Background: Despite the fact that childhood obesity has become an epidemic in the western world with lifestyle changes having a limited success in sustaining weight loss; algorithms that incorporate bariatric surgery for adolescent weight management programs are lacking (1). Data comparing the efficacy of different bariatric procedures among pediatric patients is sparse. The safety and efficacy of the laparoscopic sleeve gastrectomy (LSG) and the laparoscopic roux-en-y gastric bypass (LRYGB), in the pediatric population, have been independently demonstrated (2). When comparing LSG with LRYGB in the adult population, there is no significant difference in short or mid-term weight loss (3). The objective of this study was to determine whether one bariatric surgery was more effective at lowering short-term (at one follow-up) BMI than another.
Methods: We retrospectively analyzed our series of pediatric patients (range; 15 to 21 years) who underwent either a LSG or LRYGB between 2011-2016, and those who subsequently followed up in one year.
Results: A total of 63 patients followed up at one year after having one of the two bariatric procedures done. 56 underwent LSG, while 7 underwent LRYGB. The mean pre- and post-operative BMIs for those who underwent LSG were 46.212 ± 6.29 and 33.192 ± 6.066, respectively. The mean pre- and post-operative BMIs for those who underwent LRYGB were 46.124 ± 4.413 and 32.052 ± 6.955, respectively. A t-test was used to measure the difference between the post-operative BMIs and a p-value of 0.646 was discovered.
Conclusion: Much like the adult population, there was no clinical or statistically significant difference in post-operative BMIs when comparing LSG vs. LRYGB at one year follow up. LRYGB, amongst the adults, produced better long-term weight loss (3). Therefore, the long-term efficacy and morbidity between these two bariatric procedures still needs to be determined.
