Gastric Bypass Surgery explained

This type of surgery is usually performed laparoscopically (also called keyhole surgery). The stomach is reduced in size to a narrow pouch, to restrict the amount of food and to reduce hunger.

A short segment of the bowel is joined (anastamosed) to the new stomach to form the bypass and to augment the weight loss effect. Gastric bypass surgery as a treatment has been performed in tens of thousands patients over the years worldwide. The surgery is relatively safe with 2 to 4% complication rates.

After The Surgery

Patients spend about 3 days in a Perth hospital after the operation and stay on liquid high protein diet for three weeks after the operation to allow all the staple lines and anastomosis to heal. After surgery, there are possible complications:
  • Bleeding
  • Ulcer formation
  • Leak from stapleline or anastamosis
  • Hypoglycemia
  • Stenosis of the anastamosis
  • Internal hernia formation
  • Small chance of malnutrition
  • Dumping syndrome (discomfort after eating sugar-rich foods)
  • Complications common with any operation such as cardiovascular and respiratory complications
  • <0.5% risk of mortality

This is only a brief description of the operation and the next step is to contact Advance Surgical Perth. Together we will go through the details of what the surgery and subsequent journey entails.

Depending on your consultation, your Surgeon may also discuss the Mini Gastric Bypass as a surgical option. Research supports this as a simple alternative to the standard surgery.

Mini Gastric Bypass

The Mini Gastric Bypass is a newer form of Gastric Bypass surgery. This surgery is performed laparoscopically and, like a traditional bypass, involves making the stomach smaller. A Mini Gastric Bypass is slightly easier to perform, and usually would take less time than the traditional Roux-en-Y Bypass. Read more about this newer bypass procedure here.
