Anyone had problems with your liver after surgery?

I had my surgery in April 07 and 2wks postop I started urinating brown so I went to my primary dr to find that I had extremely high liver enzyme levels and they put me back in the hospital for more tests.  They could find the reason but my liver was dumping bile into my system rather than into my intestine.  After about 6 months I was feeling more normal and it seemed to have healed itself.  I went yesterday for pre-op blood work to start some plastic surgery and they called this morning that my liver enzymes where climbing up again.  I called my WLS surgeon and he is setting up an appt with a liver specialist.
I have never had any liver problems before the surgery.
Anyone else having problems?
