Post-anal surgery mainly refers to hemorrhoids, anal fissures, perianal abscesses, post-anal impotence, and post-anal surgery patients may develop various complications such as bleeding, infection, edema, pain, delayed wound healing, and urinary retention. Food therapy can also prevent and reduce complications. (a) Dietary principles 1. Prevention and control of constipation In early postoperative constipation, dry stool irritates the wound surface, which not only aggravates pain but also may cause serious complications – hemorrhage, due to the fragility of the postoperative tissues, which are easily torn, and the ligature line is easy to slip under the action of external force. Therefore, it is important to prevent and control constipation for post-anal surgery patients, but we should also pay attention to not having diarrhea, and too many stools can also cause complications such as trauma infection, edema and bleeding. Diet regulation to keep the stool soft and formed, once a day is more ideal. Postoperative patients are advised to eat more fiber-rich vegetables and fruits, more gas-producing foods, more vitamin B-rich foods, and appropriate dried fruit foods containing more fat. Drink more water, eat more soup, porridge and other foods with high water content. 2, stop bleeding after hemorrhoid surgery trauma often partly open without stitches, a small amount of bleeding is normal, appropriate to eat some hemostatic effect of food can reduce symptoms. Such as shepherd’s purse, eggplant, lotus root, pork large intestine and vitamin C-rich vegetables and fruits. 3.Anti-inflammatory The trauma of hemorrhoids, anal fissures and anal impotence has feces passing through it every day, which is an infected trauma. If inflammation is not controlled, it will affect the healing of the trauma, so it is appropriate to eat foods that have a clearing and cooling effect on blood and anti-inflammatory effects, such as onions, capers, horsetail, garlic, mung beans, roots, toon, watermelon, bananas, bitter gourd, leeks, lettuce, celery, eggplant and other foods, as well as herbs such as chrysanthemum, acacia, and thin gong ying. 4, blood supplementation As the trauma of hemorrhoids is often open after surgery, the healing time is longer, and the bleeding time is also longer, usually around a month, or even longer. Therefore, supplementing some iron-rich foods can prevent and control iron deficiency anemia, and can also avoid the gastrointestinal side effects of supplemental drug iron and increase the absorption rate of the intestines. Such as amaranth, beef, spinach, black rice, mulberry, hairy vegetables, black fungus, kelp, sesame, pig liver, lard, rape, carrots, carp, etc., as well as traditional Chinese medicine such as Agaricus, Lingzhi, Cistanches. 5, blood activation, swelling, stasis, swelling and pain relief After hemorrhoid surgery, eat some foods that have the effect of activating blood and stasis, which can improve anal blood circulation, increase the blood supply to the trauma, enhance the anti-infection ability of the trauma, and speed up the healing of the trauma, such as cilantro, garlic, eggplant, lotus root, hairy beans, leek, rape, asparagus, kelp, pig’s blood, etc. After hemorrhoid surgery, due to the damage of surgery, so that the lymph and blood return flow is blocked, prone to edema, so you can eat some food that has the effect of reducing swelling and pain, such as pumpkin, celery, eggplant, green beans, mao beans, soybeans, garlic, rape, lettuce, loach, duck, olives, etc. 6, enhance nutrition, pay attention to the supplementation of gas after anal surgery patients in the diet stop to pay attention to nutrition. Because after experiencing surgical trauma, repairing the trauma needs protein, heat, vitamins and various trace elements. And from the perspective of traditional Chinese medicine, post-operative patients have varying degrees of qi deficiency, so they should eat more nutritious and comprehensive qi-supplementing foods, such as meat, eggs, poultry, aquatic products and yams, japonica rice, black fungus, red dates, broad beans, peaches, pumpkin, dried scallops and other foods, as well as traditional Chinese medicines such as astragalus, ginseng and atractylodes. 7, softening scars After hemorrhoid surgery there are more or less surgical scars, the elasticity of the scars is poor, the elasticity of the post-operative anus is bound to be poorer than the original, which can easily cause anal stenosis, medically induced anal fissures, etc. Therefore, consuming foods that soften scars as early as possible can assist in treatment. You can eat foods rich in antioxidants and vitamin E, such as soybeans, corn, onions, strawberries, and nuts such as peanuts, sesame, and walnuts. Eat more collagen-rich foods can also increase skin elasticity, such as pig’s feet, pig skin, pork bones, chicken claws, etc. 8, hemorrhoids after eating snapper, pigeon timing The first week after surgery is the period of inflammatory tissue fluid exudation, secretions exuded more, can produce tissue edema, at this time if you eat snapper, pigeon, fish and shrimp and other heterosexual high-protein food, inflammation can be radicalized, exudate more, edema is difficult to eliminate, so that the granulation proliferation is too fast, therefore should not eat. After a week to ten days, the wound tissue is in the stage of absorption and proliferation and repair, when eating snapper, pigeon and other foods can promote the growth of epithelial cells and accelerate the healing of the wound. But we should also pay attention to not eat too much, so as not to grow granulation tissue higher than the skin surface, but affect the wound healing. 9, after surgery to avoid alcohol and spicy food hemorrhoids after surgery patients should not drink alcohol and chili, ginger, mustard, curry, strong coffee and other foods, because these foods can aggravate constipation, aggravate the blood in the stool. (B) post-operative hemorrhoid sitz bath treatment is indispensable after hemorrhoid surgery patients defecate, feces often embedded in the wound, stimulating the wound, causing painful spasms of the anal sphincter, fecal residue on the wound, but also lead to inflammatory infection, affecting the healing of the wound. The anal sitz bath can clean the feces at the anus, release the anal sphincter spasm, promote perianal blood circulation, and speed up the wound healing. Therefore, post-operative hemorrhoid patients need to take a sitz bath with warm water for about ten minutes after each bowel movement. The sitz bath is followed by the necessary change of medication or the use of ointment or suppository treatment. (iii) Anal function exercise is also important for patients after hemorrhoid surgery The recurrence rate of hemorrhoids after surgery is high, and there are many reasons for recurrence, neglecting anal function exercise is also one of the important factors. After hemorrhoid surgery, the anal sphincter is mostly damaged to varying degrees. At this time, effective anal functional exercise can improve local blood circulation, reduce stasis and expansion of hemorrhoidal veins, enhance the contraction and diastolic capacity of the anal sphincter, increase the resistance of the anorectal area, and avoid and reduce the recurrence of hemorrhoids. For patients with incomplete anal incontinence, anal functional exercise is especially important.
