I also had an erosion and almost died. I had revision surgery in August, to a gastric bypass, and couldn't be happier. However, the doctor spent the first two HOURS of my surgery picking pieces of a disintigrated band out of my stomach wall. I probably had weeks left to live only.
I was very lucky. Now, however, I am truly happy again. To me, the difference between these two surgeries is night and day. I never got anywhere near close to goal after lapband. The gastric bypass is an absolute dream come true. I have lost 79 pounds in 5 months and am wearing a size 6-8. I've still got a little more to lose, but I have my health back, and hope for being thin, real hope, for the first time. Reoperation rates, long term, 8-12 years out, for lapband are VERY high.
