The goal of anoplasty is to help regain normal function of the anus by widening the anal canal, thus helping stools pass more easily. If the patient suffers from anything else, like an anal fistula or imperforate anus, more surgery may be required. If an anoplasty has been recommended, it is likely due to anal stenosis or a narrowing of the anal canal. This condition is commonly caused by a hemorrhoidectomy or a congenital anal defect. The process may take place in one surgical procedure or may require multiple procedures, depending on severity. The surgeries take place under general anesthesia.
