Our Procedures

Bariatric Surgery Options

There are several different bariatric surgeries available today. At MultiCare, we tailor your care to your individual medical needs to ensure the best results possible. As a result, we perform several different bariatric procedures.


This procedure creates a small stomach pouch with a stapling device. A section of the small intestine is then attached directly to the pouch. This allows food to bypass a portion of the small intestine.

By creating a smaller stomach pouch, a gastric bypass limits the amount of food that can be eaten at one time, so you feel full sooner and stay full longer. By bypassing a portion of the small intestine, your body also absorbs fewer calories. As you eat less food and absorb fewer calories, your body will stop storing excess calories and start using its fat supply for energy.


During the sleeve gastrectomy procedure, a thin vertical sleeve of stomach is created using a stapling device. The sleeve is about the size of a banana. The rest of the stomach is removed.

Like gastric bypass surgery, a sleeve gastrectomy creates a smaller stomach pouch. This limits the amount of food that can be eaten at one time, so you feel full sooner and stay full longer. As you eat less food, your body will stop storing excess calories and start using its fat supply for energy. Unlike a gastric bypass, however, this procedure does not bypass any of the small intestine, so it does not affect the calories you absorb from the food you eat.

Duodenal Switch and SIPS-Duodenal SwitchCWLW DUODENAL SWITCH

In duodenal switch (DS), the majority portion of the stomach is removed (as in the sleeve gastrectomy). The lower intestine is then divided, leaving a few feet of intestine where food and digestive enzymes meet. The name duodenal switch comes from the fact that the intestinal bypass starts at the duodenum, which is the first part of the intestine. The duodenum is divided and attached to the lower portion of the small intestine, the ileum. 

CWLW SIPS DUODENAL SWITCHStomach intestinal pylorus sparing duodenal switch (SIPS-DS) is a simple variation of the traditional DS.

DS and SIPS-DS help to achieve weight loss using dual components of this operation—restriction of food consumption as well as malabsorption.

DS and SIPS-DS are typically most appropriate for patients whose BMI is greater than 50.

Revision Bariatric Surgery

A variety of revision bariatric procedures can be performed, including (but not limited to):

  • Removal of adjustable gastric band (with or without conversion to an alternate procedure)
  • Revision of vertical banded gastroplasty ("stomach stapling")
  • Revision of sleeve gastrectomy
  • Revision of gastric bypass

After consulting with a surgeon, you'll be referred to complete tests and imaging exams to assess your current anatomy. After these items are complete, you'll return to the clinic to discuss your results and an operative plan can be established if surgical intervention is necessary and/or desired.
