Mixed hemorrhoids external stripping and internal ligation usually do not need to remove the stitches, and the stitches will fall off naturally in 7~14 days. Mixed hemorrhoids refers to the internal hemorrhoids and external hemorrhoids in the same area above and below the dentate line are interconnected and fused together to form a whole vein mass across the dentate line, and the traditional procedure usually chosen is external stripping and internal ligation, the principle is to make the hemorrhoids fall off through ligation along with ischemia and necrosis of the threads, and thus usually do not need to remove the threads. External peeling and internal ligation is usually performed after anal dilatation, ligating the internal hemorrhoids 2~3 mm above the dentate line, because above the dentate line is innervated by autonomic nerves and has no obvious pain sensation, so the ligation is performed above the dentate line, so that the pain can be avoided; External hemorrhoids are removed under anesthesia using blunt stripping of external hemorrhoids to 3 mm above the dentate line and excision. External hemorrhoids are incised without sutures and these procedures usually do not require suture removal. If the patient external peeling and internal ligation surgery after any discomfort, timely to the hospital, have questions and doctors to communicate more, under the guidance of the doctor for targeted treatment.
