Laparoscopic Sleeve Gastrectomy : Video and Concept



  • Laparoscopic sleeve gastrectomy is a restrictive procedure without the malabsorptive component
  • It involves resection of two-thirds of the stomach to provide increased satiety and decreased appetite.
  • Through restriction in the stomach size, the intragastric volume is less able to accommodate a large volume of food leading to decreased food consumption. 
  • In addition, a lower volume of food leads to earlier distention of the stomach causing firing of stretch receptors in the gastric wall. 
  • These signals are communicated via the vagus nerve to the nucleus tractus solitarius in the brainstem which then signals to the hypothalamus and then the cerebral cortex leading to the perception of satiety.
  • Decreased levels of ghrelin that occur as a result of resection of the gastric fundus, the location of ghrelin production, also likely leads to greater satiety.
