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>50kg/m2, age>50years, DM2, hypertension, OSA, heart disease, multiple comorbidities, distance to pylorus> 4cm, bougie>40F, 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 5cm section of the pylorus or bougie>40F can increase the risk of weight loss failure.
