Kevin, seriously - she's telling you her doctor acts like she's fine and he's done with her. Why not tell her to go find another doctor, a better one, that will implement these tests. Should the patient really have to find out what tests are needed and then go ask their doctors if they'll give them the tests? Shouldn't they know to do that already!?
You have had a pretty comprehensive evaluation of the symptoms, including both an ultrasound and CT scan, as well as undergoing gallbladder surgery.
Indeed, in some cases, a low gallbladder ejection fraction can lead to some of these symptoms. But, not all cases improve after surgery.
Regarding the pancreas, if this organ is suspected of having disease, then an abdominal MRI and/or an endoscopic ultrasound can be considered.
If the tests remain negative, more specialized tests, including a gastric emptying scan, esopgaheal motility studies, or blood tests looking for celiac disease can be considered.
Also, with the changes in stool size and shape, a colonoscopy should be considered as well.
These options can be discussed with your GI physician.
