Minimally Invasive Weight Loss Surgery

Weight Loss Surgery Webinar

Guthrie Weight Loss Center offers three surgical weight loss options. Based on your medical conditions, overall health and desired weight loss. Our fellowship-trained bariatric surgeon works with you to decide the best procedure.

Surgeries are performed laparoscopically through several small incisions in the abdomen. The procedures are considered minimally invasive.

Advantages of laparoscopic surgery compared with open surgery:

  • Less pain
  • Shorter hospital stay
  • Fewer infections
  • Earlier return to daily activities

Bariatric Surgery Options

Our fellowship-trained bariatric surgeon offers three surgical weight loss options. All weight loss surgery options are offered laparoscopically, or minimally invasive.

Laparoscopic Sleeve Gastrectomy

Vertical Sleeve Gastrectomy ProcedureThis procedure involves removing a portion of the stomach, leaving patients with a sensation of fullness after eating smaller portions. Scientific studies show a decrease in hunger due to changes in gut hormones (ghrelin and other GI hormones).


  • Rapid and significant weight loss
  • More weight loss than adjustable gastric band (approximately 50 – 70 percent 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.

*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.
















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 one to one-and-a-half ounces, limiting food intake by causing a feeling fullness with a small amount of food. Patients also absorb less food, facilitating further weight loss.


  • Generally results in the highest amount of excess weight loss, 60 to 80 percent*
  • 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 enhances feelings of fullness
  • 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.

Laparoscopic Adjustable Gastric Band (LAP-BAND®)

LAP BandThe procedure implants a silastic belt at the top of the stomach, creating a small pouch that holds approximately one ounce. A balloon along the inner surface of the belt can be narrowed or widened by injecting fluid through a port just beneath the skin. The smaller stomach pouch creates 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. In rare cases it may break, malfunction, or cause other problems such as a slip, erosion, or infection.
