Sleeve Gastrectomy

laparoscopic sleeve gastrectomy procedure illustrationCommon answers to questions about Sleeve Gastrectomy

Sleeve Gastrectomy is a laparoscopic surgical procedure in which the stomach is remodeled into a long tube about one-quarter the size of the original stomach. During the procedure, staples are placed across the stomach to create the new smaller reservoir, permanently dividing the stomach. A portion of the stomach is removed. Fewer calories are absorbed as your stomach is now restricted in size. The procedure permanently reduces the size of the stomach. This is not a reversible procedure.

What happens during the gastric sleeve surgery?

During gastric sleeve surgery, the surgeon removes about 85 percent of the stomach so that it takes the shape of a tube or sleeve. This procedure restricts the amount of food you can eat, but does not affect the digestive process. The surgery is performed laparoscopically. How big will my stomach be after surgery? 

The size of your stomach will vary depending on the surgeon. Surgeons use a tube to guide them when stapling the stomach. This tube size can vary from 1-2 ounces to 6-8 ounces. This is a very important question to discuss with your surgeon prior to surgery. (Back to Top) (Index of Questions)

What are the major risks of this surgery?

  • Reflux/GERD
  • Abdominal hernia
  • Chest pain
  • Collapsed lung
  • Constipation or diarrhea
  • Dehydration
  • Enlarged heart
  • Gallstones, inflammation of the gallbladder, surgery to remove gallbladder

Is removing the stomach safe?

This type of stomach removal has been performed since the mid 1980s. It does involve stapling, just like in the gastric bypass and has similar risks.

What is a hernia and what is the probability of an abdominal hernia after surgery?

A hernia is a weakness in the muscle wall through which an organ (usually small bowel) can advance. This is a rare complication after the laparoscopic approach, but somewhat common (20% incidence) following open surgery.

Can I stretch out my stomach if I eat too much?

Yes, you can. It’s important to be aware of when you begin to feel full and to stop eating at that point (Back to Top) (Index of Questions) 

Will I need to take vitamins?

While there is no intestinal bypass with this surgery to cause a vitamin deficiency, the procedure is quite restrictive and most surgeons recommend that patients take a multivitamin and calcium. Your surgeon may recommend others based on your specific needs. (Back to Top) (Index of Questions)
