Vertical Gastric Sleeve
The vertical sleeve gastrectomy is a restrictive form of weight loss surgery in which approximately 85% of the stomach is removed leaving a cylindrical or sleeve shaped stomach with a capacity ranging from about 60 to 150 cc, depending upon the surgeon performing the procedure. Unlike many other forms of bariatric surgery, the outlet valve and the nerves to the stomach remain intact and, while the stomach is drastically reduced in size, its function is preserved. Again, unlike other forms of surgery such as the Roux en Y gastric bypass, the sleeve gastrectomy is not reversible.
Because the new stomach continues to function normally there are far fewer restrictions on the foods, which patients can consume after surgery, albeit, that the quantity of food eaten will be considerably reduced.
This is seen by many patients as being one of the great advantages of the sleeve gastrectomy, as is the fact that the removal of the majority of the stomach also results in the virtual elimination of hormones produced within the stomach, which stimulate hunger.
- Anytime you have anesthesia or surgery, there is a risk of blood clots, other complications or death.
- Do not smoke. Smoking would put you at high risk for infection, blood clots, slow healing and other life-threatening complications.
- Complications can occur with the stapling, such as leaks or bleeding.
- You may need malabsorptive surgery – intestinal bypass or duodenal switch – in addition to your sleeve gastrectomy in order to lose all the weight you need and want to lose.
- The smaller portion of the stomach may stretch.
- Foods that you eat now may cause discomfort, nausea or vomiting after your surgery.
- Gastric surgery puts you at higher than normal risk of developing gallstones and gallbladder disease.
- You will not lose weight or maintain your weight loss unless you eat a healthy diet and exercise regularly.
- This is the reason we stress long-term follow-up with our center and your doctor.
- Sleeve gastrectomy may be safer than gastric bypass for patients who have a number of health risks.
- It lowers the risk of ulcers compared to gastric bypass.
- The surgery cuts away the part of the stomach that produces grehlin, a stomach hormone that stimulates hunger.
- Though the stomach is smaller, the openings are left intact, so digestion can go on as normal.
- The body is free of foreign objects like the LAP-BAND® or Realize Band.
- May be converted to gastric bypass or duodenal switch if necessary for additional weight loss
- Expected excess weight loss for stand-alone procedure is 60 to 70% at two years
