Revision ? sleeve or bypass
The sleeve for the reasons HisLady and clpeltz gave! Except the healing IS faster with the sleeve than RNY or DS. Sleeves are good to go 2-3 weeks faster.
The first surgery the only choice I had was band or RNY. I did the research and didn't want the RNY I didn't want to lose my pyloric valve. I also didn't want to have malabsorption of calories for only a couple years but, malabsorption of vitamins for life. I also wanted to be able to take NSIDS. So I went with the band until I had medical issues with it.
Now I had a choice of RNY and Sleeve. I still didn't want the same issues with the RNY and I also still want to be able to take NSIDS.
Good Luck with what ever you decide.
