I just got the band along with plication on August 31. Elcee is right - the plication is an optional procedure where they fold the stomach in on itself and stitch it in place to form a sleeve-like shape. According to my fabulous doc, this does help with band slippage, but most people who opt for it do so because the weight tends to come off faster (results more similar to gastric bypass.). He said it's unknown at this point whether the plication along with the band will result in greater weight loss over time. It was an additional $1500 for me to add the plication and I'm self-pay so I figured while he's in there let's go for it! I have read about some patients who go in for band revision and add the plication so I thought I'd do it all at once. No problems so far but I'm just getting started (banded just a week ago.). I'm glad I did it.
