What Is Obesity?

A life-long, progressive, life-threatening,
costly, genetically-related, multi-factorial
disease of excess fat storage with
multiple co-morbidities
ASBS



Clinically severe obesity at which point
serious medical conditions occur as a direct
result of the obesity
Defined as >200% of ideal weight, >100 lb

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 Conference 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 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:
 Surgeon/Dietician/Psychologist/Consultant
Dedicated to life-style change and follow-up
Roux-en-Y Gastric Bypass





Combination
Most frequently
performed bariatric
procedure in the US
First done in 1967
Laparoscopically
since 1993
60-70% EBW 14yr
follow-up
ASBS
How Does the Roux-en-Y Work?

Surgery factors:
restriction of meal size
 “dumping syndrome”
 some malabsorption
 decreased appetite


Patient factors:
calorie intake
 calorie expenditure

Results of Gastric 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 Gastric
Banding




Restrictive
Good results in Europe
and Australia
Inamed Lap Band™
FDA approved 6/01
40-55% EBW Loss
How does the Band work?
Surgery Factors:
 Restriction of meal size
 Decreased appetite
Patient Factors:
 Decreased calorie intake
 Increased calorie expenditure
Advantages of Laparoscopy






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

Open Bypass
4-7 days
Gastric Band
overnight stay
Swallow study performed day 1-3
Liquid diet started
