There are many different surgical methods for hemorrhoids, such as injection therapy, traditional external peeling and internal ligation, PPH, CRH, copper ion therapy, hemorrhoid artery ligation under ultrasound Doppler, etc., all of which have their own advantages and characteristics. Although some of the newly developed surgical methods have more or less limitations or problems, it is undeniable that the current surgical treatment of hemorrhoids has evolved from the traditional rough and tumble style to the delicate and humane aspect. There have been many discussions and attempts by colleagues on how to reduce trauma, how to alleviate patient pain, how to avoid postoperative sequelae, and how to ensure long-term postoperative efficacy. Professor An Ahh, the inventor of An’s therapy, has made great achievements in injection therapy and improvement of the external peeling and internal ligature method, which has influenced and enlightened a large number of fellow anorectal surgeons. Indeed, just like what Prof. An Ahh did, in recent years, experts and scholars at home and abroad have put forward many new ideas, such as the anal cushion theory of hemorrhoids, etc.; at the same time, there are some new focuses and positive improvement initiatives in surgery, such as PPH and hemorrhoidal artery ligation, etc., which emphasize the treatment of the rectal mucosa in the painless area on the tooth line, but the unnecessary and excessive damage to normal tissues, sequelae and tedious surgery of such procedures are the major problems that anorectal surgeons cannot ignore. However, the unnecessary excessive damage to normal tissues, sequelae and cumbersome surgery caused by these procedures are something that the specialist can not ignore. Injectable therapy is a proven method of treating internal hemorrhoids, and Professor An Ahh invented and developed “Paeoniflora injection”. It is a new type of hemorrhoid injection, which is not only effective, but also abandons the side effects of traditional necrotizing agents and sclerosing agents, and avoids the occurrence of sequelae such as necrosis and bleeding and rectal stenosis. It can be said that Paeonia Bui injection therapy is one of the main core elements of An’s therapy, and the application of injection therapy has correspondingly promoted the improvement of mixed hemorrhoid surgery, which uses segmental dentate partial ligation combined with injection therapy, in which only a part of the prolapsed larger hemorrhoid nucleus is ligated, while the remaining part and other hemorrhoid nuclei are treated with Paeonia Bui injection therapy, and the combined procedure complements each other and works synergistically to significantly reduce the surgical trauma. Of course, with the continuous development of techniques and concepts of hemorrhoid surgery, we have a long way to go. Personally, I think that the various surgical methods have their own characteristics, so how to draw in the essence of each school of thought, each school of thought, to learn from each other, to make up for the shortcomings, this is the direction of research that our professional doctors should try. The change of concept in the middle of this is especially important, for mixed hemorrhoids, especially the annular prolapsed mixed hemorrhoids, the operator only focus on the nucleus of the hemorrhoid is not enough. To use an analogy, if the lining of a suit grows out of the cuff over time, we either have to cut off the lining and sew it at the cuff, or fold the lining inside the sleeve and sew it with a few stitches so that the prolapsed part can be pulled back. The prolapsed mixed hemorrhoid is like a prolapsed liner, it is not a problem of the prolapsed hemorrhoid itself, but a result of the relaxation of the rectal mucosa and the pathological downward movement of the anal cushion. The ligature of the rectal mucosa can be repositioned and the mucosal laxity improved by ligature suspension, which is like pulling the liner back from the inside. The doctrine of “lining” provides an image and guidance for the development and surgery of prolapsed mixed hemorrhoids, and the improvement of the corresponding surgical method draws on the principles and advantages of CRH, hemorrhoidal artery ligation, and PPH, and its improvement directly produces many positive effects: 1. There is no painful nerve, so the surgery focuses on the painless area of rectal mucosa, and the ligation and suspension treatment basically does not cause pain to the patient, thus reducing postoperative pain; 2. The number of wounds can be reduced by contracting the hemorrhoids to the anus, and some of them can be completely contracted without surgical excision. Even if there are residual external hemorrhoids, they are also significantly smaller than before the suspension, which significantly reduces the width of the incision when removing them; 5.Sometimes 4-6 incisions may be needed for the traditional surgery of circumferential mixed hemorrhoids, but only 2-3 incisions may be needed for the same case, and each incision is narrowed, which protects the normal skin more; 6.The number of anal margin incisions and The number of anal margin incisions and injuries are reduced, which better allows room for the preservation of the skin bridge and correspondingly reduces the chance of postoperative edema; 7. The humanized treatment is the direction we pursue, and we as professionals have the responsibility and obligation to continuously improve the surgical method, so that millions of people suffering from hemorrhoids dare to face and no longer talk about “hemorrhoids”.
