From your description you probably need surgery. It is a good thing that you have had your colonoscopy done. Stapled hemorrhoidectomy is as effective as open (classical) hemorrhoidectomy. Stapled hemorrhoidectomy is also less painful. Therefore I recommend the stapled procedure. Note that if any of your haemorrhoids is very large, or if you truly have a polyp, that particular pile may need to be removed separately. Thus you may end up having a stapled hemorrhoidectomy plus a partial classical procedure. Go to a surgeon who does stapled hemorrhoidectomies and take his advice.
