Novel technologies and techniques in bariatric surgery.

Obesity has been on the rise globally and more people are now clinically obese than ever before in the US. This issue has a significant impact on both health and cost to healthcare systems. Bariatric surgery is efficacious in treatment of obesity but only in late stages of the disease, and there is a requirement for less invasive techniques/devices to treat obesity at earlier stages. Currently a number of these are either in clinical trials or have recently been approved by the Food and Drug Administration for weight loss. This review aims to give an overview of the newer technologies and techniques being used in bariatric surgery. It will also give a glimpse into future methods and those that have fallen short in recent times.
