Laparoscopic gastric banding involves placing a silicone band around the top of the stomach using key-hole surgery. There is no cutting or stapling of stomach involve.

The gastric band.

It reduces the stomach opening where the food-pipe (oesophagus) and stomach meet. The size of the opening can be adjusted or controlled to tailor for weight loss. Adjustment is done in the office during a follow-up visit. Patients normally go home on day 1 or 2 after surgery.

The size of the opening can be adjusted using the port.

The complications may involve:

  • bleeding
  • infection
  • injury to other organs
  • shoulder pain
  • tubing problem
  • nausea & vomiting
  • reflux problem
  • pouch dilation
  • blood clots

The risks of dying from this operation are less than 1 in 2000 or 3000, it is like undergoing any operation!

The average weight loss is about 50% of excess weight in 1 to 2 years. This means if you are 50kg more than your ideal weight, you are expecting to lose 25kg in the 1st to 2nd year with good follow-up.

The advantage of this procedure is it is not a bowel surgery, you still have your gastrointestinal tract intact. In order to have a restrictive effect, the band should be left in the body forever.

However, if you want to remove it later, though it is not advisable, you may elect to do so. This is the only reversible weight loss surgery!
