There is leakage of feces without tightening of the anal opening, i.e. anal incontinence. Its treatment is divided into non-surgical treatment and surgical treatment. 1. Non-surgical treatment Use antidiarrheal drugs to change the consistency and frequency of defecation, change dietary habits, use anti-motility performance agents. Biofeedback therapy: it can lower the rectal sensory threshold, increase the rectal volume, and reduce the frequency of defecation. Sacral nerve stimulation therapy: for functional defects caused by sphincter muscle atrophy, restoring sphincter function by stimulating the sacral nerve. 2. Surgical treatment: For severe anal incontinence where non-surgical treatments are not effective in improving symptoms, etiologic surgical treatments may be considered. Surgical options include: direct repair of sphincter defects, skeletal muscle transplantation, artificial sphincter implantation, colostomy and anterior colonic cleansing, and autologous fat injection. These are the basic treatments for anal incontinence. It is recommended that after the diagnosis is clear, the patient should choose the appropriate treatment plan according to the individual’s specific condition and under the guidance of the doctor’s evaluation.
