Predictive Factors of Outcome After Gastric Banding : A Nationwide Survey on the Role of Center Activity and Patients' Behavior

Systematic studies of postoperative outcome of bariatric surgery provide information on the predictors of success. Surgeon's and institution experience and patient's behavior after surgery are key determinant of success or failure. Data on clinical trials generally reflect the experience o...

Description
Summary:Systematic studies of postoperative outcome of bariatric surgery provide information on the predictors of success. Surgeon's and institution experience and patient's behavior after surgery are key determinant of success or failure. Data on clinical trials generally reflect the experience of skilled obesity surgery centers. Little is known about the current practice at a nationwide level. The present study was realized in the frame of a national survey on medical and surgical practices conducted by the public health insurance system. The objective was to analyze systematically and prospectively the outcome of all bariatric surgery procedures consecutively performed in a given period, as registered by the French National Medical Insurance Service. This study at a nationwide level focused on predictive factors of success and analyzed how the experience of the centers relates to the patients' outcomes at 1 and 2 years after surgery. This study examined prospectively the 2-year predictors of success of all consecutive 1236 bariatric operations performed at a nationwide level. Most (87.3%) were laparoscopic adjustable gastric banding (LAGB), so that the non-LAGB were eliminated from the study. Data were collected independently by consultants of the French National Medical Insurance Service: characteristics of the patients, evolution of body mass index (BMI), physical activity and comorbidities, changes in behavior, complications, reoperations. Information was available on the activity of the surgical teams. Excess weight loss (EWL) >50% was considered a "success," and EWL
