NEW ORLEANS — Pediatric patients with severe obesity who underwent bariatric surgery between 2015 and 2017 had low rates of readmission, reoperation and complications, regardless of age or BMI, according to study findings presented at the AAP National Conference & Exhibition.
Researchers also noted that more pediatric and adolescent patients who underwent bariatric surgery during the study period opted for sleeve gastrectomy vs. Roux-en-Y gastric bypass.
Although the rate of pediatric obesity has tripled over the course of 3 decades and recent evidence has demonstrated the efficacy of bariatric surgery for reducing comorbidities and mortality and improving quality of life, less than 1% of children with severe obesity undergo the procedure, according to Robert Swendiman, MD, MPP, a general surgery resident in the University of Pennsylvania Health System, and colleagues.
“Choosing weight loss surgery is a life-altering commitment and can take years of planning. It may not be the best option for every patient,” Swendiman told Infectious Diseases in Children. “But if more adolescents undergo surgery, we need to be sure it is a safe option. Our study helps demonstrate that the surgery itself should be considered safe — even in younger patients — with low morbidity.”
The researchers conducted a prospective study that included data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program Participant Use File. They included patients aged 10 to 19 years who underwent laparoscopic or robotic Roux-en-Y gastric bypass or sleeve gastrectomy (n = 3,705).
The patients had a mean BMI of 47.4 kg/m2. Before surgery, the most common comorbidities included hypertension (33.8%), obstructive sleep apnea (16.1%), gastroesophageal reflux disease (12.9%) and diabetes (11.8%).
Readmission within 30 days of surgery occurred for 2.5% of patients (n = 128), and only 1% (n = 38) needed a second operation. Swendiman and colleagues wrote that the overall complication rate was 1.4% (n = 51).
The researchers noted that no patients with BMIs between 30 and 34.9kg/m2 required reoperation or reported complications. Furthermore, no deaths occurred during the study period.
Most surgeries performed between 2015 and 2017 (80.2%) were sleeve gastrectomies, whereas only 19.8% of patients opted for Roux-en-Y gastric bypass. According to the Swendiman and colleagues, the rate of sleeve gastrectomies increased significantly during the study period, from 73.9% in 2015 to 84.3% in 2017 (P < .001).
The researchers identified a higher rate of readmission when patients underwent Roux-en-Y compared with sleeve gastrectomy (OR = 1.62; 95% CI, 1.06-2.48). Patients who underwent Roux-en-Y also had a higher rate of complications (OR = 2.49; 95% CI, 1.34-4.64).
“Our study found that the odds for experiencing an intra- or post-operative complication were 2.5 times higher for adolescents who underwent Roux-en-Y gastric bypass compared with those who underwent sleeve gastrectomy,” study researcher Gerard Hoeltzel, a first-year medical student at Thomas Jefferson University, told Infectious Diseases in Children. “We believe this finding provides possible rationale for the observed shift in procedure use.”
Age and higher BMI were not linked to increased risk for any adverse outcomes.
“Physicians must carefully balance these risks against the prolonged exposure to severe health risks associated with obesity,” Swendiman said. “So, for the right patients, surgery may serve as a safe and effective way to improve their health, and early referral to centers that work specifically with adolescents may be beneficial.” – by Katherine Bortz
