Hi,
I had my rectum removed when I had my colon taken out due to UC in March '03. I was very lucky; though I was on steroids up until about a month prior to my operation, I still healed up incredibly well.
Sometimes, I don't know how to describe what I had done to others, so to put it bluntly, I had my backside sewn shut! Because I had recently been on steroids, they used the big, strong sutures to close me; I realize this has much to do with the patient's state of health as well as surgeon's preference (some surgeons use sutures underneath the skin that dissolve.)
The feeling was very different than what I was used to with UC; I did not feel sick at all, though the sutures were uncomfortable. My skin was pretty irritated, but when they took them out 2 weeks after the operation, I was good to go. This was all nearly 2 years ago, and I have been incredibly lucky- no problems since. I have been working full-time and have not encountered any physical limitation. I'd be lying if I said I was compeletly comfortable telling guys I date about this, but other than that, I'm very happy with the results of my operation and would do it over again if I had the choice.
Good luck
