Background

The impact severe obesity has on self-esteem, particularly in the early adolescent period, needs to be seriously deliberated as it leads to risky behaviour and can significantly affect the quality of life. Objective: This study aims to evaluate the efficacy of treating severe obesity and its co-morbidities among adolescents.

Methods

A retrospective study conducted on adolescents with severe obesity who underwent BMS from 2010 to 2017 at a single centre were collected, reviewed and analysed.

Results

A total of 95 patients underwent one of three BMS procedures. Forty-three patients (45%) had a sleeve gastrectomy (SG), 24 (25%) a one-anastomosis gastric bypass (OAGB), and 28 (30%) a Roux-en-Y gastric bypass (RYGB). Fifty-six (59%) were males. The average age was 15.7±2.6 years, and the average BMI was 40.1±6.6 kg/m2. Follow-up ranged from 6 months to 6 years. There were no complications and no mortality in this series. At one year the percent excess weight loss (%EWL) and percent total weight loss (%TWL) was 69.3% and 25.2%, respectively, and these decreased to (54.4% and 19.2%) at six years. There were resolutions of sleep apnea (SA, 40%), type 2 diabetes (T2D, 50%), and hypertension (HTN, 60%). Nutritional deficiencies observed in some patients at one year, but values normalised with nutrient supplements.

Conclusions

Bariatric/metabolic surgery is an effective, safe treatment for severe adolescent obesity in short- to medium-term. Further studies are required to investigate the long-term effects with comparisons of different bariatric/metabolic procedures.
