Conventional haemorrhoidectomy is the surgical removal of piles and is only used if you have severe piles and other treatments, eg banding and sclerotherapy, haven't worked. Conventional haemorrhoidectomy is done under general anaesthetic. This means you will be asleep during the operation. Your surgeon will cut the pile away from the muscle underneath and tie off the blood vessels to prevent bleeding. The exposed wound area will then heal naturally. Your surgeon may use stitches to close the wound.
