any info on revision surgery docs in oregon, revision costs, revision info at all for oregon??

I'm looking into revision surgery & would like to know whai professionals I can talk to about it in Oregon. I had rny at legacy good Samaritan in Portland, or in 2008 & got pregnant very soon afterward which made weightloss extremely slow going. I regained a lot & am hoping to get some type of revision surgery. When I last saw the surgeon, recently for follow up, I asked her about the ROSE procedure, and she said she doesn't do that. After further research, I am leaning now toward revision to GS from RNY. I don't think they do any kind of revision there, but would like to stay with them, however, if they don't do it, I need to find a hospital that does. Please help!!

I believe they do revisions at OHSU.  Here is a link to their site:
