Band Slippage

I was banded in 2005, this past June I started having frequent vomiting. I was in the process of moving and thought this was r/t stress. Well finally got sick of all the vomiting and found a surgeon in Anchorage. He with drew the fluid in the band and did an X-Ray. Removal of the fluid didn't seem to make any difference, the doctor called today to say that "the x-ray show a high probability of band slippage". So now I have to have an upper GI. My problem is I had acute coronary syndrom and had a stent placed in Aug. so now I can't have surgery to fix the band for six months.  Has anyone had a band slip? Is the repair similar to the band placement, do they put in a new band? Anyone know?
