It's easier than the original surgery. Usually shorter time in theatre and less days in hospital. As you have already had surgery you'll know more about pain management, walking around and all the other things that help you, plus the things to watch for when you go home. Depending on how much and what part was removed in the first surgery it may take a while to get used to your new "normal" bowel habits and sensations, but it's all manageable. I'm sure all will go well. Remember to pamper yourself a little, you've earned the right.
