Objectives: Analyze the evolution of body mass index (BMI) and percentage of excess weight loss (PEWL) after bariatric surgery; compare adjustable gastric banding (LABG) vs laparoscopic gastric bypass (LGB).
Methods: Cohort study. Inclusion criteria: all cases underwent laparoscopic bariatric surgery; n=89; 9 patients were excluded for incomplete follow up. Differences between the 2 groups were evaluated using the Student t-test; P<0.05 was considered significant.
Results: n=80 (35 LABG/45 LBG).
| Sex (male/female) | Age (years) | Hospital stay (days) | BMI (kg/m2) | |
| LABG | 8.6/91.4 (%) | 40±12.7 | 6.3±3.2 | 43.7±6.6 |
| LBG | 28.9/71.1 (%) | 41.7±10.7 | 16.4±11.4 | 50.8±7.9 |
| N (LABG/LBG) | LABG | LBG | P | ||
| 3 months | 35/45 | BMI (kg/m2) | 37.4±5.5 | 39.4±5.8 | – |
| PEWL | 30.1±10.7 | 39.4±9.7 | 0.001 | ||
| 6 months | 33/45 | BMI (kg/m2) | 35.7±5.2 | 35.2±6.3 | – |

| 12 months | 27/43 | BMI (kg/m2) | 34.6±4.8 | 31.5±5.6 | – |
| PEWL | 46.8±18.1 | 69±17.3 | 0.001 | ||
| 24 months | 17/24 | BMI (kg/m2) | 34.9±4.4 | 32.4±5.8 | – |
| PEWL | 41.6±19.8 | 66.1±20.5 | 0.001 |
Conclusions: Bariatric surgery is a successful treatment to obtain an adecuate weight loss. The best results are observed during the first year. LBG had better results.
