Gastric Sleeve Surgery

The vertical sleeve gastrectomy (also called sleeve gastrectomy or gastric sleeve surgery) is a stapling procedure in which approximately 80 percent of the stomach is removed. 

This results in a tubular stomach, or “sleeve”, that will hold approximately 3 to 4 ounces of food or drink.

This surgery is typically performed laparoscopically, using minimally invasive techniques to minimise the stress on the body and maximise recovery times from the procedure. This is an irreversible surgery although the stomach can dilate later in life. 

This is one of the gastric procedures that Dr Wilkinson performs in Hobart, however a thorough discussion about the plissés and downsides of all types of anti- obesity surgery is undertaken before making a choice as to which type is best for any individual. Dr Wilkinson carries out consultations in Hobart, Launceston and Burnie.

Vertical Sleeve Gastrectomy

The amount of stomach left behind is calibrated with a sizing tube, to ensure an evenly sized channel for food passageSimilar to other digestive restrictive procedures, the gastric sleeve limits the amount of food intake and leads to an earlier feeling of satiety at mealtime.

Additionally, the portion of stomach that is removed contains many of the cells in the gastric part of the body that produce a hormone called ghrelin, which is associated with the sensation of hunger. The removal of these cells through removing the stomach can limit the sensation of “feeling hungry” in the patient. 

It is not clear how much effect a decrease in ghrelin levels has on postoperative weight loss, but some patients do report feeling less hungry after a gastric sleeve procedure. (This is also true of other weight loss procedures)

Whilst this surgery is irreversible, many obese patients find that they lose upwards of 55-70% of their body mass within the first year.

• This procedure is not reversible; once the portion of stomach is removed, it cannot be put back into the body
