It's wonderful to know she's doing better. I'm sure that's a relief to the both of you.
Sorry about not following up sooner. To be honest, I had forgotten that I had posted here. However, I feel I should give an update in the hopes that it may help someone else.
My wife eventually was able to go to a gastroenterologist in Temple, TX. They diagnosed her with Sphincter of Oddi Dysfunction. They performed an ERCP and cut the sphincter muscle which allowed the bile to release into her small intestine. About a couple of months later she started having the same symptoms again. She went back and they did another ERCP and found scar tissue. The stretched the sphincter muscle and this resolved the issue. Thankfully, she has not had any more trouble.
It might be a good time to check in with your doctor. There can be on-going issues with the biliary system even after the gallbladder is removed. Problems can occur immediately afterward, or can happen several years later. You may want to request some testing to be done to visualize the biliary tree and the structures involved. That would be a start.
I forgot to mention, she's 41, she had a complete historectomy about 11 years ago, and is of average weight.
