RESULTS
71 patients had the balloon implanted for the second time at least six months (mean of 25.74 ± 12.94 months) after the removal of the first balloon. Of these, 25 had an early removal (balloon explant less than a month after implantation) of the balloon due to intolerance (35.21%). Of the remaining 46 patients, 35 were women. The percent weight regain in relationship to first treatment weight lost was 99.71±44,9 (range: 5.00-255.56). The patients showed a significant lower final BMI (mean: 29.61±4,20 kg/m2; range:20.08-42.98) than the initial BMI (mean: 35.27±5.49 kg/m2; range: 27.05-52.96) (p<0.0001) (Figure 1 ).
The average weight loss in kilograms was 15.27 ± 8.78 (range 3.0-35.0). The percent total body weight loss (%TBWL) was 15.54 ± 7.95 (range: 3.26-40.23), and the percent excess weight loss (%EWL) of 60.57 ± 35.37 (range: 10.87-194,61). The success rate of treatment (>25% EWL) was 91.30%. However, BMI reduction, weight loss in kg, %TBWL and %EWL were significantly lower than in the first treatment (p<0.0001, p<0.0001, p<0.0001, p=0.0004, respectively) (Figures 2 to 5 ).
