Funny how everything these days is diagnosed as IBS. I went through the exact same thing. I also have sphincter of oddi dysfunction (SOD). Have you ever had gallstones? Dilation of your bile duct is typically caused by gallstones passing but if you have SOD it can cause it as well. Unfortunately either way a scope (down the mouth) is likely in your future. If its gallstone cause they can just take your gallbladder out. They can do that now with some holes in the belly. If it is SOD, then they can go in and cut the sphincter so it cant restrict down and cause back up of bile. Sisty and I have definetely been through the long hall, so feel free to ask away.

Speaking of Sisty, happy to tell you after my long long looooong hall, I have been pancreatitis free since August. Thank god the stenting finally helped. !!!!!!! Just thought I would share.
