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 Adjustable Gastric Band

Indications BMI>40kg/m2 BMI>35kg/m2 with co-morbidities Specialist recommendation Description Laparoscopic (keyhole) adjustable gastric banding 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 introduced through this port and under direct vision, a further 4 incisions are made in the abdomen. The left lobe of the liver is lifted to adequately expose the stomach. A space is created around the top of the stomach and the adjustable gastric band is placed like a belt. The stomach is stitched over the top of the band. A small pocket is created under the skin of the abdomen where the access port will be placed and a piece of tubing from the band is connected to this access port. The skin is closed with an absorbable suture. Follow up: You will be seen one week after surgery then every 4 weeks for the first 12 to 18 months for an adjustment of the band. This requires needling the port via the skin, and injecting or removing water from the band, depending on the degree of restriction you feel with food. The dietician will see you within 4 weeks of surgery. Expected Weight Loss: Approximately 45-50% of excess weight. Advantages Low risk No stomach stapling Removable Disadvantages Prosthetic device – risk of complications High chance of revision Intensive follow-up – every 4 weeks for the first 12 to 18 months Limited food choices Complications Death (1/2000) Perforation of organ Bleeding – from spleen, liver, omentum (an apron of fat attached to the stomach), skin incisions Conversion to open procedure Prolonged hospitalisation Further surgery/procedures Infection – wound, chest, urine, drip site, intra-abdominal Deep venous thrombosis (blood clots in legs) Pulmonary embolus (blood clots in lungs) Myocardial infarction (heart attack) Cerebrovascular accident (stroke) Anaphylaxis (allergic reaction) Band slip – part of the stomach may slip through the band Pouch dilatation – the stomach above the band may expand over time Band erosion – the band may erode through the stomach wall over time Food intolerance – there may be many foods which you are unable to eat Port infection – the access port may get infected Port access problems – there may be difficulty accessing the port with the needle System leak/failure – there may be a hole or kink in the tubing, making adjustments difficult Frequently Asked Questions How long will the surgery take?  30 to 60 minutes.
