What Causes Jaundice Post Laparoscopic Cholecystectomy?

I just had my gallbladder out, and well i am still in the hospital. Ive been here for sevral days and im having a mri on monday. My eyes are still yellow though it is mild, and I was jaundiced before surgery, but it disappeared like 2 hours before surgery. Now that my gallbladder is out i still have jaundice , dark urine, yellow eyes. And my bilirubin levels are unstable, sometimes it goes up and then down. I am concerned of the results of the MRI so to be prepared, can someone tell me possible causes of jaundice with no pain after laparoscopic cholecystectomy. I am feeling okay now, like I said, it does not have any pain. I also have inactive hepa B . Could it be that a stone is still inside me. But wouldnt that usually cause pain?
