Dr Jon Morrow manages a number of general surgical conditions. Operations can be performed either by a minimally invasive approach (keyhole surgery) or as an open procedure. The best method will be tailored to you.

Successful weight loss requires a combination of both lifestyle changes (including diet and exercise) and surgery. A range of different weight loss surgical procedures (band, sleeve, bypass) are available. Any and all options can be discussed.

Gallstones are very common and can cause a variety of conditions ranging from minor to severe. Surgical removal of the gallbladder via keyhole surgery is the recommended treatment.

Hernias come in all shapes and sizes and should, if possible, be fixed. They can be repaired via a traditional open approach or by using minimally invasive (keyhole) surgery.

Laparoscopic Gastric Sleeve



Laparoscopic (keyhole) gastric sleeve is performed under general anaesthesia. An incision is made below the lower margin of the left rib cage, a port is placed through this incision, and CO2 introduced to inflate the abdomen and create a working space. A camera (laparoscope) is then introduced and under direct vision, a further 4 incisions are made. The left lobe of the liver is lifted to adequately expose the stomach. The omentum (an apron of fat attached to the stomach) is detached from the stomach. The stomach is then stapled and cut to create a narrow tube with a volume of between 100-150ml. The remaining 90% of the stomach is removed via an incision on the right side of the abdomen. The skin is closed with an absorbable suture.


Expected Weight Loss

Approximately 50-60% of excess weight.
