RESUMO
Introduction In the Netherlands, bariatric surgery in adolescents is currently only allowed in the context of scientific research. Besides this, there was no clinical pathway for bariatric surgery in adolescents. In this paper, the development of a comprehensive clinical pathway for bariatric surgery in adolescents with severe obesity in the is described. Methods The clinical pathway for bariatric surgery in adolescents consists of an eligibility assessment as well as comprehensive peri- and postoperative care. Regarding the eligibility assessment, the adolescents need to be identified by their attending pediatricians and afterwards be evaluated by specialized pediatric obesity units. If the provided treatment is considered to be insufficiently effective, the adolescent will anonymously be evaluated by a national board. This is an additional diligence procedure specifically established for bariatric surgery in adolescents. The national board consists of independent experts regarding adolescent bariatric surgery, and evaluates whether the adolescents meet the criteria defined by the national professional associations. The final step is an assessment by a multidisciplinary team for adolescent bariatric surgery. The various disciplines (pediatrician, bariatric surgeon, psychologist, dietician) evaluate whether an adolescent is eligible for bariatric surgery. In this decision-making process, it is crucial to assess whether the adolescent is expected to adhere to postoperative behavioral changes and follow-up. When an adolescent is deemed eligible for bariatric surgery, he or she will receive preoperative counselling by a bariatric surgeon to decide on the type of bariatric procedure (Roux-en-Y gastric bypass or sleeve gastrectomy). Postoperative care consists of intensive guidance by the multidisciplinary team for adolescent bariatric surgery. In this guidance, several regular appointments are included and additional care will be provided based on the needs of the adolescent and his or her family. Furthermore, the multidisciplinary lifestyle intervention, in which the adolescents participated before bariatric surgery, continues in coordination with the multidisciplinary team for adolescent bariatric surgery, and this ensures long-term counselling and follow-up. Conclusion The implementation of bariatric surgery as an integral part of a comprehensive treatment for adolescents with severe obesity requires the development of a clinical pathway with a variety of disciplines.
RESUMO
Background & Aims: The long-term outcome of paediatric non-alcoholic fatty liver disease (NAFLD) has not been well established. Between 2008 and 2012, an unselected cohort of 133 children with severe obesity was screened for NAFLD. The aim of this study was to determine the 10-year natural history of NAFLD in this cohort. Methods: All 133 participants of the original study were approached. Proton magnetic resonance spectroscopy (1H-MRS) and the Enhanced Liver Fibrosis® (ELF) test were used to assess longitudinal changes in steatosis and fibrosis, respectively. Risk factors for disease progression were explored. Results: Fifty-one of the 133 participants (38%) from the original cohort were included. The mean follow-up time was 10.3 years (range 7-13 years), 65% were female and 92% had persistent obesity. The proportion of participants with steatosis remained unchanged (47%). Nine individuals developed steatosis and in nine individuals steatosis resolved. Predefined relevant individual changes in 1H-MRS were seen in 38% of the participants. The mean ELF test did not change significantly (8.70 ± 0.58 vs. 8.51 ± 0.71, p = 0.22). However, 16% had a relevant increase in ELF test and 6% of those with NAFLD developed advanced fibrosis at follow-up. Changes in steatosis correlated with changes in established metabolic risk factors, alanine aminotransferase, and bariatric surgery. A change in the ELF test was associated with a change in triglycerides. Conclusions: This 10-year follow-up study shows that one-third of the young adults who had childhood obesity develop steatosis and in one-third steatosis resolves. Six percent of those with NAFLD had developed advanced fibrosis at follow-up. These data underscore the importance of screening for NAFLD and monitoring for progression to advanced NAFLD in young people with obesity. Impact and implications: Childhood obesity accompanied by fat accumulation in the liver persists into young adulthood in the vast majority, and 6% develop serious liver injury. Worsening of metabolic disturbances increases the risk of liver injury.
