SW, yes, it could be a bile duct problem...or diverticulitis...or.... The only way to find out is with a colonoscopy (to rule out intestinal problems) or an MRI to check for liver cancer or something else else lurking on the inside. Bile problems do seem to go along with ESLD.
You'll probably just need to wait until he collapses and goes to the ER to find out what is really going on. Or maybe the doctor can tell you something on Thurs. Let us know!
