Weight Loss and Eating Pattern 7 Years After Sleeve Gastrectomy: Experience of a Bariatric Center of Excellence.

Report the analysis from a single center series of consecutive primary sleeve gastrectomy (SG) on the factors affecting weight loss at long term. Patients submitted to primary SG with a follow-up of 7 years were screened. Weight loss was evaluated with %excess weight loss (%EWL) and %excess BMI loss (%BMIL). Weight regain (WR) was defined as in increase of 25% of the obtained %EWL and insufficient weight loss (IWL) as loss < 50% EWL. Eating behaviors were evaluated with 7 days record (7dR). All the variables potentially affecting the weight loss were cross-matched for correlation. The study population was divided in three groups: group A (WR), group B (IWL), and group C (sustained weight loss) for comparative analysis. A total of 86 patients (21 M/65 F) with a preoperative BMI of 47.08 ± 6.15 kg/m Our data demonstrated that long-term results (7 years) of SG are strongly related to eating habits and patient's behaviors.
