The Vertical Sleeve Gastrectomy:

An excellent choice for substantial weight loss without the drastic anatomical changes





Why choose the Vertical Gastrectomy?

  • No intestinal bypass or foreign body
  • No adjustments needed
  • Minimizes the hunger/appetite hormone, Ghrelin
  • Extremely effective with weight loss equal or better than the bypass and band
  • Safest for very high BMI patients
    (greater than 400 pounds)
  • No dumping syndrome
  • Great procedure for Low BMI patients (30-40) who often lose >90% of their excess weight


Vertical Sleeve Gastrectomy (VSG) is a newer, innovative weight loss surgery. The Vertical Sleeve (or "Sleeve" as it is commonly known) involves removing 85%-90% of the stomach, without changing the intestinal tract. The new 1-2 ounce pouch that is created significantly reduces the volume of food that can be consumed, while still allowing the stomach to function normally. The part of the stomach that is removed contains cells that produce the hunger hormone, Ghrelin. By drastically reducing the production of Ghrelin, the appetite and sensation of hunger is markedly reduced or eliminated. Our patients have a success rate of >80% excess weight loss which occurs within 1 year.


The sleeve gastrectomy procedure, commonly referred to as the Vertical Sleeve Gastrectomy, vertical gastrectomy or simply the sleeve, is a newer restrictive procedure where the majority of the stomach is removed leaving a long tubular structure from the esophagus to the small intestine.

Vertical Sleeve Gastrectomy is not as common as other bariatric surgeries but it is quickly gaining in popularity.


LapSF: The practice and Surgeons that pioneered the Sleeve Gastrectomy

Since pioneering the VSG in 1999 in our San Francisco Weight Loss Center, LapSF has performed more than 1700 vertical gastrectomies-the world's largest long-term series. The Vertical Sleeve Gastrectomy is becoming the preferred option for many patients seeking surgical weight loss. Because of their world renowned expertise, patients travel from all over the U.S., Canada and even the world to find LapSF's weight loss doctors in San Francisco. Most patients benefit from the biggest advantage of the Vertical Sleeve Gastrectomy-no intestinal bypass. Patients do not experience the complications of intestinal bypass including intestinal obstruction, osteoporosis, anemia, vitamin deficiency and protein deficiency. Vertical Sleeve Gastrectomy is a good option for individuals who are either extremely overweight or whose medical condition would rule out other forms of surgery.

Important advantages about the Vertical Sleeve Gastrectomy:

  • Estimated weight loss >80%
  • Resolution of diabetes >90%
  • Resolution of obstructive sleep apnea >95%
  • Resolution of hyperlipidemia (high cholesterol and triglycerides) >80%
  • Resolution of hypertension >80%
  • The portion of the stomach that produces the hormone that stimulates hunger (Ghrelin) is removed.
  • The stomach is dramatically reduced in volume yet also functions normally.
  • No dumping syndrome because the pylorus is preserved.
  • Minimizes the potential for ulcer, so the use anti-inflammatory drugs such as aspirin, Motrin, Aleve and ibuprofen are not problematic (great procedure for those with arthritis, joint pain or migraine headaches).
  • No intestinal bypass and therefore little or no chance of nutritional and vitamin deficiencies
  • Most patients with BMI between 30-50kg/M2 achieve their goal weight within 12 months following surgery.
  • Safer alternative for high body weight (>400 pounds) or medically high-risk patients than the gastric bypass or duodenal switch.
  • No foreign body or implanted devices.
  • Can be performed laparoscopically in virtually all patients.
  • 99% leave the hospital within one day.
  • Out of the area and out of state patients easily accommodated and may qualify for airfare and hotel coverage.
