Sa1389 Intragastric Balloon in the Treatment of Obese Population: Weight Loss and Complications Christian A. Sanchez*, Magdalena Ramos Mejia, Carolina Bolino, Luis E. Caro, Cecilio L. Cerisoli Gedyt, Buenos Aires, Argentina Introduction: Obesity, a new global epidemic, is associated with multiple metabolic diseases and high mortality. The failure of long-term conservative treatment led to the emergence of new therapies. The intragastric balloon (IGB) is an effective, well tolerated and minimally invasive procedure for loosing weight. Objectives: 1. Estimate the weight loss in patients who had IGB inserted for at least 6 months. 2. Describe immediate and mediate complications. Materials and Methods: We included patients R 18 years with BMI R 30 kg/m, R 35 kg/m with comorbidities or patients at high risk or non-conforming for surgery despite its indication. Contraindications for IGB were exclusion criteria. The study took place at a gastroenterology outpatient center between September, 2009 and September, 2013. Design: Interventionist, prospective, comparative, longitudinal study. Methods: Patients were selected by a multidisciplinary team and included consecutively. The IGB was placed according to its technique and the patient remained hospitalized for 12-24 hours for observation for eventual post placement symptoms. Diet, exercise plan and a schedule of monthly visits were prescribed at discharge. We evaluated the mean weight loss after 6 months and complications were recorded as immediate (!7days) and mediate (O 7days). Ethics: the protocol was approved by the local IRB. Statistical analysis: VCCstat 2.0. package; 95%CI were calculated; ANOVA test. Results: We evaluated 154 patients, 23 required IGB early removal. Finally 94 patients were analyzed. 72% (68/94) were women, mean age 42,25 11,5 years, with no difference between genders, mean BMI: 37.22 4.85 kg/m (range 29.03 to 58,11). The balloon was inserted for a median time of 208,50 30 days (range 162-333). Comorbidities were registered in 48% (45/94). 1. According to diet and exercise compliance the sample was stratified into five groups: Compliance to diet (G1), to exercise (G2), to both measures (G3), no compliance to both measures (G4), no nutritional monitoring at our institution (G5). The weight loss average in each group is detailed in the table 1. Immediate complications occurred in 44% patients (95%CI 34-55; 42/94), and were registered as follows: vomiting 53% (n:22), nausea 27% (n:11), epigastric pain 14% (n:6). Mediate complications were recorded in 2.1% patients (95%CI 0,3-7,5; 2/94). Conclusions: The weight loss varied according to treatment compliance. Patients who were compliant to diet and exercise lost more weight than the other groups. Early complications were more frequent.
