When they took mine out they put the bile duct directly into the lg colon. I had lots of discomfort with diarrhea and now my bile duct has a bubble in it. I go to the GI Dr in one week.

I'd go to the doctor. Something similar happened to me and I wasn't making enough stomach acid post surgery to digest my food

I had mine out in my 30s almost 40 yrs ago. I was told that the bile duct increases size with age, normal. But, My pain is severe when my belly is bloated by gas and stool. I had upper GI, MRI, Ultrasound and Cat Scan. Seems it is irritation at the muscle from the scar tissue that formed over the years. If I drink hot or cold on an empty stomach the pain is bad even without bloating.
