The 2006 edition of the Hemorrhoid Clinical Diagnosis and Treatment Guidelines points out that asymptomatic hemorrhoids do not require treatment; the purpose of treatment is to eliminate and alleviate the symptoms; and relieving the symptoms is more meaningful than changing the size of the hemorrhoids. As people’s understanding of anorectal anatomy continues to improve, in-depth study of the mechanism of hemorrhoidal disease, the introduction of minimally invasive techniques and concepts as well as the application of modern high-tech, hemorrhoidal disease treatment is also constantly improving. At present, the treatment of hemorrhoidal disease, the general tendency is the combination of Chinese and Western medicine, non-surgical therapies and surgical therapies combined with minimally invasive and painless comprehensive treatment methods valued by doctors and patients. Minimally invasive medicine includes minimally invasive concepts and minimally invasive technology in two parts. The minimally invasive concept is carried out throughout the whole process of disease diagnosis and treatment; the minimally invasive technology implementation process is guided by the minimally invasive concept. Minimally invasive concept and minimally invasive technology requires “as little as possible or small trauma” so that the patient to pay as little as possible to achieve the same good results. The treatment of hemorrhoidal disease can be seen in the following kinds: 1, drug therapy drug therapy has internal and external drugs, used for bleeding hemorrhoids, hemorrhoids, thrombosed hemorrhoids pain, inflammatory hemorrhoids edema pain, etc., the drug therapy does not damage the muscle tissues, can alleviate the symptoms, is the first choice for mild hemorrhoidal disease, combined with a good diet, defecation habits and functional exercise can be avoided to avoid hemorrhoidal disease attacks and development. 2, injection therapy Injection therapy has long been a non-surgical treatment for internal hemorrhoids of degree I ~ II, the advantage is that the effect of the treatment of internal hemorrhoids can be comparable to surgery, less painful, short treatment time. Injection therapy can be divided into necrotic and withered method and sclerotic and atrophic method according to the effect of the injected drug on the tissue. This method of postoperative reaction is small, local scarring is less, usually in the submucosal layer injection, injection is too shallow or not much effect is not obvious, injection is too deep or the dose is too large, can cause serious complications. 3, physical therapy Physiotherapy treatment of hemorrhoidal disease, such as freezing, laser, infrared, copper ion electrochemistry, etc., mostly applicable to I ~ II stage of internal hemorrhoids, the operation method is simple, the treatment time is short, do not need hospitalization, popular with patients. Laser therapy surgery time is short, invasive, postoperative reaction light; wider indications, pregnancy, elderly patients or patients with other comorbidities are not suitable for traumatic surgery by laser treatment can achieve good therapeutic effect, part of the heart disease, hypertension patients can also be used in this procedure. However, after laser treatment, there are obvious edema, pain, bleeding during the shedding period, and some patients can not be successfully operated at one time and other shortcomings. Infrared coagulation can stop bleeding, but it is not as effective as injection therapy; cryotherapy has poor effect and postoperative pain, and is rarely used nowadays. Copper ion electrochemotherapy, through the electrode will copper ions into the internal hemorrhoid body, and the blood substances combined to form a copper complex, the complex in the tissue so that the microvascular blood flow slowed down, coagulation, vascular wall epithelial cell edema, aseptic inflammation, necrosis, mechanization, the hemorrhoids in the body of the reduction in the number of capillary blood vessels, the amount of bruising is reduced, hemorrhoids atrophy and become small, to achieve the therapeutic purpose. This method is the treatment of II degree internal hemorrhoid bleeding and prolapse simple and easy, but the efficacy of this method on external hemorrhoids is not exact. 