PubMed Abstract

BACKGROUND: Severe or extreme obesity in children and adolescents is a progressive damaging disease, increasingly requiring surgical treatment. Timing and choice of operation are controversial.

METHOD: In the last 16 years, we performed open biliopancreatic diversion with duodenal switch (DS) in 13 adolescents aged 15-17 years, who have been followed up for 2-16 years (mean, 10.6 years); three with Prader-Willi syndrome (PWS) are presented separately.

RESULTS: Among the ten non-PWS children (7 girls), no deaths or perioperative complications were reported, mean body mass index (BMI) decreased from 55.9 +/- 14.0 to 28.8 +/- 33.7 kg/m(2) (% excess weight loss (EWL) = 82.1 +/- 10.5%), and none have regained weight. All comorbidities were cured except asthma, which improved in one patient. There were two reoperations: one for intestinal obstruction and one for post-anastomotic ulcer. Glucose and lipid metabolism improved, while vitamin and mineral deficiencies were mild and rare. Five of the seven girls gave birth to 11 children, aged 2-12 years, two of whom are overweight but not severely obese. Neurodevelopment is age-appropriate in all 11 individuals. PWS children, aged 15-16 years, had postoperative respiratory and infectious complications necessitating hospitalizations of 13-22 days (versus 5.1 +/- 11.2 days in non-PWS). Weight loss and comorbidity improvement lasted approximately 5 years, providing improved quality of life for patient and family. One PWS patient died from complications after reoperation for weight regain after 4 years. One was reoperated after 6 years and the third is considering reoperation 14 years after primary DS.

CONCLUSION: The beneficial effects of DS in adolescents exceed the risks, even in the presence of PWS.
