I had my surgery to remove my colon laproscopictally.
(is that a word?) lol.
But in the following weeks I had two surgeries and was cut open to untwist my bowel and one exploratory surgery for bleeding.
So when it came time two years later to remove my pouch (never worked right) I was cut open and given an end ileo.
But in saying that my last surgery was the easiest. I healed quickly and was back to work in six weeks.
I don't know if that helps any.
I think it may depend how long you have had your pouch and how much adhehion has occurred over time.
