title: Bariatric embolization: a new and effective option for the obese patient?
abstract: Obesity is a public health epidemic in the United States, which results in significant morbidity, mortality, and cost to the healthcare system. Despite advancements in traditional therapeutic options for the obese patients, there is a treatment gap for patients in whom lifestyle modifications alone have not been successful, but for whom bariatric surgery is not a suitable option. Areas covered: This treatment gap needs to be addressed and thus, complimentary or alternative treatments to lifestyle changes and surgery are urgently needed. Recent evidence suggests that embolization of the gastric fundus ('Bariatric Embolization'), which is predominantly supplied by the left gastric artery, may affect energy homeostasis by decreasing ghrelin production. The purpose of this special report is to discuss the background, rationale and latest data on this topic, as well as provide the latest data from the ongoing BEAT Obesity clinical trial. Expert commentary: A multipronged approach is essential in the treatment of obesity. Bariatric embolization looks to treat the hormonal imbalances which contribute to obesity. If proven successful in the long-term, bariatric embolization represents a potential minimally invasive approach to treat obesity offered by interventional radiologists.
