1263 – Intra-abdominal Vagal Nerve Inhibition for the Management of Obesity

-

Intra-abdominal vagal blocking for obesity, aims to achieve weight loss by utilising a less invasive form of vagal inhibition than vagotomy. Intra-abdominal vagal blocking for obesity is administered with a system which consists of two implantable flexible leads with electrodes. The electrodes are placed laparoscopically, under general anesthesia, at the anterior and posterior intra-abdominal vagal nerve trunks and connected to an implantable neuroregulator that is placed subcutaneously on the abdominal wall below the rib margin. The neuroregulator is powered by an internal rechargeable battery. A mobile, external controller that is connected via a small, flexible cable to a cutaneous transmit coil positioned over the implanted device allows the clinician to control and upload information from the device. Treatment can be reversed by simply turning off the neuroregulator.

Overweight and obesity are defined as abnormal or excessive fat accumulation that may cause adverse health effects. Obesity is a multifactorial disease that may have a variety of underlying causes, including physical illness, genetics, behavioural and psychological factors, and lifestyle choices. Obesity is associated with an increased risk for a number of comorbidities.
