The Orbera, Spatz3 and Allurion gastric balloons share a number of similarities, but there are also some key differences.
Duration of Therapy
The Allurion Balloon is designed to self-deflate after approximately 4 months in the stomach.
The Orbera Balloon is designed to stay in the stomach for up to 6 months, at which time it must be removed by endoscopy.
The Spatz3 Balloon is designed to stay in the stomach for up to 12 months, at which time it must be removed by endoscopy.
Implantation and Removal Procedure
The Orbera Balloon and the Spatz3 Balloon are both implanted and removed in much the same way – an endoscopy performed under sedation (light anaesthetic). Both procedures require a short visit (2-4 hours) to one of our associated hospital facilities.
The Allurion Balloon comes packaged into a capsule which you are able to swallow with the support of a specialist doctor during a short clinic visit. X-rays are taken to confirm the balloon is correctly positioned before it is filled with 550mL of fluid. No anaesthesia or endoscopy is generally required to implant or remove the balloon. After approximately 4 months in the stomach, a special valve on the balloon opens, allowing the fluid to escape, and the empty balloon then passes through the rest of the intestine and into the toilet. In rare cases, the balloon may be excreted through the mouth, and in very rare cases, an endoscopy or surgery may be required to remove the balloon.
The Orbera Balloon and the Allurion Balloon are both fixed-volume balloons – once they are implanted they cannot be increased or decreased in size.
The Spatz3 Balloon is the world’s only adjustable gastric balloon, meaning that the balloon can be increased or decreased in size after it has been implanted. The adjustment procedure is similar to the procedure to implant or remove the balloon, requiring a short endoscopic procedure under sedation. The Spatz3 Balloon can be increased in size to improve weight loss, or decreased in size to alleviate symptoms of intolerance or improve comfort.
Average Weight Loss
The Orbera Balloon and the Allurion Balloon have demonstrated similar weight loss results in clinical trials – approximately 10-15% TBWL (ie. a person with a starting weight of 100kg would lose 10-15kg on average).
Clinical trials of the Spatz3 Balloon have demonstrated the highest average weight loss of any gastric balloon – approximately 15-20% TWBL (ie. a person with a starting weight of 100kg would lose 15-20kg on average).
