Bariatric Surgery

Bariatric Surgery
The mission of The Obesity Society’s Bariatric Surgery Section is to advance the science of bariatric surgery and the clinical management of the bariatric surgery patient utilizing a multidisciplinary approach.

Goals

  • Content development and organization of a “Bariatric Day” of Symposia for TOS 2011
  • Obesity Week 2013 Combined Symposia Development—the above stated goal is a preliminary step toward this longer-term project
  • Increased use of electronic resources such as: website bulletin board, list-serv, and links to our department's web-based journal club
  • Continue to build content of our newsletter with relevant information for our membership
  • Develop and distribute information regarding ongoing studies involving bariatric surgery with biannual updates
  • Develop an electronic bariatric surgery journal club

Oregon Health & Science University, Portland, OR

Samer G. Mattar, M.D, is Professor of Surgery, and he is the Chief of Bariatric Services at OHSU. Dr. Mattar's areas of interest include the optimization of outcomes of weight loss surgery, including the improvement, or cure, relevant comorbidities; bariatric surgery in adolescents; the treatment of patients with relapsed weight gain and high-risk bariatric patients. He also has an interest in the laparoscopic treatment of gastroesophageal reflux disease and other diseases of the foregut and the endoscopic diagnosis and treatment of foregut diseases. His areas of research include bariatric surgery outcomes, metabolic pathophysiology and surgical education. Dr. Mattar has held leadership positions at ASMBS and SAGES, and has been a member of TOS since 2003.


Shelby Sullivan, MD (Chair-Elect 2016-2017)   

Washington University School of Medicine, St. Louis, MO

Shelby Sullivan, M.D., is an Assistant Professor of Medicine at Washington University School of Medicine in the Division of Gastroenterology. She graduated with a degree in Nutrition from the University of Wisconsin Madison where she studied the effect of caloric restriction on intracellular insulin signaling in a primate model. She matriculated to Washington University School of Medicine for medical school and stayed through residency and fellowship to continue doing research in obesity and metabolism. Dr. Sullivan’s research focuses on both the pathophysiology of nonalcoholic fatty liver disease in patients with obesity and treating obesity with endoscopic bariatric therapy. Currently, she has a K23 award investigating the effects of an isocaloric diet high in high-fructose corn syrup in patients with obesity and nonalcoholic fatty liver disease using in vivo metabolic techniques including hyperinsulinemic euglycemic clamps and hepatic lipoprotein tracer studies. In addition, she is involved in a number of multi-center industry sponsored trials of endoscopic bariatric therapies for weight loss as either a site primary investigator or sub-investigator. She has been a member of TOS since 2010, and would like to help TOS and the Bariatric Surgery Section members bring endoscopic bariatric therapies into their practices as an option in the management of patients with obesity.


Valentina Ivezaj, PhD (Secretary/Treasurer 2016-2017)  

Yale School of Medicine, New Haven, CT

Dr. Ivezaj is an Associate Research Scientist in the Program for Obesity, Weight, and Eating Research (POWER) in the Department of Psychiatry at Yale University School of Medicine. Dr. Ivezaj’s major and longstanding clinical-research interests focus on psychosocial factors associated with bariatric surgery outcomes. Dr. Ivezaj also has a specific interest in alcohol and substance misuse problems in bariatric surgery patients. Currently, Dr. Ivezaj is playing a central role in several longitudinal studies of bariatric patients. First, she serves as project coordinator for a NIDDK-funded randomized controlled trial testing different behavioral treatments delivered following bariatric surgery aimed at improving eating behaviors and enhancing longer-term outcomes. Second, she serves as co-Investigator on a multi-site (Yale-NYU) study examining bariatric surgery outcomes in an ethnically/racially-diverse patient cohort. Third, she serves as co-Investigator on a multi-site (Yale/Indiana-St. Vincent Hospital) study examining the relationship between weight bias and bariatric surgery outcomes. Fourth, Dr. Ivezaj was recently funded, as PI, to prospectively examine obesity-related functional and psychosocial impairment before and after body contouring surgery among bariatric surgery patients. Finally, Dr. Ivezaj is also involved in collaborative research in community and clinical settings investigating binge eating, food addiction, and obesity in non-surgical populations.


Bec McDorman (Early Career Representative 2015-2017)
