Anal disease is a common disease, multi-morbidity, the ancients have long been “ten people nine hemorrhoids” said. According to statistics, the proportion of adults suffering from various anal diseases is as high as 70% or more. The most common type of anal disease is hemorrhoids, and there are different treatment methods, which is suitable for you? Laser therapy: clinical has been less applied – more complications, slow recovery of patients The commonly used CO2 laser for anal diseases, which can cut tissue and coagulate blood vessels, is commonly used to cut the skin, subcutaneous tissue, remove hypertrophic papillae or even external hemorrhoids, and coagulate to stop bleeding while cutting. Many hospitals in China have applied laser technology to treat hemorrhoids and achieved better treatment results. The United States, Russia, Austria and other countries have also reported more mature experience. The CO2 laser was used to treat hemorrhoids in the early 1990s, but was gradually phased out in the later years. The reasons for this are summarized as follows: i. Slow recovery. Since the laser is an injurious procedure, the incision healing time is longer than direct surgical excision, and there may also be perianal infection, hemorrhage, anal canal skin defect, anal stenosis, intractable anorectal pain, anal fissure and non-healing of the wound. Second, the laser is an instrument, and its control (such as laser dose, accurate positioning of surgery) is not as easy to master as surgery. Third, for deeper wounds, the laser cannot stop bleeding and secondary ligation is still required. Fourth, intraoperative cutting and spot cautery must be accurate, and the depth must be mastered, otherwise it is very easy to damage normal skin or muscle tissue, resulting in adverse consequences. Fifth, although the laser stops bleeding in a timely manner, it is easy to bleed when the scab falls off some time after surgery. Although laser therapy to remove hemorrhoids complications, but if the application of low power, telefocal irradiation physiotherapy, but will accelerate local blood circulation, enhance metabolism and tissue cell nutrition, for hemorrhoid inflammation, anal edge edema, slow healing of the wound will play a significant role in improving. Therefore, many hospitals are no longer using it to cut and stop bleeding, but to improve blood flow and promote metabolism. The actual hemorrhoids are a lot more than just the hemorrhoids. Although the injection method is effective, it has limitations and often needs to be combined with other surgical methods to cure hemorrhoids. In addition, injections are prone to recurrence after treatment. Also any injection, whether it is a sclerosing agent or a necrotizing agent, may cause complications such as anorectal stricture, anal swelling, and infected necrosis if there are deviations in the amount, concentration, and depth of the injected drug. Therefore, it is recommended that patients with hemorrhoids who are considering injectable treatment must find an experienced doctor. Ligation method: one of the best procedures – does not bring fecal incontinence The mechanism of ligation therapy is to block the blood supply to the base of the hemorrhoid nucleus by ligating it, so that the nucleus becomes anoxic and necrotic, the nucleus falls off and the base of the wound is repaired at the same time, and when the nucleus falls off the new granulation tissue quickly fills the wound to achieve healing. There are many ligation methods, which can be broadly divided into simple ligation method, ligature therapy, and external peeling and internal ligation method. If the doctor operates properly, the incision design is reasonable, and the ligation is moderate, ligation therapy is undoubtedly one of the best procedures for treating various kinds of hemorrhoids. The actual fact is that there are always some patients who are doubtful about this treatment, mainly for the following reasons: one, worry about causing fecal incontinence. From the anatomical point of view, external hemorrhoids are basically skin and mucous membrane elevation lesions at the junction of the anal canal and rectum, and do not involve the perianal sphincter muscle group. The ligature therapy will not cause damage to the perianal sphincter, so it will not cause fecal incontinence. Second, the fear of bleeding. If part of the external hemorrhoid is removed, the excised trauma will be exposed, and there may be a small amount of blood in the stool or dripping blood when defecating for a short period of time (usually 3~5 days), which is normal. As the wound grows and the granulation covers the wound, the bleeding will stop. Individual patients may also have a small amount of blood in the stool when the ligature is dislodged, but there is no need to worry as long as the amount is not too much. However, if there is still blood in the stool for a longer period of time after surgery, it should be a cause for concern. First, check whether there is anal spasm or stenosis, because either spasm or stenosis will cause lack of blood supply to the base of the wound, and the tissue will be relatively hypoxic, making it difficult for the wound to heal and resulting in constant blood in the stool. Secondly, if there is no spasm or stenosis, the trauma should be checked for proper drainage and, if necessary, the number of warm water baths and drug changes should be increased to facilitate rapid growth of the trauma. Those with slow trauma growth should also rule out the presence of vitamin deficiency, tuberculosis, diabetes, immunodeficiency, and other physical factors. If the trauma has completely healed and there are no bleeding lesions at the end of the rectum, but there is still blood in the stool every time you defecate, you should exclude the possibility of colorectal polyps and tumors, which patients should pay more attention to. Third, fear of anal stenosis. For a period of time after surgery, it is normal for the anus to feel constricted. As long as you keep your bowels open, take regular sitz baths and change medicine regularly, this feeling will gradually disappear when the wound surface heals and the anus gradually relaxes. However, if too much skin is removed (more than 2/3 of the perianal area) or too many internal hemorrhoids are ligated and the base is too wide and large, rectal stricture will inevitably occur after surgery, and the most intuitive manifestation of this is the thinning of the stool. However, even if stricture occurs, patients do not need to worry too much, as the majority of patients can recover through a period of sitz baths because of the abundant perianal blood flow. Even if the stenosis cannot be relieved, it will eventually return to normal after anal dilation treatment.
