Ian-- best wishes, today and whenever they do it.
Lurkers- I too had a gall-job, last year. UK practice is different from the US. I had less than 2 hours of pre-op consult and testing. On the assigned day I went in at dawn, was awake by 10, sent home at noon. My designated driver was ordered to make me rest all day; but I felt fine and was hungry.
I may have been told to avoid lifting more than a gallon for a couple weeks, but this may be boilerplate. My assessment is that I was 99% ready for anything. Certainly nothing like the appendicitis filet-job (not a McBurney's) I had some years before. Gall-job was like I'd been in a knife-fight, with a letter opener, which didn't hit anything I needed. Big deal.
Over the weeks I had healing itch and odd twinges, much less than expected.
You would expect digestive upset, and some folks do, I didn't.
> You will probably be awake and able to post while they do it...............just kidding
That's what I thought. They used to knock-out for a colonoscopy, now they don't (here), and you get to watch. But for the gall-job I was told "you do not want to be awake". One reason is that the gall-stuff is packed tight like some wretched amplifier chassis we know. They inflate your gut-cavity to get some space to work in. That's some of the twinges I felt after.
