A Plication is just sewing/stitching. The Doctor stitches the upper part of the stomach (folds it over) the Band & sutures 12-13 stitches. This is similar to the sleeve as well
If a person's band slips with this Plication then surgery is required to fix the band. Without the Plication & surgery is not usually required with a slipped band, they just take the Fluid out & in most cases the band goes back into place & no surgery is required. I work for Bariatric Surgeons who did the Plication w/ Banding for many yrs but stopped, because when patients slipped their band, off to to operating room.
I was banded 12/22/10 & had the option of Plication but decided not to. I slipped a yr later & was happy the band went back into place (which is common) on its own. Thus far I've been good & have lost 100lbs. My goal is 150 & I'm at 163lbs at present.
Good luck, much success, & congrats to you on ur weight lost
