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.
15If 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
- I would insist on a BAND
