I had a radical abdominal trachelectomy last week and have just been discharged from hospital, so I'm afraid I can't give any assistance with fertility chances from a personal experience, which I suspect is what you're most eager to know about.
Do you know whether you are having the operation vaginally or abdominally? Because of the size and location of my tumour, I had to have the op abdominally. Your consultant will have his/her own views on fertility tailored to your circumstances, but if it helps, my consultant's view was that chances of conceiving are only slightly reduced if you have a vaginal trachelectomy. With abdominal trachelectomy chances of conceiving are vastly reduced although the statistics are too minimal to give any reliable indication.
If you are inclined to seek them out, there are some studies on trachelectomies that have been written up in medical papers. To be honest though I didn't really find these very useful as the outcomes seemed to vary so much from paper to paper.
In terms of recovery, I spent a week in hospital post-op. I'm not going to sugar coat it, it is a big op and I've been in a lot of pain, but the vast majority of the pain and immobility has come from the abdominal incision (muscles to cut through) rather than the op itself. My nurse also stressed that everyone is different and some people (e.g. me!) feel the pain worse than others.
I'm home now and getting better every day, the body is an amazing thing!
Hope your treatment goes well, feel free to get in touch.
