Since the mid-1980s, intragastric balloons have been used to treat weight loss. Since the first gastric balloon treatment, the GarrenEdwards Gastric Bubble (GEBG) in 1985, there have been a lot of advancements in the gastric balloon segment.
Today there are several leading gastric balloon implants to choose from, namely the Orbera, ReShape Duo, and Spatz (not currently approved in the United States). With advancements in endobariatrics, several promising, yet experimental, procedures are sure to come to market within the next few years. This comparison is based on readily accessible studies that have been published.
Note: ReShape Duo and especially Spatz have limited data in research journals. Updated: August 29th, 2016.

Overall, the Spatz IntraGastric Balloon has limited research, so we truly can’t compare its efficacy with the Orbera and the ReShape Duo. However, based on their initial weight loss data, this adjustable band seems promising. They say that 80% of the weight loss, occurs in the first three months, so the benefits of having an adjustable balloon is that it can help accelerate weight loss or minimize the side effects easily.
In comparison between the Orbera and ReShape Duo, it shows that the Orbera and the ReShape are similar in terms of expected weight loss, but the Orbera seems less risky, with a lower percentage of patients having to get the balloon removed before the initial term. When you’re looking for a longer term option for weight loss, it may make sense to consider the Spatz, as the expected weight loss is good.
