RESUMO
Methods of treating obesity in selected cases include endoscopically performed procedures, among them endoscopically placed intragastric balloons. It is a method associated with a low complication rate, traditionally reserved to treat the most obese patients. Balloon rupture or deflation and its migration into the small bowel is one of the possible complications. In some cases, the balloon moves through the digestive tract without side effects. When the balloon's displacement in the intestine is impossible, gastrointestinal obstruction occurs. We report a case of a patient with a mechanical obstruction of the gastrointestinal tract caused by asymptomatic balloon rupture and its migration into the jejunum.
RESUMO
Adipose tissue is actively involved in angiogenesis through secretion of biologically active substances. This topic has been the subject of many recent publications concerning the pathophysiology and treatment of obesity. We discuss the relationship between obesity, angiogenesis and blood rheology.
