Did you have more testing done to find you have an injured bile duct following the surgery? What symptoms are you having with it?
I found this blog interesting. He's a surgeon, and he talks about how he's had to go back and fix the cystic bile duct that other surgeons didn't take care of properly during the surgery.
I had the Hida scan, and my gallbladder was functioning at 5%. Surgery was done the next morning. The surgery was definetly no cure all for me. But, I also didn't know my liver was full of parasites blocking it, plus I didn't know I had active Lyme coinfections then either.
