[Sleeve gastrectomy: a new approach to bariatric surgery]

Over the last 15 years, obesity surgery has developed tremendously. The two most frequently practiced procedures are the adjustable gastric ring and gastric by-pass. A new intervention has recently appeared: the sleeve gastrectomy, an essentially restrictive intervention consisting of a vertical gastrectomy including the entire greater curvature of the stomach while leaving in place an approximately 100-ml gastric tube along the lesser curvature. This intervention was initially proposed as the first part of a duodenal switch in patients whose body mass index was greater than 60 kg/m2. Since then, these indications have developed and this intervention now enjoys a certain fervor on the part of bariatric surgery teams. The objective of this mini-review is to detail the technical aspects of this procedure, its morbidity and mortality, and the long-term results, although there are currently few teams with more than 3 years of experience.
