107 active trials for Obesity, Morbid

Bariatric Surgery in Children.

Rationale: In the Western world overweight and obesity is an increasing problem both in adults and in children. In youth, it is associated with early death and a number of co-morbidities including metabolic and endocrine changes, increased inflammatory status, cardiovascular abnormalities, nonalcoholic fatty liver disease, and impaired quality of life. The standard treatment for morbid obesity in children is by combined life style interventions. However, the medium and long term effects of dietetic interventions, behaviour therapy and medication is relatively poor. In adults bariatric surgery shows good results with up to 30% weight reduction in 3 years. The preliminary results in youth are similar, but surgery in this age group is relatively uncommon. In the Netherlands surgery in this age group is only allowed in clinical trials, until the benefits and risks have been established. (National Health Authorities) Objective: To determine if surgery gives a superior weight and body mass index (BMI) reduction than combined life style interventions in adolescents with morbid obesity and to assess its effect on obesity associated co-morbidity. Study design: Prospective randomised interventional study. Study population: Morbidly obese children, aged 14 - 16 years, with sex and age adjusted BMI >40 kg/m2 or >35 kg/m2 with co-morbidity. Intervention: Bariatric surgery by laparoscopic adjustable gastric band (LAGB) or combined life style interventions Main study parameters/endpoints: Primary endpoints: weight loss, loss of excess weight, loss of excess BMI. Secondary endpoints: Body composition, pubertal development, metabolic and endocrine changes, inflammatory status, cardiovascular abnormalities, non-alcoholic steatohepatitis, brain development, quality of life, and behaviour changes. The potential complications of surgery are monitored.

Single-anastomosis Duodeno Ileal Bypass (SADI) Versus Roux-en-Y Gastric Bypass

Obesity is a major public health problem worldwide. Bariatric surgery has proved to be the most effective treatment of morbid obesity in terms of weight reduction and remission of co-morbid conditions during long-term follow-up. Nowadays, France is ranked 3rd in terms of bariatric surgeries performed per year. Since the laparoscopic Roux-en-Y gastric bypass (RYGB) was described in 1977, this restrictive and malabsorptive procedure has become a gold standard for morbid obesity with an average Excess Weight Loss % (EWL%) of 72% at 2 years, and a strong metabolic effect, especially with regard to type 2 diabetes remission. Nevertheless, failures are observed (up to 20%), particularly in super obese patients, which are then difficult to manage. In this population, biliopancreatic diversion with duodenal switch (BPD-DS) is indicated due to its stronger weight loss and metabolic effect, but is still little performed worldwide because of its higher morbidity, surgical complexity and risk of malnutrition. A novel technique combining the physiological advantages of pylorus preservation and the technical benefits of single-loop reconstruction was introduced in 2007 by Sanchez-Pernaute, who described the single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) as an evolution of the BPD-DS. With a 2.5-meter common channel, SADI-S seems to offer good results for the treatment of both morbid obesity and its metabolic complications, with an EWL% of up to 95% at 2 years and potentially less nutritional consequences. To date, there is only one Spanish randomized trial comparing SADI-S to BPD-DS, whereas BPD-DS represents less than 1% of bariatric procedures in France and is only allowed in super obese patients. Thus only preliminary data of poor scientific value exists. Nevertheless, facing very encouraging short-term outcomes, there is a real need for a prospective trial comparing SADI-S to a standard bariatric procedure. The aim of the investigator's study is to assess weight loss efficiency and the morbi-mortality of the SADI-S in comparison to a standard (RYGB), in order to validate this procedure among bariatric techniques HYPOTHESIS SADI-S is superior to the standard RYGB for weight loss, increasing the EWL% by 10% (82% vs 72%, respectively) at 2 years.
