Revision to band vs. DS
There are very few surgeons that do the RNY to DS as it is a very hard surgery and you want the most experienced. I had a band and wouldn't wi**** on my worse enemy. There are a couple here with the BOB and they are doing well. The thing is most of them haven't had them long enough to start having the issues. The manufacture has come out and admitted they are a temporary and will need to be replaced. I haven't heard of anyone making it 10 years with out issue. The DS would be a permanent revision with much better results.
You might want to post this on the DS boards. If you post it on the band boards you will find them very negative and for good reason.
