BISPO, M. et al. O Balão Intra-Gástrico no Tratamento da Obesidade: Avaliação da Sua Eficácia, Segurança e Tolerabilidade. []. , 15, 3, pp.103-109. ISSN 0872-8178.

Background: The main goal proposed by the WHO in obesity treatment, in order to reduce cardiovascular risk and related comorbidities, is a 10-15% weight-loss. Aims: To characterize and analyze short and long-term efficacy, safety and tolerability of BioEnterics® Intragastric Balloon (BIB) in obesity treatment. Patients and Methods: Retrospective study on data of 210 BIB procedures in 194 patients, between October/2000 and June/2007. Most patients presented with morbid obesity (mean BMI 47,8Kg/m2) and heavy comorbidities. Average BIB stay was 7 months. Results: On BIB removal, the mean weight-loss was 12,9%. “Clinical success” (weight-loss ≥10%) was achieved in most cases (60,5%). In two groups of 52 hypertensive and 30 diabetic patients, there was a 61,5% and 66,7% improvement in these comorbidities, respectively, during treatment. There were no major complications associated to BIB. On longterm analysis (12 month after BIB removal) of a 91 patients cohort, global weight-loss was 5,6%, being significantly higher (>2-fold) in patients over 50 years-old. Conclusions: BIB is safe, shows satisfactory short-term cli nical success rate, with improvement in co-morbidities. On long-term, higher efficacy was seen in older patients.
