“An’s therapy” is a new method invented and innovated by Professor An A Yueh of Wangjing Hospital of the Chinese Academy of Traditional Chinese Medicine to treat a variety of anorectal diseases. This therapy is short, minimally invasive, less bleeding, less painful, shorter course of treatment, faster recovery and lower recurrence rate. After continuous development and innovation by Prof. An A Yueh, it has achieved very good efficacy in treating many kinds of anorectal diseases and has been recognized and praised by domestic and foreign colleagues. An’s therapy is at the leading level at home and abroad in the diagnosis and treatment of many diseases such as hemorrhoids, anal fistula, perianal abscess and rectal prolapse, especially in the research and treatment of annular mixed hemorrhoids, embedded hemorrhoids, high-grade perianal abscess, complex and high-grade anal fistula and rectal prolapse, which has made breakthrough progress. An’s injection method for hemorrhoids has made a qualitative breakthrough in efficacy and safety through the development of new drugs and improvement of injection methods compared with similar methods in the past. The “Paeoniflora Injection” (formerly known as An’s Hemorrhoid Solution) invented by Director An A Yueh is the only new Class II Chinese medicine approved by the state in the past decade for the treatment of hemorrhoids, which is suitable for different degrees of internal hemorrhoids and varicose mixed hemorrhoids, with a cure rate of over 95% in one injection, significantly higher than other injectable drugs. Necrosis, bleeding and rectal stenosis are the inevitable adverse reactions of the previous injection method, but Professor An A Yueh has created the “sixteen words secret” in the operation method, which completely simplifies the previous cumbersome injection method and makes it more flexible and clinically practical to standardize and scientificize the injection method, thus avoiding the above adverse reactions. The method of injection has been standardized and scientifically applied, thus avoiding the occurrence of these adverse reactions. It can be said to be a revolution and a sublimation of hemorrhoid injection therapy. An’s therapy for various complex high anal fistula and perianal abscess is another major feature. For a long time, the treatment of these two diseases has not been able to find a method that takes into account both the efficacy and the function of the anus, and the solution that is commonly used in China is “hanging thread”, but this method is painful, the course of treatment is long, the post-operative scar ditch is heavy, and at the same time, due to the blind creation of the internal opening, there is a high recurrence rate after surgery. “An’s therapy” adopts the unique method of finding the internal port and the non-wiring therapy of low incision and high hose drainage and the main focal incision and counter-oral drainage method to treat complex and high abscesses and anal fistulas, which can better protect the anal sphincter and the anal rectal ring and protect the appearance and function of the anus under the premise of ensuring cure. In the treatment of other difficult anorectal diseases, An’s therapy uses injection with minimally invasive surgery to treat cricoid mixed hemorrhoids and embedded hemorrhoids in a single thorough treatment while better solving postoperative anal skin defects, anal stenosis and other problems that have plagued the clinic for many years. The treatment of rectal prolapse by intra-rectal injection with ligation and anal tightening with Paeoniflora injection can solve the disease that was difficult to be cured by opening the abdomen in twenty minutes. The scope of application of injection therapy is expanded: from initial internal hemorrhoids to all stages of internal hemorrhoids and varicose veins type of mixed hemorrhoids. The efficacy is significantly improved: with one injection, the nucleus of hemorrhoid shrinks immediately and is cured in 3 to 5 days, with a cure rate of 98％. Safety is guaranteed: no local necrosis, no formation of hard nodes, no rectal stenosis, no bleeding. Minimally invasive surgery: Expanded scope of adaptation: Applicable to difficult diseases such as severe circumferential mixed hemorrhoids, complex anal fistula, rectal abscess, rectal prolapse, rectal polyps, etc. Significantly improved efficacy: 10 to 30 minutes treatment, 3 to 7 days cure, cure rate 99％. Safety is guaranteed: protection of the normal physiological structure and tissue of the anus, little damage, little pain, fast healing, no sequelae. The main contribution of An’s therapy is the development of the drug “Paeoniflora injection” which can replace surgery and is safe and less painful. The cure rate for all stages of internal hemorrhoids and varicose mixed hemorrhoids is up to 98%. “It is not only effective for hemorrhoids, but also has an obvious softening effect on anal hard knots and scars, and can be injected to treat anorectal stenosis after diluting the drug; at the same time, it can also treat anal itching and axillary odor by using the drug’s astringent and fixing effect and activating blood circulation. An’s therapy is applicable to severe circumferential mixed hemorrhoids. The innovation of this surgical treatment is that the external hemorrhoids are subconsciously peeled off with one small incision instead of the original large area, and the internal hemorrhoids are injected with the special anorectal medicine instead; the result of this treatment is that the normal physiological structure and tissues of the anus are protected while removing the hemorrhoids, and there is little postoperative pain, quick healing and no after-effects. Founder: Professor An A Yueh, Director of the Department of Anorectal Medicine, Wangjing Hospital, Chinese Academy of Traditional Chinese Medicine. An A Yue, male, Hui ethnicity. Member of the Democratic Progressive Movement, Director of the Department of Anorectal Medicine and An’s Therapy Center for Anorectal