Haemorrhoids, also known as piles, are enlarged, congested blood vessels, just under the surface of your anus (the opening of your bowel). Bleeding during bowel movements is the most common sign of haemorrhoids. Haemorrhoids can also cause pain and discomfort, especially when they protrude out of the anus, or if a blood clot forms inside a pile. To treat the larger, symptomatic haemorrhoids, your doctor may recommend one of the various surgical procedures available based on your symptoms. The surgical removal of symptomatic haemorrhoids is called a haemorrhoidectomy, and this can be performed using various methods, from cutting them off with an electric blade, to stapling or sealing them off with the various instruments available today. Discuss with your surgeon before deciding on the method best suited for your condition.