4, ligation – ligation therapy ligation therapy is an ancient method of treating hemorrhoids, ligation method is the development on the basis of the traditional ligation, can be considered as the improved elastic ligation therapy. It is mainly applicable to the internal hemorrhoid portion of Stage I, II, III, IV internal hemorrhoids and mixed hemorrhoids. The treatment time of this therapy is relatively long, the patient suffers a lot of pain, and bleeding, pain, swelling, edema, infection, difficulty in urinating, anal stenosis, etc. are still among the complications. However, there are many improvements in the method at present. Ligation combined with stripping excision of external hemorrhoids – external stripping and internal ligation (Milligan Morgan’s procedure) is the mainstream procedure used by anorectal surgeons to treat mixed hemorrhoids, especially severe hemorrhoids, as well as mixed hemorrhoids accompanied by other anal diseases. With the application of minimally invasive concept and minimally invasive technology, anorectal clinicians have made a lot of efforts in anal cushion retention, dentate line retention, and retention of the skin bridge and the overall appearance of the anus plastic surgery, which can effectively protect the function of the anus and reduce the occurrence of postoperative complications after treatment. Long-term clinical practice has confirmed that external peeling and internal ligation has obvious and long-lasting therapeutic effects on improving clinical symptoms and signs. 5, anastomotic hemorrhoidal mucosal cricothyrotomy anastomotic hemorrhoidal mucosal cricothyrotomy (referred to as PPH) is a new technology for the treatment of hemorrhoidal disease developed in recent years with the rise of anal cushion displacement theory. This procedure is aimed at eliminating symptoms. The prolapsed anal cushion is reset through surgery and the structure of the anal cushion is preserved as much as possible during the operation, so as to achieve the goal of not affecting or as little as possible the ability of fine bowel control after the operation. The indications for the surgery are stage III and IV prolapsed internal hemorrhoids and circumferential mixed hemorrhoids mainly internal hemorrhoids, stage II and III hemorrhoids that have failed other surgeries; rectal mucosal prolapse. Compared with traditional surgery, the advantages of this surgery are: simple surgery, short operation time, less intraoperative bleeding; treatment of prolapsed circumferential internal hemorrhoids and hemorrhoids caused by bleeding effect is obvious; postoperative pain in the anus is light, short time, less long-term complications; postoperative hospitalization time is short, and the return to normal life and work early. The equipment used in this procedure is expensive, the long-term efficacy is uncertain, and there may be urinary retention, anal pain, anastomotic bleeding and stenosis, anorectal dysfunction such as urgency, postoperative infection, perforation and other complications and sequelae. Improper surgical operation technique is easy to recur after surgery. 6.Ultrasonic Doppler-guided hemorrhoidal artery ligation Hemorrhoidal artery ligation (DG HAL) is a simple, safe, painless, effective and less invasive treatment of internal hemorrhoids of degree II, III of the minimally invasive method, which is a set of ultrasonic investigation, ligation surgery as one of the new diagnostic and therapeutic techniques. Through the special rectoscope with ultrasonic probe to quickly determine the location of the hemorrhoidal artery, ligation of the hemorrhoidal artery, thus blocking the blood supply of hemorrhoids, reduce the internal pressure of the hemorrhoidal venous plexus, to achieve rapid hemostasis, hemorrhoidal atrophy, hemorrhagic hemorrhoidal disease, the efficacy of the treatment of hemorrhoids is very good. At the same time, the ligation effect can make the rectal mucosa and submucosal tissue adhesion fixed, to prevent the anal cushion downward movement, can also achieve the elimination of hemorrhoidal prolapse symptoms of the purpose. However, this procedure in the clinical use of time is still short, although the recent efficacy is satisfactory, but the postoperative period may also be complicated by anal tube submucosal hematoma, hemorrhoid tissue edema or thrombosed hemorrhoids, hemorrhage, pain, infection, and long-term efficacy is yet to be observed. There is now more publicity HCPT treatment, it uses high frequency capacitive electric field heat principle, the electrical energy is converted into thermal energy to make the treatment site tissue necrosis, dry knot, and then fall off, get the therapeutic effect. Applicable to some relatively simple anorectal diseases, such as one or two stages of internal hemorrhoids, isolated thrombosed hemorrhoids and inflammatory hemorrhoids, anal fissure, low simple anal fistula, perianal warts and so on. However, the treatment also has damage to human tissues and requires tissue repair process, which can lead to complications such as serious defects in the epithelium of the anal canal, narrowing of the anus or rectum, and infection of the wound. Later observation and treatment are required. Currently there is no hemorrhoid treatment method can be called an absolutely perfect hemorrhoid treatment method, each method has its own indications. In the entire diagnosis and treatment process of hemorrhoidal disease clinicians will be under the guidance of minimally invasive concept, follow the principle of individualized treatment, for different stages of hemorrhoidal disease comprehensive and reasonable choice of safe and effective and economical and simple minimally invasive treatment methods, reduce the patient’s pain, speed up the recovery time.
