Surgery Options

At the Guthrie Weight Loss Center, our fellowship-trained bariatric surgeon offers three surgical weight loss options. Each option comes with its own benefits and side effects; our surgeon will work with you to decide on the best course of action, based on your medical conditions, overall health and desired weight loss.

All weight loss surgery options are offered laparoscopically, or minimally invasive. When compared with open surgery, minimally invasive surgery offers several advantages, such as less pain, a shorter hospital stay, fewer infections and an earlier return to daily activities.

Our program also offers revisional surgery for patients who have had weight loss surgery in the past.

Our goal is to help you achieve significant weight loss, maintain a healthier weight and improve overall health by decreasing any weight-related health issues.

Laparoscopic Adjustable Gastric Band

LAP BandAn adjustable band buckles around the top of the stomach, narrowing the opening to the remainder of the stomach. In surgery, the band is placed at the top of the stomach, creating approximately a one ounce “pouch” where food enters the stomach. The band has a balloon on its inner surface, allowing the size of the opening to the lower part of the stomach to be adjusted. The adjustments are done by inserting a needle into the port underneath the skin of the abdomen; the port is connected by tubing to the balloon on the inner surface of the band. Injecting more fluid causes the balloon to inflate and narrows the channel for food. Removing fluid deflates the balloon and widens the channel for food to pass through. The concept is to create anatomy that “tricks” the body into thinking that “I’m full and satisfied” when only the small pouch above the band is full, providing a sensation of fullness after a very small meal.


  • Reversible.
  • Least invasive of the surgical weight loss options.
  • No cutting or stapling of the stomach or intestines.
  • Low risk of malabsorption (inadequate absorption of food and nutrients).


  • Weight loss is slower and often less than that of other weight loss surgery options. Estimated excess body weight loss of 30 – 50 percent.*
  • Patients will need to be seen every six to eight weeks for the first year or so after surgery for band adjustment.
  • May not be appropriate for patients with reflux disease.
  • The band is a foreign object to your body. Therefore in rare cases it may break, malfunction, or cause other problems such as a slip, erosion, or infection.

Laparoscopic Sleeve Gastrectomy

Vertical Sleeve Gastrectomy ProcedureThe vertical sleeve gastrectomy (also called sleeve gastrectomy) is a stapling procedure in which approximately 80 percent of the stomach is removed. This results in a tubular stomach, or “sleeve,” that will hold approximately 3 to 4 ounces of food or drink. The amount of stomach left behind is calibrated with a sizing tube, to ensure an evenly sized channel for food.

The Sleeve Gastrectomy works in several ways:

  1. It reduces the size of the stomach, thereby limiting how much food and liquid you can eat in one sitting.
  2. The operation also imparts a beneficial effect on gut hormones – resulting in suppressed hunger, reduced appetite, and improved satiety
  3. The combination of these factors allows you to eat less and feel full sooner, thereby helping you lose weight


  • Rapid and significant weight loss
  • More weight loss than adjustable gastric band (approximately 50 – 70% excess weight loss)*
  • Low risk of “dumping syndrome” – symptoms of weakness, stomach discomfort, and diarrhea after meals
  • No foreign objects placed in the body
  • No rerouting of the intestines
  • Compared with Gastric Bypass:
    • Lower risk of malabsorption (not getting enough nutrients, vitamins, and minerals in your diet)
    • No risk of internal hernia (bowel getting caught in between intestines in the abdomen)
    • Lower risk of bowel obstruction, ulcers, and other problems


  • Not reversible.
  • May not be appropriate for patients with reflux disease.

Laparoscopic Roux-en-Y Gastric Bypass

Gastric Bypass ProcedureThe upper portion of the stomach where food first enters is stapled and separated from the remainder of the stomach. This stomach “pouch” holds about 1 to 1.5 ounces, limiting food intake by causing a feeling of restriction or fullness with a small amount of food. The small intestine is re-routed to accept food directly from this small stomach pouch. The remaining stomach, duodenum and the initial part of the jejunum stay in place and continue to make digestive juices, but are bypassed.  The new anatomy helps with a feeling of decreased hunger, improved fullness and improved blood sugar regulation. The re-routed intestine also helps some patients make better food choices, because high-calorie foods (such as cookies, cake, candy, sweets, soda, or high-fat foods) may cause a very unpleasant sensation after eating them.


  • Generally results in the highest amount of excess weight loss, 60 to 80%*
  • Significantly improves diabetes and reflux disease
  • Works by restricting amount of food and liquid intake, and limiting absorption of nutrients in the Gastrointestinal tract
  • Produces favorable changes in gut hormones that reduce appetite and enhance satiety
  • Typically maintain weight loss over long term


  • Difficult to reverse.
  • Possibility of dumping syndrome, ulcer, nutrient deficiencies, hernia, bowel obstruction and other complications.
  • Patients must take nutritional supplements for the remainder of their lives.

*This is not an absolute number or guarantee of expected weight loss. Patients may lose more or less weight depending on their individual circumstances. The patient's own efforts (such as eating a healthy diet and making positive lifestyle and behavior changes) will also impact how much weight is lost after any bariatric procedure and whether any weight is regained in the long-term.
