fibers thus reflexively activating the motor nerves, which in turn act on the muscles to cause muscle contraction. Stimulation of sensory nerves improves the sensation of stool, increases rectal compliance, and regulates the local defecation reflex. Compared with traditional methods, biofeedback combined with electrical stimulation for the treatment of fecal incontinence has the advantages of positive effect, science, non-invasive and painless. Our hospital has successfully introduced the third generation of the most advanced international UROSTYM biofeedback electrostimulator and has been operating successfully, while also accepting adult patients for treatment. From the cases followed up so far, the clinical results are satisfactory.
