Anal muscle laxity, which should be referred to as anal sphincter laxity, can be operated. However, it is recommended to do anal lifting exercises or physical therapy first, according to the strength of the pelvic floor muscles to improve the situation. If the situation still cannot be improved after a period of time by doing the anal lifting exercises or physical therapy, then anal reduction surgery can be considered. The goal of anal retraction is to increase the tension in the external anal sphincter and to reinforce the results of the rectal prolapse surgery. The procedure is performed in the lithotomy position, with a semicircular incision made at the posterior anal verge, separated to the plane of the dentate line, making the semicircular incision longitudinal, then removing excess skin and suturing the muscle, mucosa and skin, with the sutures being tightened to a width of roughly two fingers. The postoperative effect of anal sphincter surgery is better, can reduce the anal incontinence caused by anal sphincter relaxation, but the repair period is longer, and the pain is obvious, good care, and need to comply with the doctor’s instructions.
