I had the Lletz procedure to treat CIN 3 under general anesthetic three days ago, so thought I could share some experience details!
I think situations vary from person to person and also the area you live in but the way the NHS do it in my area was to first carry out a pre-op over the phone with you about a week or two before you go in. Its just a load of questions about your health and related symptoms etc.
My appointment was first thing in the morning at 7am. There were four other women there for the morning slot too. The surgeon came round to talk us individualy and then the anethetist. The nurses came round to you one at a time too. Just to take blood pressure and things like that. By 9am the first person goes upstairs with the nurse, I was fourth on the list.
So you are taken to the room upstairs to be prep'd for surgery, the anethetist and nurses are there and they were lovely,.. saying to 'think about the beach' while they are administering the anesthetic (this was great because upon waking you feel like you had an amazing dream about the beach! And you wake feeling really relaxed and happy) Before you know it you are awake and with nurses on the recovery ward, talking about all kinds of silly things u said whilst still coming round properly. You are here briefly before being taken back downstairs to your ward (still on the bed)
A nurse comes over to check the pad inbetween your legs and you are also offered tea and toast. By this time it was around midday (I dont think I was upstairs for very long at all really prob an hour for prep, surgery and recovery all in all) I didnt have any pain after, but if you do you get offered tramadol for pain relief. I also found that the effects of the anesthetic afterwards, took away all my worries that I had before hand and made me very chatty which was lovely.
Then its just a matter of waiting to be discharged by a nurse. She tells you all the dos and donts for the next 24 hrs and to let yourself heal properly for six weeks etc. I was out by 2pm.
The area that was taken away by the Lletz is tested to see if it has clear margins, which means all the pre-cancerous cells as well as healthy cells can be seen on the sample to ensure they have got it all. It takes a few weeks for the results to come back and if there isn't clear margins, I will probably have to go another time to repeat the process.
Hope this was helpful to you and good luck for April xxxx
