Bile acids work by thinning bile, allowing it to flow more readily. The Rx version is Ursodiol and there is a natural health store product called Tudca that is readily available on Amazon. It's worth a try. After my husband's Whipple, he had an issue with bile duct strictures at the anamstosis. His bile was normally kind of sludge-like. Ursodiol helped, but he ended up having a PTC (Percutaneous Transhepatic Cholangiogram) and dilation.
