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.
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
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 various surgical options. The risks and benefits will be fully explained.
A registered nurse will help educate you about the surgical options and will actively support you as you prepare for surgery. The nurse is a valuable resource for procedure information, pre- and post-surgery instructions and after-care questions.
A registered dietitian oversees the dietary component of patient care. The dietitian will perform the dietary assessment in the initial evaluation, assist in developing a behavior modification plan, provide information and guidance on post-surgery dietary concerns and help you plan for long-term weight management.
A psychologist (or psychotherapist) assists in the evaluation process. The therapist is available to provide direction and support for the emotional component of behavior change and to help you prepare for the lifestyle changes you will be making.
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.
