The term “hemorrhoids” often represents a general term for all anorectal diseases in the minds of the people, not just “hemorrhoids”. The incidence of anorectal disease is the most common human disease, the per capita incidence can reach 59.1%, the symptoms of mild anorectal disease can be treated with drugs, but the more serious must be surgery to cure, in the past, because there is no “painless technology”, the patient suffering from pain, surgery more painful, so that most patients are afraid of surgery, long-term suffering from the pain, very painful. It is very painful. Painless anorectal surgery is a comprehensive reform of anesthesia, surgery and drug exchange, combining long-acting anesthesia and minimally invasive surgery, so that patients do not feel pain during and after surgery, and can be treated as they go, which basically does not affect their lives, and patients can choose painless and minimally invasive surgery as long as conservative treatment is not effective, in order to prevent further deterioration of the disease, and early treatment wounds are tiny and recovery is faster. We suggest that early treatment of anal diseases is better. In addition, it is best for women who have not had children to have their hemorrhoids surgically removed before they are ready to become pregnant to prevent the triggering and aggravation of hemorrhoids during pregnancy. Painless anorectal surgery is suitable for common anorectal diseases such as hemorrhoids, anal fistula, anal fissure, prolapse, stubborn constipation, rectal protrusion, rectal mucosal prolapse, anal papilloma, anal eczema, anal acral warts, rectal polyps, etc. Patients with outpatient surgery can come and go with treatment, which is economical and cost-saving, and patients with medical insurance can enjoy medical insurance, inpatient treatment, fast in and fast out, and quick treatment and healing. The treatment of painless anorectal surgery also includes: “small surgery to cure stubborn constipation”, “PPH minimally invasive anorectal surgery”, “one-time cure program for a variety of anorectal diseases”. The “triple anti-recurrence therapy for anorectal warts” and “colitis consolidation and bacteriophageal promotion therapy” make patients completely exempt from the severe pain of traditional surgery and enjoy painless surgery with ease, which is the leading level in China and deeply praised by the majority of patients.
