Oh Volans,
I'm really sorry to read that...only goes to highlight the incompetence of some medics out there......but I'm also confused, I had an anoscopy and I had eaten beforehand and I wasn't sedated either! I'm not quite sure what approach your CRS was taking......So, you now have to wait another 2 weeks?
You should be able to see what anoscope they use in your procedure and some instruments are much smaller than others too.
