Thirty-Day Outcomes of Bariatric Surgery in Adolescents: a First Look at the MBSAQIP Database

Introduction Bariatric surgery is the only effective treatment of severe obesity. The number of adolescents undergoing bariatric surgery is increasing. However, bariatric surgery in adolescents is controversial. Objective The purpose of this study is to evaluate the outcomes of bariatric surgery in adolescents based on the MBSAQIP database (Metabolic and Bariatric Surgery Accreditation and Quality Improvement Project). Methods We analyzed the 2015-2017 MBSAQIP database; patients <= 19 years of age were included in our analysis. Primary outcomes were 30-day serious adverse events (SAEs), organ space infection (OSI), re-intervention, and re-operation rates. Secondary outcomes included operation length, hospital stay, and re-admission rates. We conducted separate Mann-Whitney rank sums tests, chi-square, or Fisher's exact tests as appropriate, withp < .05 denoting statistical significance. Results A total of 1983 adolescent patients were included in our analysis. The average age and BMI were 18.1 and 47.5, respectively. Of adolescent patients, 21.7% underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) and 78.3% underwent laparoscopic sleeve gastrectomy (LSG). The 30-day SAE and readmission rates were significantly lower for LSG compared with LRYGB (2.9% and 2.6% vs 6.5% and 5.6%, respectively;p < 0.05). The 30-day reoperation rate was also lower for LSG compared with LRYGB albeit not significant (1.1% and vs 2.3%;p = 0.05). The 30-day intervention rate for LSG was significantly lower, however, compared with LRYGB (1.2% vs 3%;p < 0.05). Compared with adult patients, > 19 years old (n = 353,726), we found no difference in our outcomes. However, adolescents had significantly shorter operation length. Conclusion In adolescents, LSG had fewer SAE, re-intervention, and readmission rates compared with LRYGB. There was no difference in outcomes between adolescents and adults.
