Sleeve Gastrectomy is a restrictive technique which consists of removing approximately two thirds of the stomach and, in particular, the part containing the cells that secrete the hormone that stimulates appetite (ghrelin). The stomach is reduced to a vertical tube and food passes quickly into the intestine. Appetite is also reduced. This technique does not interfere with the digestion process.
Sleeve gastrectomy is sometimes the first step in a biliopancreatic diversion procedure.
