I have had my band since 2003. I planned on getting a revison in Mexico, but I'm terrified because of how old my band is that I'll have a leak past the 4 days in Mexico. Considering getting band out (which insurance will pay for, just not the sleeve) then at later date do sleeve. Does anyone have any info on old banders that did a revision and how much scar tissue etc. Or reccomendations on doing it at one time or separately? Just don't know what to do. HELP!
