katkat...Yes, St. B has a gastro clinic. It's a teaching hospital and I believe some research.
I don't know about
needing an ercp, but you would if there are stones stuck in the pancreas or bile ducts. Hope they get them all and that you're not like my sister and make them all on her own without a gallbladder..lol.
If you get it done in the city...I would love to visit you
Hope you don't have too many bad gallbladder pain days!
Keep us posted.
