Background Bariatric surgery is regarded as the most effective treatment of morbid obesity in adults. Referral patterns for bariatric surgery in adults differ among general practitioners (GPs), partially due to restricted knowledge of the available treatment options. Reluctance in referral might be present even stronger in the treatment of morbidly obese children.Objectives The aim of this study was to investigate the current practice of GPs regarding treatment of paediatric morbid obesity and their attitudes towards the emergent phenomenon of paediatric weight loss surgery. Methods All GPs enlisted in the local registries of two medical centres were invited for a 15-question anonymous online survey. Results Among 534 invited GPs, 184 (34.5%) completed the survey. Only 102 (55.4%) reported providing or referring morbidly obese children for combined lifestyle interventions. A majority (n = 175, 95.1%) estimated that conservative treatment is effective in a maximum of 50% of children. Although 123 (66.8%) expect that bariatric surgery may be effective in therapy-resistant morbid obesity, only 76 (41.3%) would consider referral for surgery. Important reasons for reluctance were uncertainty about long-term efficacy and safety. The opinion that surgery is only treatment of symptoms and therefore not appropriate was significantly more prevalent amongst GPs who would not refer (58.3% vs. 27.6%, p \ 0.001). Conclusion There is a potential for undertreatment of morbidly obese adolescents, due to suboptimal knowledge regarding guidelines and bariatric surgery, as well as negative attitudes towards surgery. This should be addressed by improving communication between surgeons and GPs and providing educational resources on bariatric surgery.
BackgroundObesity in children and adolescents is an increasing problem associated with multiple co-morbidities including metabolic and endocrine changes, cardiovascular abnormalities, and impaired quality of life. Combined lifestyle interventions are the current standard treatment for severe obesity in children. However, the medium- and long-term results of these interventions are relatively poor. Bariatric surgery shows substantial weight loss and health improvement in adults and retrospective studies in adolescents show similar outcomes. However, well-designed prospective studies in this young age group are rare. Our objectives are to determine whether combining surgery with lifestyle interventions in severely obese adolescents leads to a significant additional weight reduction compared to lifestyle interventions solely, and to assess its effect on obesity-associated co-morbidities in a prospective randomized controlled setting.MethodsPatients aged 14–16 years with sex- and age-adjusted BMI > 40 kg/m2 (or > 35 kg/m2 with comorbidity) and failure to achieve weight reduction > 5% during at least one year of combined lifestyle interventions are included in this trial. Randomization determines whether laparoscopic adjustable gastric banding will be added to combined lifestyle intervention throughout the trial period. Sixty children will be included in this trial. Follow-up visits are planned at 6 months, 1,2 and 3 years. Primary endpoints are percentage of total weight loss, and change of BMI. Secondary endpoints include body composition, pubertal development, metabolic and endocrine changes, inflammatory status, cardiovascular abnormalities, non-alcoholic steatohepatitis, quality of life and changes in behaviour.DiscussionThis randomized controlled trial is designed to provide important information about the safety and efficacy of laparoscopic adjustable gastric banding treatment in severely obese adolescents with unsuccessful combined lifestyle interventions. The reversibility of this surgical procedure forms a strong argument to decide for gastric banding over other surgical procedures, since bariatric surgery in adolescents is still in its infancy.Trial registrationThe BASIC trial is registered in the register of ClinicalTrials.gov since July 2010, Identifier: NCT01172899Electronic supplementary materialThe online version of this article (10.1186/s12887-019-1395-9) contains supplementary material, which is available to authorized users.
Introduction Bariatric surgery is performed at increasing rate in severely obese adolescents who do not respond to conservative treatment. In the United States, this treatment is generally accepted, yet in Europe, surgeons are more reluctant because of concerns regarding safety and (long-term) efficacy. We evaluated in which (European) countries bariatric surgery is allowed and performed, and the opinion of the members of the European Paediatric Surgeons' Association (EUPSA) regarding bariatric surgery in adolescents. Materials and Methods Information was obtained with an online questionnaire sent to all EUPSA members. Results A total of 108 pediatric surgeons (PSs) from 33 countries (of which 25 European) completed the survey. Sixty-two PSs (57.4%) from 22 countries stated that bariatric surgery in adolescents was allowed in their country. In only 14 countries, the costs were (partially) covered by health care insurances. Overall, 65.7% of the surgeons (n = 71) believed bariatric surgery may offer a valuable contribution to obtain substantial long-term weight loss in severely obese adolescents. Fifty-one (47.2%) reported that these procedures should be performed by a combination of a bariatric and a PS, while 20 (18.5%) and 16 (14.8%) preferred that these procedures should be performed solely by a PS or bariatric surgeon, respectively. Conclusion Although allowed in most European countries, bariatric surgery in adolescents is only practiced on a small scale, and the treatment is often excluded from regular health care reimbursement. The majority of PSs acknowledge the value of bariatric surgery, which should be performed by a combination of PS and bariatric surgeon.