Diseases, Wangjing Hospital, Chinese Academy of Traditional Chinese Medicine. He is a chief physician, an expert of the Central Health Care Committee, a professor, a supervisor of doctoral students, a teacher of the succession of academic experience of old Chinese medicine experts, a member of the 11th and 12th National Committees of the Chinese People’s Political Consultative Conference, a member of the Standing Committee of the Chinese People’s Political Consultative Conference in Chaoyang District, Beijing, a member of the Science and Technology Medical and Health Committee of the Central Committee of the Democratic Progressive Party, and a special allowance of the State Council since 1993. She invented the “An’s Therapy” and the new national class II hemorrhoid drug “Paeoniae Injection” (formerly known as An’s Hemorrhoid Solution and An’s Hemorrhoid Injection), and has a personal non-functional invention patent. He has published more than 30 papers, such as “Clinical and experimental research on the treatment of hemorrhoids with Paeoniflora injection”, “Treatment of complex anal fistula by main focal incision and counter-oral drainage method”, “Discussion on the treatment of III rectal prolapse by scar fixation method of rectal injection and anal tightening operation “In 1991, he won the “Minister of Social Affairs Award” and the highest individual research award at the 40th World Invention Expo in Brussels. “In 1998, he was awarded the highest prize among all the medical exhibitors in China, and he was also appointed as a judge of the medical expert group of that year, and was listed in the 40th Eureka Who’s Who. In 1998, he was awarded as an advanced individual in national affairs. His invention “An’s Therapy” is a national continuing medical education program, which was approved by the Ministry of Health in 2004 as one of the “Ministry of Health’s Ten-Year Plan to Promote Appropriate Technology for Rural Areas and Grassroots Levels” and won the Second Prize of Science and Technology of the Chinese Academy of Traditional Chinese Medicine (first He is the first person to complete the project, at the ministerial level.) He has treated many national leaders and foreign friends, and has been reported by CCTV, Health News and other domestic and international media for many times. He has visited nearly 20 countries for lectures and surgical demonstrations. At present, he is in the leading position in treating various kinds of hemorrhoids, complex and high anal fistula, perianal abscess, rectal prolapse and other anorectal diseases in China, and has been called “the sage of hemorrhoids” and “An Yi Dao” by some media. Achievement: The most professional and authoritative method for treating anorectal diseases. He is the only one selected by the Ministry of Health to promote it nationwide; the Chinese Medical Association and the Chinese Society of Traditional Chinese Medicine have selected him as a national continuing medical education program; the highest science and technology award for the anorectal profession in the domestic Chinese medicine sector was given to him in 2004; ministers of health such as Qian Xinzhong, Cui Yueli and Chen Minzhang have given him inscriptions to encourage him; the method accepted and most trusted by many leaders; it has been clinically verified by tens of thousands of patients at home and abroad. Prospects for development: One of the many methods of treating hemorrhoids is called injection therapy, which is a method of injecting some drugs into the hemorrhoids through a syringe to make them shrink and fall off automatically to achieve the effect of treating hemorrhoids. The earliest invention of this injection therapy goes back more than a hundred years to England, when a doctor in Dublin used the injection method to treat a patient’s hemorrhoid area, not expecting an unexpected effect, and the patient miraculously recovered. Later this method slowly spread and our country also slowly began to try this treatment method. The advantages of this method are that it does not require surgery, and a gentle injection will cure the hemorrhoids. However, it also has the frightening disadvantage that it can lead to extensive cell necrosis and bleeding at the site of the injection, and because of this, the American medical community once removed this method from the books. Injections for hemorrhoid removal fell off the radar again until the advent of Antherapy. The Antherapy completely innovated the method of injecting drugs and injections, which not only broke the barriers to treatment of traditional injection therapy, but also solved the safety problems that could not be solved for nearly a century, and at the same time expanded the use of injection therapy, as long as the hemorrhoids, no matter how serious, can be effective with one injection, and there are no side effects and complications, and because of this it has received the medical community so many honors. Clinical verification: “An’s Therapy” was awarded three gold medals for world medical inventions in 1991, and was approved by the Ministry of Health in 2004 as one of the “Ministry of Health’s Ten-Year Plan to Promote Appropriate Technologies for Rural Areas and Grassroots Levels”, and is the only new technology selected by the Ministry of Health to be promoted nationwide. It is the only new technology for the treatment of anorectal diseases selected by the Ministry of Health for national promotion. It can be said that it represents the highest clinical level in the treatment of anorectal diseases in China at present. At present, it has been fully promoted in more than ten countries in the world and many provinces and cities in China. The “An’s therapy” is not “ancestral” or “secret recipe”, but a clinical research, improvement and improvement, after decades of clinical application in nearly 100 hospitals in China. It proves that “An’s therapy” is minimally invasive, less painful, faster healing, no sequelae, a high cure rate, safe treatment of anorectal diseases.
