Yes it is amazing, and I believe from your description, you are talking about endoscopic surgery. I'd never heard it called "keyhole" before but I suppose that makes sense!

Yes, Private Carers is an extra forum but only for carers, no one else has access. It was quite quiet in there for a time, but it has had a resurgence of activity of late. If you wish to join, click on the "user cp" button, then on the side, click "group memberships", and from there you should see an option to join the group. I will approve you naturally.
