AI Article Synopsis

  • Approximately 100 obese adolescents in France undergo bariatric procedures annually, with this study focusing on those who had Roux-en-Y gastric bypass (RYGB) since previous data primarily covered other procedures like LAGB and SG.
  • The study analyzed 26 adolescents aged 13-19 who underwent RYGB, observing a significant BMI decrease from a mean of 52.0 kg/m² to 35.7 kg/m² after two years, along with improvements in several comorbidities.
  • Adverse events were generally low, with few complications noted, and the outcomes were comparable to those seen in adult patients undergoing the same procedure.

Article Abstract

Introduction: In France, approximately 100 obese adolescents undergo a bariatric procedure every year. To date, only data from laparoscopic adjustable gastric banding (LAGB) or sleeve gastrectomy (SG) have been published. Our objective was to report the outcomes of a series of French obese adolescents who underwent a Roux-en-Y gastric bypass (RYGB).

Methods: We included all obese adolescents aged 13-19 years who underwent RYGB in our department from 2008 with at least 2 years of follow-up after surgery. We analyzed the course of the anthropometric data, comorbidities, and subsequent adverse events.

Results: Starting in September 2008, out of 93 obese adolescents who requested bariatric surgery, 39 (35%) underwent a bariatric procedure. From these adolescents, 2-year follow-up data were available for 26 patients who had a RYGB. At the time of surgery, the mean patient age was 17.4 years (standard deviation [SD]=1.4) and the body mass index (BMI) was 52.0 kg/m² (SD=7.8). One patient was lost to follow-up. At 2 years after surgery,  the mean BMI was 35.7 kg/m² (SD=9.4) with a mean decrease in BMI of 31.9% (SD=11.6). Comorbidities improved for most of the patients: high blood pressure (2/2) and pseudotumor cerebri (1/1) were cured after surgery, and dyslipidemia improved globally. The complications observed were anemia, abdominal pain requiring celioscopy (n = 2), and oxalic nephrolithiasis.

Conclusion: Only one third of the obese adolescents requesting bariatric surgery were operated on. Our series including exclusively obese adolescents who underwent an RYGB presents the results of this technique on weight loss and comorbidities; mechanical and nutritional complications remain uncommon. These results are similar to those obtained in studies of adult patients.

Background/aims: To evaluate the associations between pediatric fatty liver severity, bioelectrical impedance analysis (BIA), and magnetic resonance imaging parameters, including total psoas muscle surface area (tPMSA) and paraspinal muscle fat (PMF).

Methods: Children and adolescents who underwent BIA and liver magnetic resonance imaging between September 2022 and November 2023 were included. Linear regression analyses identified predictors of liver proton density fat fraction (PDFF) including BIA parameters, tPMSA, and PMF.
