New Weight-Loss Surgery Technique
Seattle Times, 19th July 2010
A new weight-loss surgery technique is being developed by surgeons in North Carolina. The new technique, called vertical sleeve gastrectomy, requires only one incision and is operated through the belly button.
A new Spider surgical tool is required for this type of surgery. Vertical sleeve gastrectomy cuts the stomach down to 20% of its normal capacity. The name suggests the shape of the stomach that remains after the surgery.
How is it possible for the surgeon to operate through the belly button? The Spider tool contain working arms that unfold inside the patient so that the surgeon can access the areas he needs.
Dr. Quebbemann who carried out the operation using the new tool said: “Instead of making several incisions to place my surgical instruments, I simply make one small incision, hidden in the patient’s belly button, and insert the Spider. I then expand the internal portion of the device, similar to expanding an umbrella. This allows me to clearly see the anatomy and accurately perform the operation.
At the end of the procedure, I simply close the system, and remove it through the small incision, leaving almost no visible scar.”
Vertical sleeve gastrectomy is one of the fastest growing types of bariatric surgery. It is said to be most effective while operating on severly obese patients but can also be used to treat patients with BMI of 30 to 35.
The new technique is an alternative to the gastric bypass and lap-band surgery.
The Spider tool is produced by TransEnterix Inc. of Durham, N.C. and was approved by the Food and Drug Administration last year.
Surgeons highlight that weight-loss surgery is not a quick solution. Patients have to realise that they need to change their life-style, exercise and start a healthy diet.
As vertical sleeve gastrectomy is a new technique, there isn’t much data about long-term
benefits and risks.
