Bariatric Surgery Options

There’s a large, sometimes confusing array of weight-loss procedures out there today. At MultiCare, we choose to offer several of the safest and most effective weight-loss surgeries available. This range of options lets us address your individual medical needs to ensure the best results possible.


Weight-loss surgery works by reducing your stomach size, bypassing part of your digestive system so you absorb fewer calories, or both. Roux-en-Y gastric bypass causes weight loss both ways.

In Roux-en-Y gastric bypass, your surgeon uses a stapling device to create a small stomach pouch. He or she then attaches a section of your small intestine directly to the pouch. This way, your food will bypass part of your small intestine and you’ll absorb fewer calories. Plus, with the smaller stomach pouch, you’ll only be able to eat a small amount of food before feeling full. You’ll begin using your body’s stored fat for energy.


Like gastric bypass surgery, in a sleeve gastrectomy, your doctor uses a stapling device to reduce your stomach, creating a banana-shaped sleeve. After surgery, you’ll be able to eat less food at once, and you’ll feel fuller sooner and longer. Your body will start using its fat supply for energy.

Unlike a gastric bypass, however, sleeve gastrectomy does not bypass any of your small intestine. You will still absorb the same number of calories and nutrients from the food you eat.

CWLW DUODENAL SWITCHDuodenal Switch and SIPS-Duodenal Switch

If you have a BMI of 50 or more, your doctor may recommend a duodenal switch or SIPS-duodenal switch surgery. Both these procedures greatly reduce the amount of small intestine your food travels through.

Your small intestine has two parts, an upper part called the duodenum and a lower part called the ilium. In a duodenal switch procedure, as in sleeve gastrectomy, your surgeon removes most of your stomach. He or she then divides your ilium, leaving a few feet of intestine where food and digestive enzymes meet. Then your surgeon divides your duodenum and attaches the duodenum to the ilium, creating a much shorter passageway for food.

After duodenal switch surgery, you’ll absorb many fewer calories from food. And as in other weight-loss surgeries, you’ll be able to eat less food at once. Instead, you’ll feel full after eating small meals, and you’ll begin burning stored fat for energy.

CWLW SIPS DUODENAL SWITCHStomach intestinal pylorus sparing duodenal switch (SIPS-DS) is a simple variation of traditional duodenal switch surgery. In both procedures, you lose weight because you can eat less food and you absorb fewer calories from the foods you do eat.

However, in SIPS-DS, your surgeon only separates your small intestine at one point, not two. This spares the pylorus, which is the connection that empties your stomach into your small intestine, as well as a larger part of the small intestine.

Revision Bariatric Surgery

Sometimes, people find that their first weight-loss surgery isn’t as effective as they want, or they have problems with the procedure. In these cases, they may select a second bariatric surgery, known as revision surgery. Types of revision surgery include:

  • Removal of adjustable gastric band (with or without conversion to an alternate weight-loss surgery)
  • Revision of vertical banded gastroplasty, a procedure also known as stomach stapling
  • Revision of sleeve gastrectomy
  • Revision of gastric bypass

If you think you may need revision surgery, you’ll have an initial conversation with your surgeon. Then you’ll complete a series of tests and imaging exams so your surgeon can know exactly what’s going on with your body. After your surgeon has reviewed your tests, he or she will work with you to decide whether you need a revision procedure, and, if so, which one is best for you.

Which Option is Right for You?

Each surgery has its advantages. Your surgeon will discuss these procedures with you in detail, including risks and complications, and he or she will recommend the surgery that is best for you.
