Laparoscopic Gastric Bypass Surgery on the Gold Coast

Laparoscopic Gastric Bypass

Ideal patients:

  • Especially good for diabetics.
  • Patients with high triglycerides or cholesterol.
  • Patients with reflux disease.

Gastric bypass surgery provides the most robust long term weight loss and has the greatest effect upon improving diabetes and metabolic syndrome. After a gastric bypass, some diabetic patients are able to eliminate all diabetic medications within days or even hours of the operation. Bypass also has the most dramatic effect on lowering triglycerides and cholesterol. The bypass procedure is extremely effective at treating gastro-oesophageal reflux disease, in fact it is becoming common to perform a bypass in patients with severe debilitating reflux who have failed medical therapy and even prior operations for reflux. It is also a salvage procedure for those who have had complications with prior bariatric procedures.

There are various styles of gastric bypass, the most common is the Roux-en-Y gastric bypass. This procedure is the most common procedure worldwide and is gaining popularity in Australia due to its strong longer term effect on weight loss. The procedure takes about 1 to 1 ½ hours for a primary procedure, and generally requires a 2 night stay in hospital.

The gastric bypass surgery procedure involves dividing the upper portion of the stomach and leaving a small pouch of about 30ml's capacity. This creates a restricting effect and dramatically reduces the amount of food able to be eaten. Part of your small bowel is then attached to this small pouch of stomach, therefore bypassing the majority of the stomach and upper part of the small bowel where the digestive juices are formed. This leads to slightly decreasing absorption of carbohydrates and fat.

There are various other types of gastric bypass surgery variations, such as the mini gastric bypass, fixed ring bypass, and short limb gastric diversion. These options would be specific to certain patients for various reasons.

Mini Gastric Bypass

A longer thinner gastric pouch which is similar to a sleeve gastrectomy however the small bowel is attached to the bottom of the sleeve.  This bypasses about 1.5-2 metres of the small bowel. This operation is extremely good for diabetic patients.

Fixed ring bypass

A small ring is placed above the gastroenterostomy which may help prevent dilatation over a long period of time. This ring can also be used on sleeve gastrectomy.

Short limb gastric diversion

Same as a standard bypass however with a larger anastomosis and shorter alimentary and biliary limb. Mainly to relieve incapacitating reflux rather than provide weight loss.

 

It is important to have long term follow up with your surgeon or an appropriately trained associate after a gastric bypass operation.
