This article introduces the minimally invasive treatment of anorectal diseases (hemorrhoids, anal fistula, rectal prolapse), giving the general public a preliminary explanation of the minimally invasive treatment of anorectal medicine is the use of advanced instruments, combined with expert technology to achieve in small trauma and achieve the purpose of radical treatment. The main symptoms of hemorrhoids are bleeding, prolapse, pain and common anorectal disease, the incidence of 70%-80%, “folk have nine hemorrhoids”. Delayed treatment of hemorrhoids can produce harm and other diseases. Many patients also know that medication can only relieve symptoms and cannot cure them completely, yet they do not dare to have surgery, and the reason why they are afraid of surgery is because traditional surgical treatment of hemorrhoids makes patients suffer a lot, hospitalization and recovery time is long, complications are many, and recurrence rate is high; currently, minimally invasive surgery CRH and TST are carried out in China to cure hemorrhoids. The anastomosis is performed at the same time to lift the prolapsed anal cushion and restore the normal anatomical position of the anal cushion, which plays the role of “suspension”, while cutting off the arterial blood branches supplying the hemorrhoid nucleus, which plays the role of “disconnection”. “TST surgery has the following advantages: 1.Safety of surgery: no need to remove the anal cushion, maximum preservation of the normal function of the anus, avoiding complications such as anal stenosis and anal incontinence. 2.Surgery is painless: the hemorrhoid that has prolapsed from the anus is pulled back to its original position, while the blood vessels that provide blood to the hemorrhoid are truncated without damaging the perianal skin, so there is almost no pain after surgery. 3.Little surgical trauma and quick recovery: the anastomosis circumferential excision of mucosa is a non-open wound, less bleeding, eliminating the trouble of changing medicine after surgery, and you can resume normal life soon. 4.Surgery surgery time is short: the whole process only takes about half an hour. 5.Wide scope of surgical treatment: circumferential hemorrhoids, internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, circumferential hemorrhoids, embedded hemorrhoids, rectal mucosal prolapse, prolapse, etc. 6.Surgery is suitable for many people: because of less damage, it is especially suitable for middle-aged and elderly people, white-collar people who pay attention to efficiency and those who relapse from traditional treatment, and patients with mild prolapse and rectal mucosal prolapse. Therefore, TST has become a representative of the intergenerational revolution in the treatment of severe hemorrhoids with the advantages of safety, less pain, less bleeding, faster recovery, accelerated recovery cycle, and not affecting daily life. Anal fistula, also known as anorectal fistula, is an abnormal channel formed by a variety of pathological factors that connect the anorectal canal to the anal skin. It generally consists of a primary internal opening, a fistula, a branched canal and a secondary external opening. It can occur in both men and women, but is generally more common in young adults and more common in men than women. Surgery is the fundamental method to cure anal fistula. The principle of surgery is to reduce the damage to the anal sphincter to protect the function of the anus, and to completely remove the source of infection to cure the fistula. However, there are simple, complex, high and low anal fistulae, so the surgical treatment of anal fistulae is different, especially the treatment of high complex anal fistulae, which has been one of the difficulties in anal surgery. The most important thing is to make sure that you have a good understanding of the situation. In recent years, medical practitioners have made continuous improvements in surgical methods to preserve the function of the anal sphincter and puborectalis muscle, reduce the damage to normal tissues, and avoid sequelae. The common drawbacks of traditional fistula treatment such as fistula excision, fistulotomy, wire therapy, fistula open drainage, transanorectal mucosal flap endograft repair, etc. are large trauma, long healing time (6-8 weeks wound healing period), impaired anal function and even fecal incontinence in some patients. Currently, allogeneic decellularized allogeneic dermal matrix has been designed and used in China and abroad, and cut into anal fistula plugs for anal fistula filling treatment. The allogeneic decellularized allogeneic dermal matrix (ADM) is taken from human or animal skin tissues, and after special physical and chemical treatment, all components that may cause immune rejection after implantation are removed, while the three-dimensional scaffolding structure of the original tissues is retained intact, and as a cellular scaffold, it has the effect of inducing tissue generation, and can be recognized by human tissue cells as autologous tissue after implantation, and new blood vessels and After implantation, it can be recognized by human tissue cells as autologous tissue, and new blood vessels and fibroblasts will soon grow in, guiding the cells to grow along its collagen framework in an orderly manner, achieving the purpose of supplementing, repairing and even rebuilding tissue. The product is currently used for the surgical treatment of anal fistula and has achieved good clinical results. Compared with traditional anal fistula surgery, allogeneic decellularized allogeneic dermal matrix (ADM) anal fistula tamponade has the following advantages: 1. Good minimally invasive: this method is simple, easy to perform, small surgical blow, light postoperative pain, no rejection reaction and toxic side effects, and does not damage anal function or cause anal deformity. Its postoperative observation indexes are significantly better than those of traditional surgery; 2. Higher success rate: the success rate of this method is 80% or higher as of now; 3. Good safety, no rejection reaction, no toxic side effects; 4. The cost is not high, due to fast healing and recovery time saving 1 month than conventional surgery patients.
