The trauma can usually grow back in about 30 days after hemorrhoid ligation surgery. The threads of the ligation usually fall off about 10 days after surgery, and basically do not affect life for about 15 days after surgery, and the patient has no particularly severe pain. Nowadays, mixed hemorrhoids in hemorrhoid patients can be done with external peeling and internal ligation, where the external hemorrhoids are peeled directly and the internal hemorrhoids are ligated at the base, leaving the distal end of the internal hemorrhoids to lose nutrients and become ischemic and necrotic, which takes about 10 days. After necrosis it will fall off and the external hemorrhoid wound and internal hemorrhoid wound can grow completely, which takes about a month.
