JIMENEZ BAZZANO, MC. Efficacy of the use of the intragastric balloon in the temporary control of obesity in Paraguay. Mem. Inst. Investig. Cienc. Salud [online]. 2012, vol.10, n.1, pp.36-45. ISSN 1812-9528.

The intragastric balloon is a non-surgical procedure indicated for the control of obesity. It is considered more efficient than the conservative treatment, which has less risk than the surgery, but there is still a lack of consensus about its indications and there is little information about its limitations. The present study describes the experience of the first 100 cases in Paraguay where 32% of obesity is estimated in the urban population. The objective of this study was to determine the efficacy of the intragastric balloon in the decrease of the weight and waist circumference of obese patients subjected to this treatment. Since October 2004 to December 2008, 100 patients were subjected to the placing of an intragastric balloon after a clinical, psychological and nutritional evaluation. They received a hypocaloric diet and indications of daily physical activity. Seventy six women with a mean age of 36±21 years and 24 men with a mean age of 37±19 years were evaluated. The initial weight was 105±23 kg in women and 134±27 kg in men, presenting a waist diameter above the normal values (110 and 132 cm respectively), a mean weight of 112±23 kg, a BMI of 40 and waist diameter of 115 cm. In the result analysis, the weight values decreased significantly after the surgery being the median values 112 (IC 95%: 96.4 to 113.9 kg; p< 0.0001) at initial level and 88 (IC 95%: 80.0 a 89.3) at final level providing a net difference of 24 kg in a period of six to eight months. In relation to the body mass index (BMI), the change observed was one obesity degree of difference going from morbid obesity and grade III to obesity grades II and I. The values were the following: median of 38 kg/m2 (IC 95%: 36.4 to 39.9) at the initial level and median of 31.0 kg/m2 (IC 95% 29.4 to 33.9) at the final level. The results show significant losses of weight, BMI and waist diameter. This can be achieved combining the intragastric balloon, restricted diet and behavioral support therapy. The waist diameter, a very important risk factor for cardiovascular disease, showed an important decrease.
