Gastric sleeve surgery is the procedure of the removal of a little more that half of the stomach so that it takes the shape of a tube or sleeve. It is performed through laparoscopy and requires stapling and resecting, though it does not require any rerouting. I am very afraid of this surgery. I knw something was wrong as I was vomitting all the time, but now that I have been defilled, I'm not vomitting, however, I'm not feeling any restriction when eating and so am afraid that my weight will come back on. The doctor performed a gastroscopy on me and that's how he discovered my band had slipped. Right now I'm in a "wait & see" mode. The doc wants to see how I do without the fill. I had 5.5 cc and he took out 4.5 cc.
