The Impact of Bariatric Surgery on Health Care Costs
Date/Time: 8:45 a.m. Wednesday
Lead Author: Anita P. Courcoulas, MD, University of Pittsburgh Medical Center
Key finding: Bariatric surgery reduces health care costs over time, especially those related to medication usage.

Bariatric Surgery in Adolescents: Analysis of 309 Cases
Date/Time: 9 a.m. Wednesday
Lead Author: Esteban Varela, MD, MPH, VA North Texas Health Care System and University of Texas Southwestern

Preoperative Weight Gain Does Not Predict Failure of Weight Loss or Co-morbidity Resolution of Gastric Bypass for Morbid Obesity
Date/Time:
10:30 a.m. Wednesday
Lead Author: Michael C. Harnisch, MD, Duke University
Key finding: Gastric bypass surgery can be performed safely with improvements in co-morbidity and extended weight loss regardless of preoperative weight gain or loss.

Presurgery Psychiatric Disorders are Associated with Smaller Reductions in BMI at 6 Months After Gastric Bypass
Date/Time:
10:45 a.m. Wednesday
