Painless anorectal surgery is performed by means of intravenous general anesthesia, which puts the patient to sleep for an anastomotic suprahemorrhoidal mucosal cricothyrotomy. Painless anal surgery is also known as surgery to treat hemorrhoids and rectal mucosal prolapse. Prior to painless anorectal surgery, the patient is injected with anesthetic intravenously, and the patient will undergo the procedure without being aware of it. The process involves circumcision of the prolapsed hemorrhoid area, which consists of anastomosis of the mucosa and underlying tissue of the bowel wall at the lower end of the rectum, a treatment that facilitates excision of the affected area and reduces the blood supply to the hemorrhoid core. This painless surgery is suitable for patients who are afraid of pain, anterior rectal convexity, hemorrhoids enlargement, etc. The postoperative healing speed is faster, the impact on work and life is not great, basically one week to heal and leave the hospital. It is recommended that patients go to the hospital in time, surgical treatment needs to be carried out under the guidance of a professional doctor to avoid adverse consequences.
