The objective of this study is to update evidence-based best practice guidelines for pediatric/adolescent weight loss surgery (WLS). We performed a systematic search of English-language literature on WLS and pediatric, adolescent, gastric bypass, laparoscopic gastric banding, and extreme obesity published between April 2004 and May 2007 in PubMed, MEDLINE, and the Cochrane Library. Keywords were used to narrow the search for a selective review of abstracts, retrieval of full articles, and grading of evidence according to systems used in established evidence-based models. In light of evidence on the natural history of obesity and on outcomes of WLS in adolescents, guidelines for surgical treatment of obesity in this age group need to be updated. We recommend modification of selection criteria to include adolescents with BMI ≥ 35 and specific obesity-related comorbidities for which there is clear evidence of important short-term morbidity (i.e., type 2 diabetes, severe steatohepatitis, pseudotumor cerebri, and moderate-to-severe obstructive sleep apnea). In addition, WLS should be considered for adolescents with extreme obesity (BMI ≥ 40) and other comorbidities associated with long-term risks. We identified >1,085 papers; 186 of the most relevant were reviewed in detail. Regular updates of evidence-based recommendations for best practices in pediatric/adolescent WLS are required to address advances in technology and the growing evidence base in pediatric WLS. Key considerations in patient safety include carefully designed criteria for patient selection, multidisciplinary evaluation, choice of appropriate procedure, thorough screening and management of comorbidities, optimization of long-term compliance, and age-appropriate fully informed consent.
Gastrointestinal weight-loss surgery (GIWLS) is currently the most effective treatment for severe obesity, with Roux-en-Y gastric bypass (RYGB) among the best of the available surgical options. Despite its widespread clinical use, the mechanisms by which RYGB induces its profound weight loss remain largely unknown. This procedure effects weight loss by altering the physiology of weight regulation and eating behavior rather than by simple mechanical restriction and/or malabsorption as previously thought. To study how RYGB affects the physiology of energy balance, we developed a rat model of this procedure. In this report, we demonstrate that RYGB in diet-induced obese (DIO) rats induces a 25% weight loss, prolongs mean survival by 45%, and normalizes glucose homeostasis and lipid metabolism. RYGB induced a 19% increase in total and a 31% increase in resting energy expenditure (REE). These effects, along with a 17% decrease in food intake and a 4% decrease in nutrient absorption account for the normalization of body weight after this procedure. These effects indicate that surgery acts by altering the physiology of weight regulation and help to explain the effectiveness of RYGB in comparison to restrictive dieting and other forms of dietary and pharmacological therapies for obesity. The clinical effectiveness of RYGB and its physiological effects on body weight regulation and energy expenditure (EE) suggest that this operation provides a unique opportunity to explore the mechanisms of energy homeostasis and to identify novel therapies for obesity and related metabolic diseases.
Sibutramine added to a behavior therapy program reduced BMI and body weight more than placebo and improved the profile of several metabolic risk factors in obese adolescents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
