INTRODUCTION: The long-term results in sleeve gastrectomy (SG) have been reported in few publications. None of them has evaluated the importance of preoperative BMI (kg/m2) in the final results. OBJECTIVE: To determine the loss and regain of weight after SG, determining the influence of preoperative BMI in final results. MATERIAL AND METHODS: This prospective study included all patients operated between 2006 and 2010. Exclusion criteria corresponded to patients with Barrett's esophagus, type 2 diabetes, and hiatal hernia greater than 3 cm. Patients were followed and controlled "face to face" by the main author. RESULTS: From 109 original patients included in this study, 102 (93.5%) completed the late follow-up. Patients were divided into four groups: (a) I-29 patients with BMI 32.1-34.9; (b) II-56 patients with BMI 35-39.9; (c) III-20 patients with BMI 40-49.9; and (d) IV-4 patients with BMI > 50. There was a significant decrease in the BMI 12 to 24 months after surgery. At the late control, patients in groups III and IV regained weight in 85 and 100%, respectively. Patients in groups I and II had 3.6 and 38% of weight regain. CONCLUSION: The changes in weight after SG are directly related to preoperative BMI: the higher this value, the higher the percentage of failure and weight regain late after surgery. Besides, laparoscopic SG seems to be an adequate operation at late control in terms of loose of weight after surgery in patients with a BMI less than 40 kg/m2 before surgery.
