Safety and effectiveness of Roux-en-Y gastric bypass in patients between the ages of 17 and 19.

Abstract

Bariatric surgery is becoming more appealing as an option in addressing adolescent obesity. Concerns that may be encountered status postbariatric surgery include complications and failure to lose weight. The aim of our study is to describe safety and effectiveness of laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients between the ages of 17 and 19. A retrospective chart review was completed on LRYGB patients between January 2005 and May 2012. Fifteen patients less than 20 years of age were included. One patient was lost to follow-up, and therefore, 14 patients under the age of 20 were matched to 14 patients greater than 20 years of age for gender (p > 0.99), preoperative body mass index (BMI) (p > 0.96), and follow-up interval (p > 0.80). Mean postoperative BMI at last follow-up did not show statistical difference between the two (p > 0.74). Mean percentage of excess weight loss (%EWL) in patients under the age of 20 was 43.1 ± 14.6, 70.5 ± 17.0, 69.8 ± 17.3, and 54.8 ± 8.5 % at postoperative 6, 12, 24, and 36 months, respectively. In patients over the age of 20, mean %EWL was 39.9 ± 12.6, 67.0 ± 18.6, 60.2 ± 11.3, and 56.2 ± 6.2 %. Both group of patients showed improvement/remission of their comorbid conditions. No statistical difference was present between the two groups in terms of weight loss and comorbidity resolution. Each group had a single patient that required a revision for weight regain. LRYGB in younger patients almost the age of 20 is both safe and effective when compared to matched adults in regard to weight loss, comorbid condition, and complications.
