Risk of Death and Obesity D E A T H BMI
Treatment Options • Diets • Exercise • Behavior Modification • Medication • Surgery
Diets Don’t Work ! • Almost anyone can lose weight dieting • Almost no one can maintain long term weight loss • 97% of patients 100 pounds or more overweight regain lost weight within 2 years • Often gain more than was lost
Exercise • Very important as part of any weight loss program • Regular exercise causes more weight loss and keeps it off longer • Length of time is more important than intensity • Rarely enough as treatment alone
Medications • Cause only modest weight loss 10-15% • Need to be taken indefinitely • Often cause side effects • Expensive and often not covered by insurance • Only work well in combination with diet and exercise
Surgery • There are 2 safe and effective procedures commonly used in the US • Vertical Banded Gastroplasty • Gastric Bypass • 20 year history and follow up • Only proven long term effective treatment • Patients should have failed other treatments
Vertical Banded Gastroplasty • VBG commonly known as Stomach Stapling • Small stomach pouch • Staples partition stomach • Plastic band controls outlet to rest of stomach
Vertical Banded Gastroplasty • Advantages • Simple to perform • Bottom of stomach and duodenum can be easily examined • Low incidence of leaks • Normal absorption of nutrients • ? lower risk of bowel obstruction
Problems with VBG • Staple line can pull through (break) • Band too tight for some causes vomiting • Not adjustable • Infection or erosion of band • Can lead to poor dietary habits • Failure in 25-50% of patients • Has fallen out of favor in US
Gastric Bypass • Small stomach pouch made from top of stomach • Pouch empties directly to intestine • Food and enzymes meet lower down in the intestine • No plastic ring
Gastric Bypass Advantages • No plastic ring • Greater weight loss • Causes avoidance of sweets and fats • Most foods well tolerated • Low failure rate • Little weight regain
Problems with Gastric Bypass • Higher rate of complications • 1/2 - 1% death rate • Vitamins and minerals poorly absorbed • Laparoscopy may increase complications • Difficult to reverse
Lap-Band System • System Components • Silastic band • Integrated bladder • Self locking buckle • Tubing • Port
Lap Band Around the World • Most common operation for obesity in Europe, Australia and South America. • Over 50,000 implanted worldwide in past 9 years • Extremely safe with good weight loss • Recently FDA approval in the US
Diet after Operation • Fluids • Pureed foods • Soft food • Regular food • Meats, fresh breads and white rice come last and may not be well tolerated except in small amounts and well chewed
Office Visits • 2 weeks after surgery • 6 weeks after surgery • may have first band adjustment • Monthly for first year • band adjustments as indicated • Quarterly in second year • Yearly for life
Education Nurse understand procedure care after operation Nutritionist diet changes healthy balanced food choices Surgery Commitment follow up follow the rules Components for Success
Weight Loss • More Gradual than other operations • Continues longer up to 2 years • 1/3-2/3 of excess weight • Depends on following rules • No Sweets • No Snacking • No liquids with calories • A Tool not a Miracle
Complications • Band Slippage 3-5% • Band Erosion 1-3% • Tubing Leak 2-3% • Port Infection 1-2% • Stomach Perforation <1% • Esophageal Dilation ? • Death <0.1% (less than 1/1000)
Summary • Obesity is a significant health problem • Non-surgical treatment is ineffective long term • Gastric Bypass is currently most common in US • Lap-Band most common in rest of World • Lap-Band is safer than Gastric Bypass but may offer less weight loss on average • Commitment to long term dietary change is key to success with Lap-Band
