  1. Laparoscopic Adjustable Gastric Banding for the treatment of adolescent morbid obesity. The University of Illinois at Chicago experience Holterman M 2,Browne A 2, Horgan S 1 Browne N 2 and Holterman A2. From the Department of Surgery, Divisions of Minimally Invasive Surgery1 and Pediatric Surgery 2, and the New Hope Pediatric & Adolescent Weight Management Project at the University of Illinois at Chicago

  3. 4 The FDA trial for “LAGB® Laproscopic adjustable gastric banding as a treatment for morbid obesity in adolescents”at UIC • 1999 The University of Illinois at Chicago (UIC) - FDA trial B • 2001 FDA approval for the LAP-BAND® device for laparoscopic adjustable gastric banding (LAGB) weight loss procedure in adults • 2004 (December) UIC receives FDA IDE for Lap-Band placement in 50 morbidly obese adolescents: A safety and efficacy trial

  10. Adult protocol Modified Adolescent protocol 10 LAPBAND size: 10 or 11 cm Diet Week 1: Liquid Week 2-3: Blended diet Week 4-6: Soft Food. Week 7 and after: 3 small (<4oz) meals/day No liquid with meals Eat slowly and chew well Stop eating when full Adjustment (using barium swallow) First adjustment at 6 weeks Readjustment criteria 1) if no longer feels full with meals 2) if do not loose >5lbs/month or > 2lb/wk 3) increased hunger sensation Follow up: RTC suggested 6 times/year or if meet readjustment criteria LAPBAND size:11 cmVG Diet Same Adjustment same Readjustment criteria Same Follow up: 1. RTC1wk., 6 wks, then monthly. 2. FDA study visits: q 3 m x 1 yr, & q 6m x 4yr 3. Close phone and Email contact

  11. THE TEAM CONCEPT 1 • COMPREHENSIVE AND INTEGRATED CARE • The surgeons, the pediatricians, the support team, the research team • The Adult Bariatric Surgery team- • SUPPORT for the Adolescent Bariatric team: • Advanced laparoscopic surgeon • Former PI in the FDA trial B; >700 cases of LAGB • EXPERIENCE in LAGB surgical and medical management • CONTINUITY OF CARE for the adolescent bariatric patients • The Adolescent Bariatric Surgery team. • The PRIMARY care surgeons for the patients • Department of Surgery, Division of Pediatric Surgery • Advanced laparoscopic surgeon • ASBS criteria

  12. Team Clinical Evaluation • Psychologist • Adolescent Pediatrician • Nutritionist • Physical Therapist • PNP (Nurse Coordinator) • Pediatric Surgeon

  14. 11 SUMMARY • In this small early series of the FDA trial, LAGB as a treatment for MO in the adolescents: • Is associated with short operative time, brief hospital stay and no mortality. • Is effective and safe CONCLUSION The highest challenge of LAGB treatment for morbid obesity in the adolescents is the post-operative management. Close and long term follow-up, ensuring diet compliance and maintaining a high index of suspicion for early detection and treatment of pouch dilatation are essential.

  15. If this was your child, what would you do? • 1/200 vs 1/2000 • Operate on 100,000 children: 500 vs 50 • 3 to 4 fold greater morbidity • Probably equal long term efficacy • Compliance problems either way • ??LAGB first and if not successful:->>> gastric bypass • 0.20 X 0.03 = 0.006 • 0.006 + 0.05 = 0.056 • 0.056%<0.5% (9-fold safer) • I would insist on a BAND

  16. The Adolescent Bariatric Medical Team: Adolescent obesity specialist (adolescent pediatrician) Pediatric subspecialties (pulmonology, hepatology, etc) The Adolescent Bariatric Clinical Support Team: Nurse Coordinator (Pediatric Nurse Practitioner) Psychologist Nutritionist Exercise specialist (Physical therapist) The Adolescent Bariatric Program Support Team: Hospital Administrator Project Coordinator Medical insurance Coordinator Public relation Coordinator The Researchers School of Medicine (obesity-related liver disease, metabolic syndrome Inflammatory states, pulmonary disease) School of Nutrition (Body fat composition and fat metabolism School of Public Health ( Economics of obesity, Diet/nutrition and environmental factors)

  17. EXCLUSION CRITERIA FDA Study • Intention or need to have another surgical procedure for weight reduction within 12 months of Lap Band placement. • History of congenital or acquired anomalies of the G.I. tract, such as; congenital or acquired intestinal telangiectasia, Crohn's disease or ulcerative colitis; severe cardiopulmonary disease or severe coagulapathy; hepatic insufficiency or cirrhosis. • Pregnancy or intention of becoming pregnant in the next 12 months. • Presence of psychiatric problems or immaturity which would compromise cooperation with the study protocol. • History of previous bariatric surgery, intestinal obstruction or adhesive peritonitis. • Presence of localized or systemic infection at the time of surgery. • Chronic use of aspirin and/or non-steroidal anti-inflammatory medications and unwillingness to discontinue the use of these concomitant medications. • History of gastric or esophageal surgery. • Use of weight loss medications. • History of esophageal dysmotility disorders. • Eating disorders.
