Gastric Sleeve surgery, also known as gastric reduction , gastric sleeve resection, vertical sleeve gastrectomy and vertical gastroplasty, is a relatively new form of weight-loss surgery that has gained popularity in Mexico and United States in the recent years with many weight loss surgery patients finding success in the procedure as an alternative to laparoscopic gastric band surgery. Gastric Sleeve Surgery corresponds to the first step in the restrictive part for Duodenal Switch, which is a combined procedure so restrictive as Malabsorptive performed in super obese patients.

Gastric Sleeve started to perform in patients with high surgical risk to a duodenal switch could be carried full and they only performed the gastric or restrictive (gastric sleeve surgery, or gastric resection sleeve), without making the Mal absorptive or (duodenal switch). In the long-term observation of patients, we have seen that they lose all their weight without requiring the Malabsorptive Duodenal Switch, for that reason, the Gastric sleeve is considered the gold standard in bariatric surgery, because the patient remains free of long-term overweight as well as associated diseases, such as: diabetes, hypertension, cholesterol, etc

Since only a few cases completed the bad absorptive part of the Duodenal Switch, those patients who had a plateau of their weight loss after 12 to 18 months performed the gastric sleeve.
