Sleeve Gastrectomy
Laparoscopic Sleeve Gastrectomy
Restrictive Procedure
This procedure generates weight loss solely through gastric restriction (reduced stomach volume). The stomach is stapled and divided vertically, with more than 85 percent of it being removed. This part of the procedure is not reversible. The remaining portion of the stomach is shaped like a very slim banana and measures bewteen 1-5 ounces (30-150cc), depending on the surgeon performing the procedure. The nerves to the stomach and the outlet valve (pylorus) remain intact with the idea of preserving the functions of the stomach while drastically reducing its volume.
This is a relatively new procedure that can be used as a standalone procedure for those who have a BMI <35 or as a staged procedure for high-risk patients with a BMI >40. The advantages to this type of proecedure is that there is a low risk of malnutrition and no diarrhea, anemia, dumping syndrome or vitamin loss therefore it is an alternative for patients with anemia, Crohn’s and other conditions that make them too high-risk for intestinal bypass. This procedure often produces slower initial weight loss which may be a disadvantage for some.
Complications of Laparoscopic Sleeve Gastrectomy may include:
- possible leak that may require surgery
- Bleeding
- Embolus (blood clots)
- Respiratory (pneumonia)
- Infection (always higher when the bowel is opened)
