PPH (is a minimally invasive surgery using anastomosis to treat circumferential prolapsed hemorrhoids), most of the postoperative bleeding is due to blood leakage from blood vessels of the surgical wound, dislodging of blood clot from the wound, and dislodging of ligature or hemostatic clip. 1. Bleeding from the surgical wound: most of the bleeding within 1 week after surgery is caused by bleeding from the surgical wound, and there is no effective means to prevent this complication. If the amount of bleeding is small, no special treatment is needed. If the patient is bleeding heavily, it is usually necessary to return to the operating room for suture ligation. 2. Blood clot detachment: Bleeding caused by blood clot detachment is usually seen from 7 to 16 days after surgery. Patients should avoid straining to defecate as much as possible after surgery to avoid dislodging the clot and causing heavy bleeding. 3. Ligation wire or hemostatic clip falling off: The ligation wire or hemostatic clip usually falls off around 7 days after the operation, which may lead to a small amount of bleeding and generally does not require special treatment, but if the bleeding is large, it may need to be re-ligated to stop bleeding. After PPH, patients are recommended to undergo regular checkups and seek prompt medical attention if discomfort occurs to avoid delaying their condition.
