oh, thanks Gingernut! Happy larry!
I have done some research and approx 1:60 bleed. Of those, 20% need further cauterisation under GA. [These people lose litres of blood!].
1:25000 die! (But due to complications, ie: old/frail.
There are 6 techniques for removing the buggers. Ranging from cold knife and pressure on blood vessels (mine), which supposedly reduces bleeding afterwards. Through diathermy / stitches/lasers and all the way to: no GA at all!
My surgeon had a patient a week before me who had to have them out without any anaesthetic due to her being obese (145kg). Too big to put under apparently. She did well he said

Lost 5kg so far and no number 2's for a week now on these drugs!!!!!!!!
