Sleeve Gastrectomy

Introduction to Gastric Sleeve Surgery

A sleeve gastrectomy procedure involves the surgical permanent removal of approximately 85% of the volume of the stomach. The surgery is performed using laparoscopic (that is 'keyhole' or 'minimally invasive') techniques.

Once complete, a patient is physically unable to consume large amounts of food at one sitting, as the 'new' stomach, which is now in the form of a long tube, holds only 200ml compared to the volume of a normal stomach which is around 1,500ml (1.5 litres). Apart from the change in the size of the stomach, all other aspects of digestion remain unchanged - with food continuing through the stomach and into the intestines as normal, and nutrients being absorbed in the normal way.

The procedure is also known as 'gastric sleeve surgery' or 'vertical sleeve gastrectomy', and may be a suitable option for patients who need to lose a substantial amount of weight. It is a different procedure to gastric banding. The benefits of the procedure include...

  • Short recovery time.
  • Rapid weight loss.
  • Improves a number of conditions, such as high blood pressure, diabetes, high cholesterol, sleep apnoea.

The Gastrectomy Procedure

A sleeve gastrectomy is performed using laparoscopic techniques under a general anaesthetic. It is a permanent procedure where the existing stomach is reduced in size by removing a section. What remains is a 'sleeve' with a shape similar to a banana.

Postoperative Instructions

After surgery it will be impossible to consume large meals. Instead dietitians advise patients to aim to eat 4-6 smaller meals every day. Patients following these guidelines can expect to lose around 65% of their excess weight within a year.