Background: Vagus nerve injury (VNI) is a feared complication of antireflux surgery (ARS). The impact of VNI on the functional outcomes of ARS has not yet been evaluated systematically. The aim of this review was to evaluate the impact of VNI on functional and clinical outcome of ARS. Methods: A systematic search was performed until March 2015, using the following online databases: MEDLINE, Embase and the Cochrane Register of Controlled Clinical Trials. Eight studies remained available for assessment. Articles were divided into 2 groups: (a) one with unintended, accidental VNI and (b) one group comparing ARS with and without intended vagotomy. Results: The prevalence of unintended, accidental VNI ranged from 10 to 42% after ARS. No clear differences were seen in outcome for reflux control between the VNI and vagus nerve intact group. A higher prevalence of diarrhea, nausea and vomiting was observed in the VNI group. Conclusion: VNI is a feared but neglected complication of ARS. Larger prospective studies that objectively assess vagus nerve integrity before and after ARS are needed.
Left ventricular hypertrophy (LVH) is independently associated with a higher risk of cardiovascular morbidity and mortality in adults. Adiposity is a risk factor for LVH, independent of blood pressure. Potential causes of this nonhemodynamic pathogenesis identified in adults include adverse body fat distribution, insulin resistance, dyslipidemia, and obstructive sleep apnea syndrome (OSA). In severely obese adolescents, the determinants of obesity-induced changes in left ventricular structure are poorly characterized. Cardiac ultrasonographic, demographic, anthropometric, and comorbidity-related data were prospectively collected in adolescents with severe obesity refractory to conservative treatment who presented for surgical therapy. Differences between adolescents with LVH and without LVH were evaluated using independent samples t, chi-square, or Fisher’s exact test. Multivariable linear regression analysis was performed to evaluate associations with left ventricular structural changes, corrected for body mass index (BMI) z score. Forty-three patients entered analysis, of whom 24 (55.8%) showed LVH. The most common geometrical change was eccentric LVH (eLVH), occurring in 21 subjects (48.8%). Demographic and anthropometric variables did not differ between patients with and without LVH. Independent of BMI z score, left ventricular mass index was significantly associated with apnea–hypopnea index (AHI) (regression parameter B = 0.8; 95% CI 0.3 to 1.2). Interventricular septum thickness (IVST) was significantly associated with HOMA-IR values (B = 0.1; 95% CI 0.04 to 0.2), HDL-cholesterol (B = − 1.2; 95% CI − 2.2 to 0.1), and triglyceride levels (B = 0.5; 95% CI 0.001 to 0.9). LVH, especially eLVH, is highly prevalent amongst severely obese adolescents. Adverse changes in cardiac structure, increased IVST in particular, are independently associated with several nonhemodynamic comorbidities that are common in this population, namely OSA, insulin resistance, and dyslipidemia.
Background Recent studies have indicated that bariatric surgery is effective for the treatment of youth with severe obesity. The attitudes of pediatricians, parents, and adolescents regarding this topic remain unclear. Therefore, the aim of this study was to assess the current thoughts and beliefs of Dutch pediatricians, parents, and adolescents regarding bariatric surgery in youth. Methods An online survey containing twenty questions on bariatric surgery in youth was distributed to pediatricians of the Dutch Society of Pediatrics. Parents and adolescents who participated in an interdisciplinary care program for overweight, obesity, and severe obesity filled out an online survey of twelve questions. Results One hundred and twenty-one pediatricians, 49 parents, and 19 adolescents completed the surveys. Seventy-two pediatricians (59.5%) considered bariatric surgery to be an effective treatment for youth with severe obesity when conventional treatment fails, and intend to refer patients for bariatric surgery. The most frequently suggested conditions for bariatric surgery were a minimum age of 16 years (n = 59, 48.7%), a BMI threshold of 40 kg/m2 (n = 51, 42.2%), and a minimum Tanner stage of IV (n = 59, 48.8%). Thirty parents (61.2%) and fourteen adolescents (73.7%) responded that bariatric surgery should become available for youth with severe obesity. Conclusion Dutch pediatricians, parents, and adolescents increasingly accept bariatric surgery as a treatment modality in youth with severe obesity who do not respond successfully to lifestyle intervention. Whether pediatricians will actually refer youth for bariatric surgery remains to be seen when this treatment option will be implemented in the Netherlands. Graphical abstract
