Hi there,
This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.

Sphincter of Oddi dysfunction can precipitate postcholecystectomy syndrome.
There is a possibility of a growth or obstruction at the opening of the sphincter of Oddi--this is where the pancreatic duct opens into the duodenum.
Sometimes bile stone can cause this blockage.
Also excess bile acid circulation through the intestine in the absence of gallbladder can precipitate similar symptoms.
To check the sphincter of Oddi dysfunction or biliary dyskinesia you will need a test specialized to look inside the duct.
MRCP is one such good test --a noninvasive test by MRI but specially focused to check the pancreatic duct and sphincter od Oddi.
Sphincter of Oddi manometry is another good option.
ERCP is another test which is invasive that can be considered as well.
Best wishes,
