VBLOC therapy

This is an emerging surgery with a short track record that can not be compared with gastric banding and gastric sleeve surgery.

VBLOC refers to a technical device for weight loss surgery. It is a programable electronic device that is implanted in the abdomen around the vagal trunks near the gastro-oesophageal junction. It induces an intra-abdominal sub-diaphragmatic intermittent vagal block via a radio-frequency system. This signalling results in improved satiety, reduced calorie intake, weight loss, reduced hunger and improvements in obesity related co-morbidities such as diabetes mellitus and hypertension. The effectiveness of the device appears to be greater when the device is operating more than 12 hours a day compared with just a few hours a day.

 

The Maestro(R) Rechargeable System by EnterMedics Inc is the VBLOC device that is now included on the Australian Register of Therapeutic Goods but it is not commercially available in the United States.

 

The VBLOC therapy device under-went rigorous trials before it gained approval.

 

This device is still in its infancy and not many surgeons have adopted it yet.
