Why Surgery?Why Surgery? Diet and exercise are not effective
long term in the morbidly obese Surgery is an accepted and effective
approach Medical co-morbidities are
improved/resolved Surgical risk is acceptable vs. risk of
long-term obesity
NIH Consensus NIH Consensus Conference 1991Conference 1991
Surgery is an accepted and effective approach that provides consistent, permanent weight loss for morbidly obese patients
Surgery indicated in patients with: BMI of 40 or over BMI of 35-40 with significant co-
morbidity documented dietary attempts ineffective
Who Is a Surgical Who Is a Surgical Candidate?Candidate?
Meets NIH criteria No endocrine cause of obesity Acceptable operative risk Understands surgery and risks Absence of drug or alcohol problem No uncontrolled psychological conditions Consensus after bariatric team evaluation:

How Does the Roux-en-Y How Does the Roux-en-Y Work? Work?
Surgery factors: restriction of meal size “dumping syndrome” some malabsorption decreased appetite
Patient factors: calorie intake calorie expenditure
Results of Gastric Results of Gastric Bypass*Bypass*
Longest and most thorough follow-up
Significant and durable weight loss Control of adult onset diabetes
mellitus Control of hypertension Long term improvement in health
and physical functioning*Results achieved in most but not all cases. Degree of improvements vary by individual
Laparoscopic Adjustable Laparoscopic Adjustable Gastric BandingGastric Banding
Restrictive Good results in
Europe and Australia Inamed Lap Band™
FDA approved 6/01 40-55% EBW Loss
How does the Band How does the Band work?work?
Surgery Factors: Restriction of meal size Decreased appetite
Patient Factors: Decreased calorie intake Increased calorie expenditure
Advantages of Advantages of LaparoscopyLaparoscopy
Fewer wound complications/infection Decreased rate of incisional hernias Less pain and faster recovery Surgeon has better view of the
anatomy Quicker return to work/activities Shorter hospitalization
