pregnancies and impaired glucose tolerance in 13. Cesarean
section was performed in 17 cases. Two women were operated
during pregnancy (16.3 weeks) due to band slippage, and the
band was removed laparoscopically.
Conclusions: LAGB is safe and well tolerated during pregnancy.
The option of band adjustment permits optimal maternal
medical control.

LAPAROSCOPIC ROUX-EN-Y GASTRIC BYPASS IN THE ELDER-
LY POPULATION., Carlos A Schiavon MD, Jose S Pinheiro MD,
Jose Correa MD,Ricardo Cohen MD, Center for the Surgical
Treatemnt of Morbid Obesity, Hospital Sao Camilo, Sao Paulo,
Brazil
Introduction: Obesity is a devastating disease and is associated
with a series of life-threatening complications. If patients
over 60 years of age are submitted to large and aggressive
procedures, such as coronary bypass surgery and hip joint
replacement surgery, why shouldn?t gastric bypass be performed
for the treatment of morbid obesity in this group of
patients?
Methods: We reviewed the data of 108 patients who were over
60 years of age and underwent laparoscopic Roux-en-Y gastric
bypass in our Institution (9.8% of our patients).
Results: Most were women (71 patients) and mean BMI was 44
(38 to 55). Mean age was 66 (60 to 76). Preoperative comorbities
were as follows: artropathy was present in 76 patients,
hypertension in 73 patients, diabetes in 66, cardiopathy in 54,
lipid disorders in 35, GERD in 19, and sleep apnea in 12.There
were no intraoperative complications. Mean hospital stay was
36 hours. One patient presented with postoperative pneumonia.
There were no postoperative leaks in this group of
patients. We had a 92.6% follow-up after 48 months in this
group of patients, in contrast to a 68.8% follow-up in our
younger patients. EWL was 71% at 12 months, 69% at 24
months, and 67% at 48 months. Hypertension was cured in 46
(63%) patients and 24 (32%) presented with easier controlled
disease. 51 (77%) diabetic patients were cured and 6 (9%)
decreased medication dosage. Lipid disorders were cured in
33 (94%) patients. All patients with cardiopathy presented significant
improvement in their disease. GERD and sleep apnea
were cured in all patients. 87 (81%) patients practice physical
activities regularly.
Conclusions: Patients over 60 years old benefit from laparoscopic
gastric bypass with high resolution of comorbidities
and good long-term weight loss. Patients are extremely adherent
to treatment.

ETHNIC DIFFERENCES IN WEIGHT LOSS SUCCESS FOLLOW-
ING ROUX-EN-Y GASTRIC BYPASS, Robert T Marema MD,
Nadege Francois BS,Cynthia K Buffington PhD, U.S. Bariatric
Introduction. The incidence of obesity among African
American (AA) females is higher than for AA males or other
ethnicities, and AA females are more resistant to diet-induced
weight loss. In the present study, we examined the effects of
Roux-en-Y gastric bypass (RYGBP) on the postoperative
weight loss of AA vs. Caucasian females, along with possible
predictors of weight loss differences, i.e. eating abnormalities,
psychosocial status.
Methods. The study population included 184 study participants
with the following measurements obtained prior to and one
year after RYGBP: 1) total body weight, 2) % excess weight
loss (EWL), 3) fat and fat-free mass (bioelectric impedance), 5)
psychosocial status, i.e. depression (Beck Depression
Inventory-II), Quality of Life (Moorehead-Ardelt), and 5) aberrant
eating behavior, i.e. carbohydrate craving, food addiction,
eating control, binge eating, and emotional eating.
Results. The data show one year postoperative that % EWL of
the AA females was significantly (p0.05) differences
between AA and Caucasian females with regard to any of the
measures of eating behavior. Levels of depression and quality
of life scores also did not significantly differ (p>0.05).
Conclusion. There are ethnic differences in the efficacy of the
RYGBP procedure among females one year postoperative. The
reduced surgical weight loss of AA females is significantly
associated with changes in fat mass but not eating behavior or
psychosocial issues.

PREDICTORS OF SUCCESS AFTER LAPAROSCOPIC GASTRIC
BYPASS; A MULTIVARIANT ANALYSIS OF SOCIOECONOMIC
FACTORS, Rami E Lutfi MD, Alfonso Torquati MD,NiKhilesh
Sekhar MD,William O Richards MD, Vanderbilt University
Laparoscopic roux-en-y gastric bypass (LGB) has proven efficacy
in causing significant and durable weight loss, however
there have been no studies looking at the value of patient
demographics in terms of predicting postoperative weight
loss. Aim: to identify independent predictors of successful
weight loss after LGB. Methods: Socioeconomic demographics
were prospectively collected on patients presenting for LGB.
Primary end-point was % of excess weight loss (EWL) at 1-yr
follow up. EWL was plotted in a normal histogram; insufficient
weight loss was defined as EWL
