"Vertical Gastrectomy is emerging as the quickest and most successful obesity-related surgery. Despite the risks inherent to all types of surgery, Vertical Gastrectomy is the preferred method” said Dr. Paul Cirangle, surgeon at the San Francisco Bay Area Laparoscopic Associates. Laparoscopic Associates of San Francisco, where Dr. Cirangle works with San Francisco weight loss surgery experts Dr. Gregg Jossart and Dr. John Feng, is the only group in the Western United States to perform all weight-loss surgeries laparoscopically.

Dr. Cirangle, who authored this one-year study of 166 patients over 50 years old, compared the results of Vertical Gastrectomy surgery with the results of three other kinds of obesity-related surgeries: LapBand, Roux en Y Gastric Bypass, and the Duodenal Switch. In a statement prepared for delivery to a conference of gastrointestinal and other experts in Chicago, Dr. Cirangle said, “It is important for us to know, especially as these surgeries become more prevalent, which operation is best for each patient."

The study found that Vertical Gastrectomy, in which up to 95 percent of the stomach is removed, leaving behind a thin tube-like stomach roughly two ounces (60 milliliters) in volume, was performed in the shortest amount of time, approximately 90 minutes, and had the fewest complications. Patients who underwent this surgery lost an average of 133 pounds (60 kg) after one year, 15 pounds (6.8 kg) more than the next-best surgical method.

More than 300 obesity-related surgeries are performed each year by the surgeons at Laparoscopic Associates of San Francisco. Doctors Cirangle, Jossart, and Feng’s bariatric surgeries achieve excellent long-term weight-loss for their morbidly obese patients as well as additional health benefits including:

· Diabetes cured in 77% of patients and resolved or improved in 86% of patients

· Hypertension (high blood pressure) cured in 62% of patients and resolved or improved in 78.5%

· Hyperlipidemia (high cholesterol and high triglycerides) improved in more than 70% of patients

· Obstructive sleep apnea cured in 86% of patients

· Improvement is seen in many other conditions, such as: arthritis, fibromyalgia, asthma, acid reflux and heart failure.
