When it comes to anorectal surgery, people naturally associate unbearable severe pain with surgery, so there is the saying that anorectal surgery is “the first pain in the world”, which is the main reason why many patients with anorectal disease who should receive timely surgical treatment are deterred by the “pain”. This is the main reason why many anorectal patients who should receive timely surgical treatment are deterred by the pain. The consequence of not receiving timely treatment due to fear of pain is that many patients are dragging out early diseases that are easily treated into advanced, complicated and difficult to treat situations. This not only increases the pain of patients, but also makes surgery more difficult for doctors and increases the complication rate. Our department now adopts the leading anorectal painless technology, which combines moderate sedation and conventional anesthesia to eliminate patients’ nervousness and fear during surgery and make anorectal surgery painless. The “new mode of anal anal analgesia and holistic care” and the professional medicine changer we have researched can make the incision painless, medicine change painless and bowel movement painless, so that the patients can complete the whole process of treatment and rehabilitation in a painless or basically painless state after surgery.
