Welcome to Mayo Connect!
I hope you’ll hear from other members with similar problems- there are many of us with confusing GI issues.
I have been through most of the testing and treatment steps you describe.
Life after gallbladder removal has not been easy- I had to learn what fats I definitely could not eat. I also ended up with sludge in the bile duct - had 2 procedures to enlarge the opening into the intestine. Because of blockage I also ended up with chronic pancreatitis.
Have you had follow up ultrasounds to check the common bile duct?
I’ll just mention another problem I had that’s not very common but caused all symptoms you mention plus others. It’s MALS- blockage of the celiac artery. Caused pain, nausea, lack of appetite, fullness etc.
Let’s wait to see what other members have to share.
