Hemorrhoid ligation is performed by ligating a thick wire through the deep part of the hemorrhoid nucleus to make the nucleus ischemic and necrotic and fall off, and the wound will gradually heal on its own, this surgical method is simple to operate and the effect is practical and reliable. After the hemorrhoid ligation, the blood supply inside the hemorrhoid nucleus is blocked, and after the blood supply is blocked, the hemorrhoid nucleus will become ischemic, atrophy, and then necrosis, which will naturally fall off after necrosis, and the necrosis fall off period is about 7-10 days after the surgery. After surgery, patients need to take oral paraffin oil to ensure stool lubrication, sitz baths and antibiotics to prevent infection of the hemorrhoid nucleus, and there is very little secondary bleeding with this procedure because of the penetrating ligature when the hemorrhoid falls off.
