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


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).


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.


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