Not all hemorrhoids need to be dilated after surgery, but only if there is a narrowing of the anus after hemorrhoid surgery, which is usually most appropriate about 15-20 days after hemorrhoid surgery. Usually, if the recovery from hemorrhoid surgery is unsatisfactory, resulting in scar formation that can cause narrowing of the anus, which can adversely affect the patient’s bowel movements, then timely anal dilation treatment is required. The anal stenosis is found as soon as the hemorrhoid surgery is done, the anal area needs to be dilated immediately. Before the dilatation treatment, the area around the anus needs to be cleaned and anti-inflammatory through potassium permanganate lotion or saline, and the patient should be placed in a prone position with the buttocks elevated, and the area around the anus should be fully massaged. After the muscles and tissues around the anus are completely relaxed, the index finger with a finger sleeve is inserted into the anus and slowly moved to expand the anus.
