For me I had a shower whilst in hospital on day 3, they had used a clear waterproof dressings over my incesions which seemed to do the trick. I was able to have a bath about 2 and a bit weeks after the op. I must admit when I first starting pooping again I was astonished at the colour and the awful smell, I have never before or since produced anything like it. Also for sore butt use whatever you use for a baby's nappy rash, I use Sudocrem and it works wonders.
