Gastric Sleeve
During gastric sleeve surgery, also known as sleeve gastrectomy, most of your stomach is removed. As with gastric bypass, the smaller, sleeve-shaped stomach that remains is sealed and holds smaller amounts of food.
Risks & Considerations Related to Bariatric Surgery (includes gastric bypass (stomach reduction surgery), sleeve gastrectomy and duodenal switch): leaking and/or narrowing at the spot where two parts of the bowel were reconnected, leaking from where the bowel is cut, malnutrition, dumping syndrome (food moves too quickly into small intestine), dehydration, need for supplementation of vitamins, minerals and protein.
Contraindications to endoscopic surgery include morbid obesity.
