Who benefits from gastric banding?
BACKGROUND
In the present study, criteria were investigated to predict major benefit after laparoscopic adjustable gastric banding (LAGB).


METHODS
85 morbidly obese patients were operated with LAGB between 1999 and 2005. Seventy-one of these patients were analyzed according to several possible predictive characteristics for success as the primary endpoint. Success was defined as excess body weight loss (EBWL) >50% and no band removal. Median follow-up was 27 months (range 8-90 months).


RESULTS
In total, median EBWL was 43% (-41 to 171.5%) with a decrease in BMI of 8.0 kg/m(2) (-9 to 35 kg/m(2)). Success rate was 37% (n = 26). These patients were compared to all other patients (n = 45). Significant success predictors were baseline absolute BW, EBW, BMI (p < 0.01), BMI with a threshold value of 50 kg/m(2) (p = 0.02), and female sex (p = 0.02) as well as postoperative vomiting (p = 0.02), eating behavior and physical activity after LAGB (p < 0.01). Baseline EBW and change in eating behavior after surgery were identified as independent predictors in multivariate analysis.


CONCLUSIONS
Patients with a lower excess body weight who improve especially their eating behavior after surgery have the highest chance of success after LAGB.
