A haemorrhoidectomy is suitable for larger or external haemorrhoids. It is performed under general anaesthetic and involves excising the haemorrhoids from your lower rectum and anus. It is a very successful operation but patients often describe some pain post-operatively. This pain will be controlled with pain killers but it is likely you will need to take a week off work. Your colorectal specialist will be able to discuss in detail with you which procedure is most suitable for your haemorrhoids.
