Sleeve gastrectomy is a restrictive bariatric surgery. During this procedure, the surgeon removes approximately 60-70% of the stomach. This leaves a small, sleeve-shaped stomach that is about the size of a banana. The mechanism for weight loss is gastric restriction, as well as neurohormonal changes due to lower levels of ghrelin, an appetite-stimulating hormone produced by the fundus. Because the new stomach continues to function normally there are fewer restrictions on the foods which patients can consume after surgery, although the amount of food eaten will be considerably reduced.
Advantages of the sleeve gastrectomy
- Average sleeve patients will lose approximately 70% of their excess body weight within two years.
- The stomach is reduced in size and the amount of food that can be eaten is restricted. Otherwise the stomach functions normally.
- The major part of the stomach which produces hormones responsible for stimulating hunger is removed from the digestive system.
- The problem of “dumping” is avoided as the pylorus (muscle between the stomach and small bowel) is not altered.
- Minimizes the possibility of the patient developing ulcers, especially in those patients who take occasional NSAIDS (ibuprofen, advil, aleve for example).
Disadvantages of the sleeve gastrectomy
- Sleeve gastrectomy is permanent and not reversible.
Risks/Complications related to the sleeve gastrectomy
- Standard risks associated with surgery, like pain, bleeding, blood clots and infection.
- Nausea and vomiting.
- Leakage and/or bleeding at the suture/staple line.
- Development or worsening of gastrointestinal reflux disease (GERD) and heartburn.
- Vitamin and protein deficiency
