What is fecal incontinence? Fecal incontinence, also known as fecal incontinence, has not yet been fully defined and is mostly described symptomatically. It usually refers to the involuntary elimination of stool or gas through the anus at a socially unacceptable time and place after an individual has been toilet trained. How does the problem of fecal incontinence arise? 1. The ability to control bowel movements is related to many factors; 2. The ability of the rectum to retain feces: the ability of the nerves to send signals in a timely manner when the rectum is full. Fecal incontinence occurs when there is a problem with these functions. Fecal incontinence is a “big problem” Fecal incontinence often causes perianal skin ulcers, urethral and vaginal infections. Since bowel control is a basic survival skill that should be developed from an early age, fecal incontinence causes self-isolation, decreased autonomy, and feelings of aging and depression. It has also been reported that fecal incontinence, especially when combined with the presence of urinary incontinence, can cause sexual dysfunction, a decline in sexual relations and sexual life disorders. Most patients with symptoms of fecal incontinence, usually because it is difficult to talk about, do not pay attention to, or even think that “natural phenomenon of old age”, and reluctant to go to the hospital, which not only delays treatment, but also gradually derived into a serious impact on the quality of life of their own and their families “big problem “. Treatment methods of fecal incontinence: 1, conservative treatment: dietary fiber intake, drugs, biofeedback, bowel training, anal exercise. 2.Minimally invasive labor: sphincteroplasty, intestinal pacemaker (sacral neuromodulation) 3.Other surgical treatments: muscle graft sphincter reconstruction, artificial anus, biomaterial injection, paralleling enema method, colostomy. What is an intestinal pacemaker-interstim? It is a new neuromodulation treatment that uses weak electrical pulses to stimulate the sacral nerve near the caudal vertebrae, which serves to regulate the signal communication between the brain and the nerve, thus improving the corresponding symptoms in patients whose bowel movements have failed to respond to conventional treatment. Advantages of intestinal pacemaker therapy: 1. Minimally invasive (minor surgery) 2. Reversible (no destruction of human tissue) 3. Safe (safety officially approved by FDA, no serious life-threatening adverse events occur) 4. Can mediate parameters in vitro for long-term symptom control.
