Bariatric Surgery at Willamette Valley Weight Loss Center

Our weight loss program is designed to fit each person’s unique needs and has helped patients regain their health. Our team includes a bariatric surgeon, dietitian and behavioral health specialists. With follow-up care from our team and support from others on the same path, clients can change their lifestyles and navigate the transition to a healthier weight and a better quality of life. We combine the latest in expertise and technique with exceptional support. Surgical options include the following procedures:

Laparoscopic Sleeve Gastrectomy

Sleeve gastrectomy is a surgical procedure that permanently reduces the size of the stomach. The new “sleeve” stomach is roughly the size and shape of a banana. Reducing the size of the stomach limits food intake and also decreases the production of ghrelin (also known as the “hunger hormone”). Patients feel full faster when eating and have less hunger between meals. Patients eat fewer calories, resulting in weight loss. This is the most popular weight loss procedure currently.

Laparoscopic Gastric Bypass

Roux-en-Y gastric bypass is a surgical procedure that reduces the size of the stomach, similar to the sleeve gastrectomy. Additionally, a portion of the small intestine is “bypassed”, so that less calories are absorbed by the body. This procedure also decreases ghrelin levels in the body, resulting in less hunger and less calorie intake.

Gastric Band Adjustment or Removal

The adjustable gastric band is a device that is surgically placed around the top part of the stomach to create a small “stomach pouch”, thereby limiting food intake. The gastric band is less effective than either sleeve gastrectomy or gastric bypass. We do not offer placement of new gastric bands, but we do offer adjustment of existing gastric bands as well as gastric band removal.

Revisional and Conversion Procedures

A revision or conversion procedure is a surgical procedure to modify or correct a previous bariatric surgery, or to convert one procedure to a different procedure (such as a sleeve gastrectomy to a gastric bypass). The most common reasons for revision or conversion procedures are insufficient weight loss, weight regain, and complications of the original surgery, such as acid reflux. These procedures are performed on a case-by-case basis.
