Introduction: The aim of this study is to analyze safety and excess weight loss in the midterm follow up of patients with BMI under 35.
Methods: Prospective study, not random; including patients that underwent LSG between March 2007 and January 2010. Analysis of Gender, Age, Weight, Preoperative Body Mass Index (BMI), Operating Room (OR) Time, Excess Weight Loss, Surgical complications, Postoperative Morbidity and Mortality.
Results:Follow up 12 month (6 to 30 months) There where 184 patients. Male: 68 patients, Female: 116 patients. Mean Age 39.5±10.8 (range 15 to 70) years. Mean Preoperative Weight: 91±15 (68-118) kg. Mean Preoperative BMI: 33.3±4.1 (range 30 to 35) kg/m². Mean Excess Weight: 22.5±5.5 (range 10.7 to 34) kg. Mean OR Time 87.6±30 (60 to 150) min. Other procedures associated: Cholecystectomy, Banding Removal and Hiatal Hernia Repair. Weight Loss mean was 19 ± 7 (range 7.6 to 44.3) Kg. at 6 months and 23,4±5 (range 7.6 to 36) Kg. at 12 months. Postoperative mean BMI was 26.4 ± 3 (range 21.3 to 31.3) kg/m² at 6 months and 24.6±4 (range 20 to 27.7) at 12 monthsfollow-up. EBMIL% mean was 90 ± 10.2 (range 8.1 to 134.4)% at 12 months.Morbidity: 7 patients (3.8%).No conversions, No Mortality
Conclusions: LSG is a safe and reproducible technique in patients with BMI under 35, with low morbidity and mortality so far. In our series this results are very encouraging with excellent weight loss in the midterm. Longer follow up is needed.
