Minimally invasive surgery for internal hemorrhoids mainly includes local injection of sclerosing agent, infrared coagulation therapy, collar ligation and hemorrhoid anastomosis surgery, all of which are relatively less invasive, and the recovery time after surgery depends on the area of surgery and the severity of the hemorrhoids, and the pain and discomfort after surgery. It takes about a month to return to normal. After surgery, try to keep the bowels open and develop good bowel habits to avoid dry stools, which will help the wound recover. Keeping the area around the anal opening clean also helps to promote wound recovery. Small local wounds can be cleaned and disinfected with iodophor and wound secretions can be wiped away to keep the wounds clean and dry, which is good for wound repair.
