Able to get gastric sleeve after lap band surgery and open lap band revision surgery due to slippage?

I had the lap band done in 2002, lapiscopocally, lost 90% of my excess weight, then had it slip had a lap band revision 1.5 years later, it was done open due to adhesions. I was too scared at that point and had the fill taken out, I have since regained all my weight. Would I be able to get the band removed and have a gastric sleeve? Would it have to be done open . I have a horrible scar from the band revision. Keloid.
