Intragastric balloon placement in the treatment of overweight and obesity: Experience at a Mexican referral center. / Colocación de balón intragástrico en el tratamiento del sobrepeso y obesidad: experiencia de un centro de referencia en México.

INTRODUCTION AND AIM: Intragastric balloon therapy is a temporary, minimally invasive method for inducing weight loss. Any balloon with a volume of 400mL induces satiety and delayed gastric emptying. The aim of the present study was to demonstrate its safety and efficacy. MATERIALS AND METHODS: We analyzed the safety and effectiveness of balloon placement in relation to weight loss in 128patients. Subgroups were compared through the Student's t test, ANOVA test, and the chi-square test, depending on the type of variable and the number of groups evaluated. Statistical significance was set at a P≤.05 to evaluate weight loss. RESULTS: Mean weight loss after balloon therapy was 10.7kg, with only 2 cases of complications due to oral feeding intolerance. Mean length of time with the balloon was 8months. There were no complications after 6months, but no further weight loss either (P=.540). Final weight loss versus initial weight loss was significant (P=.000). There was greater weight loss in the group that attended the bimonthly control appointments than in the group that did not: 12.7kg vs. 7.26kg (P=.000). CONCLUSIONS: The rates of the adverse events of intolerance and complications were very low in our study, compared with results in the literature: 1.6% vs. 4.7% and 0% vs. 3%, respectively. Intragastric balloon placement had better results when the patients attended the control appointments. Intragastric balloon therapy is a safe and efficacious method for reducing weight in patients with overweight and obesity.
