I'm 3 weeks post op revision from Band to RNY and my surgeon removed the band and then did my RNY at the same time.
I originally wanted the Duodenal Switch, but I have health issues that make that not an option for me, so I went with the RNY. I had horrendous acid reflux, which would not have been cured with the sleeve. It has completely resolved with having had the RNY (it's the re-routing that fixes the reflux issue) that alone made having RNY worth it!!!
My band was empty for 3 yrs and I still had horrible acid reflux and regained 50 lbs of the 100 I lost. I ended up waiting till I got new insurance that covered removal and revision, but it was hell having to wait so long.
The Band is being phased out by a lot of practices and is being replaced by the sleeve. They are taking out Bands left and right now. You may want to check out the DS, RNY and sleeve boards and see what those peeps have to say about their specific surgery.
The most important thing is that you decide which surgery will work best for YOU, and than go with it.
I'm not due to get weighed again till Monday, but so far I'm down 26 lbs and 2 clothing sizes, and that definitely is working for me!!!
