As the understanding of hemorrhoids becomes more adequate, the treatment of hemorrhoids is constantly improving. There are many different surgical methods for hemorrhoids today. In addition to the traditional surgery (external peel and tie), collar ligation, hemorrhoid anastomosis (PPH and TST) and hemorrhoid artery ligation and suspension are also widely used in clinical practice. However, both traditional surgery and minimally invasive surgery have certain advantages and disadvantages, such as obvious postoperative pain and long recovery time, while the anastomosis surgery can significantly reduce postoperative pain and other uncomfortable symptoms and shorten the recovery time, but it has a certain percentage of postoperative complications (such as stricture, bleeding or persistent anal swelling pain) and other problems. With the change in treatment philosophy, the treatment is no longer just about removing the hemorrhoid itself as it used to be, this is more evident abroad where only symptomatic hemorrhoids are treated as it makes more sense to remove the symptoms of the hemorrhoid than the hemorrhoid itself so that the patient’s main problem can be solved at minimal cost, which is the concept of minimally invasive. Laser hemorrhoid surgery is a relatively new procedure, but the procedure has been clinically used for more than 5 years in countries such as Europe and Africa, with an overall efficiency of about 90%, characterized by mild post-operative pain, short recovery time and high patient satisfaction, and its indications include the treatment of hemorrhoids of degrees II, III and IV. Our department is also the first to successfully carry out hemorrhoid laser surgery in the Shanghai area, and is one of the few hospitals in China to carry out this new technology. The mechanism is to destroy the blood supply to the hemorrhoidal vascular plexus by means of a special wavelength laser without removing the physiologically functional anal cushion tissue and anal canal skin, which is a non-invasive procedure that is safer and has no serious complications manifested compared to procedures such as anastomosis.
