Ligation is a surgical procedure that involves ligating the diseased tissue to cut off the blood supply, thereby causing the tissue to become necrotic and fall off, and is less invasive than other treatments. Usually performed under endoscopic conditions, ligation surgery involves the use of an elastic rubber band to ligate diseased or hyperplastic tissues to cut off the blood supply to the diseased or hyperplastic tissues, thus accelerating the necrosis and detachment of the diseased or hyperplastic tissues. In clinical practice, ligation surgery is often used to treat ruptured bleeding esophageal varices caused by portal hypertension, hemorrhoid ligation, colon polyp ligation and so on. Transendoscopic esophageal variceal vein ligation is a commonly used method for controlling acute bleeding, which has the advantages of precise effect, simple and fast operation, and little injury. If the patient needs to perform ligation surgery, consult the relevant doctor’s opinion and consider it in the light of the patient’s condition.
