Enema before hemorrhoid surgery is not very unpleasant, mainly the choice of soapy water or metronidazole sodium chloride injection for enema, which can have the effect of cleaning the intestines. Because hemorrhoid surgery is an anal surgery, if there is a large amount of feces in the anorectal area, it can easily interfere with the surgery and even uncontaminated wounds, leading to inflammatory infections later on. That’s why enemas are taken before surgery. After the enema the patient can go to the toilet and squat for 5-6 minutes, which can relieve the discomfort of distension. Hemorrhoids need to be treated with a change of medication after surgery, and at the same time to keep the bowels open and avoid dry, hard stools that can damage the wound.
