© 2017 AEC Introduction Sleeve gastrectomy (SG) has become a technique in its own right although a selective or global indication remains controversial. The weight loss data at 5 years are heterogeneous. The aim of the study is to identify possible prognostic factors of insufficient weight loss after SG. Methods A SG retrospective multicenter study of more than one year follow-up was performed. Failure is considered if EWL > 50%. Univariate and multivariate study of Cox regression were performed to identify prognostic factors of failure of weight loss at 1, 2 and 3 years of follow up. Results A total of 1,565 patients treated in 29 hospitals are included. PSP per year: 70.58 ± 24.7; 3 years 69.39 ± 29.2; 5 years 68.46 ± 23.1. Patients with EWL < 50 (considered failure): 17.1% in the first year, 20.1% at 3 years, 20.8% at 5 years. Variables with influence on the weight loss failure in univariate analysis were: BMI > 50 kg/m 2 , age > 50 years, DM2, hypertension, OSA, heart disease, multiple comorbidities, distance to pylorus> 4 cm, bougie > 40 F, treatment with antiplatelet agents. The reinforcement of the suture improved results. In multivariate study DM2 and BMI are independent factors of failure. Conclusion The SG associates a satisfactory weight loss in 79% of patients in the first 5 years; however, some variables such as BMI > 50, age > 50, the presence of several comorbidities, more than 5 cm section of the pylorus or bougie > 40 F can increase the risk of weight loss failure.
