Hi Adriana
If it helps my mum had this op in the UK about 10 years ago in her mid fifties. The success rate was low, from memory I think about 40% but the proposed benefit to her outweighed the risk (after an awful lot of thought and many years of pain) The surgeon waited for 2 years for technology to advance before he would do the operation, maybe because she was older, I'm unsure.
Her recovery time was long as well, particulary in hospital when nowadays you are made to get out of bed within 10 minutes. She had a special bed like the Thunderbirds chute which tipped up with her in it, so that she could walk off without having to bend to sit up for the first few times. Her grandkids thought it was brilliant!
After this she learnt to drive and had much more mobility, something which she could not have done pre op.
All the best to you for a swift recovery, which I'm sure will be helped by having your family around you too.
Take care.
