Background

Bariatric surgery is safe and effective, however, in adolescents it remains controversial. The purpose of this study is to evaluate the outcomes of bariatric surgery in adolescents based on the MBSAQIP database

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 (SAE), 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, with p < .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. 21.7 % underwent LRYGB (Laparoscopic Roux en Y Gastric Bypass) and 78.3 % underwent LSG (Laparoscopic Sleeve Gastrectomy). The 30-days SAE and readmission rates were significantly lower for LSG compared to 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 to LRYGB albeit not significant (1.1% and vs 2.3%, p=0.05). The 30 day intervention within 30 days for LSG was significantly lower, however, compared to LRYGB (1.2% vs 3%, p<0.05). Compared to adult patients, >19 yo (n=353,726) we found no difference in our outcomes. However, adolescents had significantly shorter operation length.

Conclusions

In adolescents LSG had fewer SAE, reintervention and readmission rates compared to RYGB. There was no difference in outcomes between adolescents and adults.
