There are certainly cases where possible complications from surgery may lead to your symptoms. I agree with the MRCP you obtained. An ultrasound can also be done to look for biliary duct damage. Discussing this option with your surgeon should be considered.
I would also consider upper GI diseases like GERD, an ulcer or inflammation of the upper digestive tract. An upper endoscopy can evaluate these options.
These options can be discussed with your personal physician or GI specialist.
Followup with your personal physician is essential.
