There is no need to remove stitches after hemorrhoid surgery because the principle of hemorrhoid surgery is to ligate the excess internal as well as external hemorrhoids with a ligature. As the local tissue necrosis occurs, the ligature will fall off along with the necrotic tissue. After hemorrhoid surgery, there is no need to remove the ligature, and as the ligature falls off on its own, it also indicates that the local wound has healed. Therefore, the shedding of the ligature is also an important indication of whether or not the hemorrhoid surgery has passed the danger period. After the ligature wire falls off, it means that the local blood vessels of the wound in the anal area have been ligated and necrosed, and there is no blood supply, which excludes the possibility that the patient will have heavy bleeding from the wound after discharge. Therefore, the wound of hemorrhoid surgery only needs to be disinfected locally every day and does not need to be removed.
