Don’t know.
But this is very, very specific - ERCP, which is a very specific procedure; as I said, not just any endoscopy. I’d tend to worry more about other endoscopic procedures being tainted before worrying other totallly different areas. It has to get past the stomach to the GB and duodenum, so it’s really the same general location they are working.
Do not know why it is very specific to this procedure.
Probably some illegal passed it off onto an ERCP and it has gone from there....
I read some time back that the “butt” scopes were (in some instances) getting what amounted to a quick wipe (sorry for that ha ha) with alcohol before getting used again.
