I was so relaxed until I was sitting outside the theatre talking to the anaesthetist lol he said you’ll be ok I felt a slight pain (cannula being put in arm) and then the next thing I remember is being told operation was a success (the operation for us takes like 2 seconds haha) the one thing I wish I understood more was the two drains my surgeon left in - 1 through nose to stomach was fine no issues 2. Drain out of stomach port for blood was awful, just sat badly and was the cause of great pain for 24 hours until removed (routinely removed not due to my complaining) nurses thought I was being a sook but realised when the drain was taken out it was the drain. If I had known it was the drain and not gas, I would have been more forceful about my needs at the time.
Overall though - now one week later - it’s pretty straight forward. Best of luck.!
