Trending Weight Loss Patterns in Obese and Super Obese Adolescents: Does Laparoscopic Sleeve Gastrectomy Provide Equivalent Outcomes in both Groups?

Many factors, including preoperative weight, may determine final weight loss after bariatric surgery; however, their proportional contribution is unclear. To such end, we evaluated weight loss patterns among obese adolescents.
We evaluated 57 adolescents who underwent laparoscopic sleeve gastrectomy from 2011 to 2017. Data collection included demographics, anthropometrics, and comorbidities and was done over a 3-year follow-up period. Statistical analysis was performed using Student’s t test and repeated measures ANOVA.
In the morbidly obese (MO) group, 82% were female, while 52% were male in the super obese (SMO) group (P < 0.0059). While 13/34 patients in the obese group achieved > 60% percent excess body weight loss (%EBWL), only 3/23 super obese patients achieved > 60% EBWL (P = 0.0695). %EBWL at 1-year follow-up significantly differed between the obese and super obese groups, 61.7 ± 14.6% and 47.7 ± 14.9% respectively (P = 0.035). The average BMI in the obese group was 29.8 at 1 year and 41.3 in the super obese group. There was a significant difference in the rate of excess weight loss (%EBWL/month) between the two groups (P < 0.01). There was good comorbidity resolution (about 70%) in both groups after surgery.
Comorbidity resolution after sleeve gastrectomy is excellent in the adolescent population irrespective of initial BMI. Consideration should be given to earlier bariatric intervention in SMO adolescents to facilitate return to near normal BMI. Focus on education of referral sources, such as community pediatricians and family practitioners to facilitate early bariatric evaluation should be considered. Weight loss in postsurgical SMO patients should be carefully monitored and adjunctive interventions should be considered.
