The plication is the inverting of the stomach and stitching to create a sleeve affect. That is why I have more weight lost. The lapband along with the plication helps with more weight loss.
Yes some of the stomach is holding the band in place. This procedure is rather new, so there's not alot of information as far as statistics. When I was told that I could lose as if I had gastric I knew lapband plication was for me.
