  3. Childhood and Adolescent Obesity Statistics Obesity rates in children age 6-11 increased from 7% to 18% between 1980 and 2010 in the US (Ogden, 2012) Obesity rates in adolescents age 12-19 increased from 5% to 18.4% between 1980 and 2010 in the US (Ogden, 2012) http://arch1design.com/blog/latest_environmental_health_news/childhood-obesity-prevalence-and-prevention/

  4. Concerns of Childhood Obesity • Obese adolescents are likely to be obese as adults (Freedman, 2005) • Increased risk of depressive symptoms and lower quality of life scores. (Schwimmer, 2003) • Increased risk of • Hypertension • Hypercholesterolemia • Hypertriglyceridemia • Hyperinsulinemia • Atherosclerosis • Metabolic syndrome • Obstructive sleep apnea • PCOS • Non-alcoholic fatty liver disease • Certain cancers (Flynn, 2006)

  5. Brief History of Bariatric Surgery 1952- First recorded operation to cure obesity was performed by Viktor Henriksonas a small bowel resection Shortly followed by jejunocolic bypasses that led to loss of fluid, electrolytes, and led to liver failure. (On left) Mid 1950’s - Jejunoileal Bypass came next and remained popular through the 1970’s (Deitel, 2012)

  6. Brief History of Bariatric Surgery (Cont’d) 1960’s - Gastric Bypass was first developed 1970’s - Roux-en-Y GB was developed and has been modified several times since. (Deitel, 2012)

  7. Brief History of Bariatric Surgery (Cont’d) 1970’s - Biliopancreatic Diversion and Duodenal Switch were also introduced to address concerns over Blind Loop Syndrome. 1980’s – Adjustable gastric banding procedures were popularized (Deitel, 2012)

  8. Brief History of Bariatric Surgery (Cont’d) 2000’s– The first sleeve gastrectomy procedures were recorded. (Deitel, 2012)

  9. Common Types of BS Performed Today http://www.hormone.org/questions-and-answers/2012/bariatric-surgery

  10. Adolescent Bariatric Surgery (ABS) Statistics US Nationwide Inpatient Sample: 2,744 ABS procedures were performed in the US between 1996 and 2003. (Black, 2013) Healthcare Cost and Utilization Project Kids’ Inpatient Database (KID), 1009 ABS procedures were performed in 2009. (Kelleher, 2013) Trends towards minimally invasive procedures Plateau of ABS procedures since 2003.

  11. Trends in Surgery Performed 2000-20009 Adapted from data in Kelleher, 2013

  12. Physical & Psychological Benefits • BMI reduction • Wide range, depending on study follow-up length • Most occurs in first year • Some alleviation of comorbid conditions • Most occurs in first year • Hard to accurately assess due to follow-up loss • Increased in quality of life • Pre-operative scores similar to children with cancer (Loux, 2008) • Significantly increased scores post-operatively (Loux, 2008)

  13. BMI Reduction • Very little long-term follow-up data • Wide range of results • RYGB, 12 month follow-up (Lawson, 2006) • Pre-op 56.5±10.1 • Post-op 35.8±6.9 • RYGB, 17.1±12.3 month follow-up(Loux, 2008) • Pre-op 54.1±7.6 • Post-op 35.1±9.3 • LSG, 12 month follow-up (Nadler, 2012) • Pre-op 52±9, • Post-op 39±8 • RYGB, 24 month follow-up (Teeple, 2012) • Pre-op 58.8±10.7, • Post-op mean 34.9±5.6

  14. Co-morbid Conditions • Most common pre-operative: • Impaired glucose tolerance • Insulin resistance • Hypertension • Sleep apnea • Dyslipidemia • Fatty liver disease • Post-operative results • Improvement in glucose tolerance and insulin resistance • Resolution of dyslipidemia • Resolution of sleep apnea • Decrease in blood pressure (Teeple, 2012; Nadler, 2012, Lennerz, 2013, Lawson, 2006, Loux, 2008)

  15. Risks and Complications of Surgery • Complications are similar to adults (Inge, 2013) • Late weight regain (up to 20%) (Xanthakos, 2008) • Recurrence of depression and eating disturbances that affect QOL (Pratt, 2009) • Marginal ulcers, small bowel obstruction, protein and micronutrient deficiencies • Gastric band slippage • Pregnancy

  16. Risks and Complications of Surgery (Cont’d) May cause problems with proper growth if children are not done growing (Barnett, 2013) Low adherence to follow-up (Lennerz, 2013)

  17. Best Practice Eligibility Criteria • BMI • >35 with severe comorbidities • >40 with any comorbities • Physiological Maturity • Height ~ 95% adult height based on estimate of bone age • Pubertal Maturity based on Tanner Stages (IV+) • Girls usually ≥13; Boys usually ≥15 • Lifestyle Change • Demonstrate ability to make sustained dietary and physical activity changes (Pratt, 2009)

  18. Best Practice Eligibility Requirements • Psychosocial Maturity • Appropriate decision making skills and understanding of risks and benefits • Social support network • Psychiatric conditions managed under treatment • Evidence of patient/family ability to comply with treatment plan pre- and post- surgery (Pratt, 2009)

  19. Future Directions Necessity of long-term data on physical and psychological outcomes Options of minimally invasive surgeries (Shebrain, 2013) Need to address possibility of weight regain Rethink criteria using BMI for weight loss surgery to catch adolescents before they become severely/morbidly obese Assert that surgeons performing surgery are qualified to do so with the special considerations of adolescents
