Everyone posted a lot of good info. Like you, I at first was going to get the LapBand. After researching it, I basically learned that:
While the initial complication rates for the band were lower, the long term complication rate was much higher
I figured that I would rather have a surgery and "get it over with" in the first couple months of healing than deal with a lifetime of getting stuck with a needle in my stomach. (this costs money too)
The difference in complication rates, even initially, between the sleeve and the band were really almost nothing. I think the band has an initial complication rate of 0.05% and the sleeve of 1%. It's still very, very small.
The bariatric surgeons I've talked with have all preferred the sleeve for me over the band.
Plus, if the band fails, it gets revised to the sleeve. I just thought--why not get it right the first time? I don't want two surgeries.
