I had about 10 inces of my Sigmoid removed 7 years ago after having constant Diverticulitis. They were able to go in and remove the most diseased part of my sigmoid without a bag to wear afterwords. I was a very active 68 year old woman that was sick of being sick. For me, the surgery wasn't bad. I had a good colorectal surgeon that did it laprascopy. I never had alot of pain. I healed fairly fast and had to let my guts settle out and learn how to function without part of their sigmoid colon. My bowels were a little unpredictable but that settled out pretty fast. The surgery never made me nauseated or feel bad. Godbless Laprascopic surgery! You do have to be careful because you tend to forget that even though they didn't open you up, you have been through major surgery and need to take it slow for a while. If I had to, I would do the surgery again rather than risk a severe infection and perforation in the Diverticulum that results in a permanent bag after surgery. That's what happened to a friend of mine.
