Roux-en-Y Gastric Bypass
In the Roux-en-Y gastric bypass procedure, the stomach and small intestines are reconfigured to create a small stomach pouch. This induces weight loss by strictly limiting food intake and by allowing food to pass from the new pouch directly to the lower part of the small intestines and colon, bypassing most of the stomach and a portion of the intestine. Some malabsorption of vitamins and minerals results from this procedure, but appropriate supplements will provide compensation, allowing for good nutritional status. Weight loss tends to be very rapid with an average of 70 to 75 percent of excess weight lost within one year and at least 50 percent excess weight loss maintained at five years.
With laparoscopic sleeve gastrectomy, up to 85 percent of the stomach is removed, creating a small sleeve-shaped stomach. This reduces appetite and limits portion size dramatically. Since the small intestines are not altered, absorption of food and medications remains mostly unchanged. Weight loss rivals that of gastric bypass surgery, averaging 58 to 70 percent of excess body weight lost in about one year and at least 50 percent excess weight loss maintained at five years.
Laparoscopic Adjustable Gastric Band (LAGB)
The LAGB aids weight loss by limiting food consumption. The silicone band is laparoscopically placed around the stomach creating a "mini-stomach" just below the esophagus. No cutting or stapling of the stomach is required and no portion of the stomach or intestines is bypassed. The tightness of the band may be adjusted in an outpatient setting through an access port placed under the skin at the time of surgery. Weight loss tends to be more gradual, averaging 48 percent of excess body weight lost at three years.
Surgical Option Comparison
Stanford Health Care-ValleyCare's Weight Loss Surgery Program has been fully accredited by the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program. This designation is given to programs with a demonstrated track record of favorable outcomes in weight loss (bariatric) surgery. To earn this designation, all aspects of ValleyCare's weight loss surgical processes were closely examined and data on health outcomes collected.
Most insurance plans will cover Roux-en-Y gastric bypass, sleeve gastrectomy, or laparoscopic adjustable gastric band surgery if you meet their criteria for coverage. At ValleyCare, we accept almost all PPOs, some HMOs and Medicare.
Check with your insurance provider to:
- Ensure that surgery for weight loss is a covered benefit
- Understand what portion of the cost is to be covered, as well as your deductible or co-payment
- Learn if any specific criteria are required for approval
- Ascertain if ValleyCare is an allowed hospital within your plan
As an accredited Bariatric Surgery Center, we are included in most PPO plans. If you do not have coverage for weight loss surgery, you may want to consider our cash payment option.
Surgeons are specially trained in advanced laparoscopic procedures and are members of the American Society for Metabolic and Bariatric Surgery. In the medical evaluation, the surgeon will review your medical history and discuss the risks and benefits of the surgical options.
A nurse practitioner (NP) will help educate you about the surgery. The nurse is a valuable resource for information, pre- and post-surgery instructions, and after-care questions.
A registered dietitian (RD) oversees the dietary component of patient care. The dietitian will perform the dietary assessment, assist in developing a meal plan and behavior modification plan, and provide information and guidance on dietary concerns.
An exercise specialist will guide you on the activity portion of your weight loss plan if desired. You may choose to exercise at ValleyCare’s LifestyleRx, a wellness facility located in Livermore, where a fitness professional can assist you in proper techniques for strength building, flexibility and conditioning.
A Clinical psychologist assists in the evaluation process. The therapist will help you prepare for your post-surgery lifestyle. She can also help you in a private setting if you struggle with emotional eating or compulsive eating behaviors.
What to Expect After Weight Loss Surgery
At ValleyCare, we have been performing weight loss surgery since 2000. Almost all surgeries are performed laparoscopically, which means that surgical instruments are inserted into the abdomen through tiny incisions. This allows for minimal blood loss and more rapid recovery than traditional, open surgery. Most patients stay in the hospital only one or two nights and are back to work within a few weeks.
Weight loss varies depending upon which procedure is chosen. Most gastric bypass patients will lose approximately 70 to 75 percent of their excess body weight within one year. In the same time frame, sleeve gastrectomy patients typically lose 58 to 70 percent of excess weight. LAGB patients will likely lose weight more gradually and less weight overall, but weight loss from all surgeries will improve your health and quality of life.
Many health problems are significantly improved or resolved after weight loss surgery. Most people who have type 2 diabetes, sleep apnea, hypertension, reflux or heartburn (GERD), high cholesterol or joint pain will find they need less or no treatment with their post-surgery weight loss.
With weight loss and improved health, better quality of life usually follows. Most people enjoy tremendous improvement in their personal and professional lives.
