What is “total painless anorectal surgery”? The “Total Painless Anorectal Surgery” is a comprehensive reform of anorectal surgery from anesthesia, surgery and drug exchange, combining intraoperative sleep anesthesia, postoperative long-acting anesthesia and minimally invasive surgery, so that patients do not feel pain during the whole process from examination to surgery and postoperative healing, eat normally, do not control defecation, and basically do not affect life and work. The program has been carried out in our hospital and has been widely accepted by the public. After this project was carried out in our hospital, it has been well received by the majority of patients. What are the diseases for which “full painless anorectal surgery” is applicable? Hemorrhoids, anal fistula, anal fissure, prolapse, persistent constipation, perianal abscess, anal papilloma, anal eczema, anal acral warts, rectal prolapse, rectal mucosal prolapse, etc. When is the right time to have surgery if you have anorectal disease? In the past, because there was no “painless technology”, patients suffered from pain and surgery was even more painful, which made most patients suffer from pain for a long time because they were afraid of surgery, and when they finally had to operate, the anus was already seriously deformed, resulting in large surgical trauma, long healing time, and post-operative complications, which were very painful for patients. But now the “full painless anal surgery” has reached the maximum pain reduction to painless, patients can choose surgery as long as conservative treatment is not good, in order to prevent further deterioration of the disease, and early surgery is less traumatic, faster healing, more conducive to the recovery of anal function, so we recommend that early treatment of anorectal disease is better. The principle of our treatment is to remove all the anorectal diseases together in one treatment, for example, patients suffering from hemorrhoids, anal fistula and anal fissure at the same time, one treatment is the same treatment for all three diseases, not one treatment for one disease.
