1, must be maintained every day to solve the stool after surgery for anal diseases, because the patient is worried about the stool contamination of the surgical field, or because of the fear of pain and do not want to solve the stool, the result may occur in the anus above the rectum in the incarceration of the stool, at this time to be able to solve the stool is much harder, and even need to pick out with the fingers of the stool, the pain is much more serious. Therefore, patients must eat more vegetables, coarse grains, sesame oil, if necessary, oral pills, fruit guide and other laxatives to help solve the stool. 2, every day to change the medicine, to prevent close healing (pseudo healing) anal disease disease hemorrhoids fistula fissure postoperative wound recovery is attributed to: three points of surgery, seven points of the change of medicine. Wounds after surgery for anal diseases are highly susceptible to infection due to fecal stimulation, so conventional methods wounds are left open, wounds are healed by granulation tissue filling and skin crawling. Postoperative wounds of anal diseases include extra-anal wounds and intra-anal wounds, and intra-anal wounds and extra-anal wounds are connected together. If the wounds are not changed, the extra-anal wounds will heal in close proximity, also known as pseudo-healing. If the shallow wound is close together (pseudo-healing), the wound inside the anus is difficult to heal, resulting in medical anal fissure, anal pain and bleeding every time you relieve bowel movement. ② If the deeper wounds occur close together healing (pseudo healing), the anus will be collapsed, deformity, resulting in anal sphincter dysfunction. How to prevent wounds from healing together (pseudo-healing) after surgery for anal diseases? Change the medicine with a cotton swab to separate the wound and fill the wound with gauze, wait for the wound granulation tissue to grow up to fill the wound, and the skin on both sides of the wound to crawl to cover the wound trauma. 3, change the medicine after the relief of stool ① After the relief of stool, the application of soft towels and warm water to the anus at the stool gently wiped clean, to prevent the stimulation of stool on the wound, and then use the hairdryer to dry the anus. ② the patient placed in the left bending position (knees as close as possible to the abdomen), the patient’s right hand to the right side of the anus, the left hand of the drug changer will be the anus to the left side of the left side of the anus, the anus, in order to facilitate the change of drugs, and to reduce pain. (iii) the use of rehabilitation of new soaked gauze into the wound to change the medicine, anti-infection effect is better. In the rehabilitation of new soaked gauze plug into the wound before, can be used in the anal opening cotton swabs coated with Ma Yinglong hemorrhoid cream, lubrication, in order to facilitate the gauze plug into. Because of anal disease hemorrhoids fistula fissure postoperative wound recovery generally takes 2 weeks to 2 months, and some patients are not willing to stay in the hospital for a long time, so the families of such patients to learn to change the preparation, in fact, the method of changing the medication is relatively simple, it is easy to learn. During this period, the patient’s family members must accompany the patient to the hospital outpatient clinic once a week to review, and constantly get the doctor to point out, timely adjustment of the method of changing drugs. Another advantage of weekly outpatient review is that if the wound grows unsatisfactorily, it can be dealt with in a timely manner, such as granulation tissue grows too fast and needs to be cut, such as the occurrence of skin involution should be excised, so as to ensure that the wound grows healthily and satisfactorily.
