Masters Program Bariatric Pathway: Laparoscopic Sleeve Gastrectomy

  • Michel Gagner


Laparoscopic sleeve gastrectomy (LSG) – a gastrectomy of the fundus, body, and proximal antrum, to create a longitudinal, partly vertical, cylindrical gastric conduit constructed along the lesser curve of the stomach – is presently the most performed bariatric/metabolic intervention in the United States and worldwide. Three years ago, it surpassed standard Roux-en-Y gastric bypass. It is used to treat morbid obesity (BMI > 40 kg/m2), severe obesity (BMI > 35 kg/m2) with associated comorbidities, and type 2 diabetes in lesser degree of obesity (metabolic surgery) and often used as a bridge for high-risk patients before a more malabsorptive surgery or before other types of surgery where weight is a hindrance (transplantation, joint replacements, deep pelvic surgeries among the commonest). In this chapter, we review the technical aspects and controversies related to this new innovative and popular minimally invasive surgery.
