While the story notes that the U.S. price of the Obalon intragastric balloon has yet to be announced, the story could have reported that the device and related care typically cost $2,500 to $4,000 in Europe, where it has been available for almost three years. Costs are also likely markedly higher than working with a behavioral team. The story quantified benefits by stating: Obese patients who swallowed balloon capsules that helped them eat less lost an average of 15 pounds, roughly two times more weight than patients who just dieted and exercised, researchers report. and: People treated with the balloons lost an average of 7 percent of their weight, compared to less than 4 percent for those who received the sham device, the researchers found. Six months after the balloons were removed, nearly 90 percent maintained the weight loss they achieved during treatment, Pryor said. In addition to reporting the weight loss results announced by researchers and that, unlike other balloons, this device doesn't require patients to be sedated during placement, the story adds important context by including comments from independent sources who are skeptical that many patients will maintain their lower weight long after the device is removed. The story mentions these harms: As for side effects, one patient had a bleeding stomach ulcer while taking high doses of pain pills after a knee replacement. Most patients (91 percent) suffered from stomach cramps and nausea, which nearly 100 percent said were mild or moderate. The story would have been stronger if it had warned readers that a study that puts a device in only a couple of hundred people may miss problems that could appear after the device is placed in hundreds of thousands or even millions of patients. The documentation that the manufacturer will give patients lists several serious, even life-threatening, potential side effects, including intestinal and airway blockages. These potential risks should have been noted. The story reports the key features of the trial. It also notes that, "Research presented at meetings is considered preliminary until published in a peer-reviewed journal." The story would have been stronger if it clearly reported that the trial does not provide any evidence about whether the Obalon device is any better or worse than other options, because it did not compare it to similar balloons or to other weight loss interventions, other than the lifestyle counseling offered to all study participants. The researcher quoted in the story notes that this device could be an option for people who are leery of surgery. Independent sources quoted in the story predict a small role for such devices. One of the strongest aspects of this story is the ample use of independent sources to provide context and point out limitations of the device. However, this criterion demands that sponsors of research be identified, and this story does not tell readers that the trial was sponsored by Obalon Therapeutics. The story includes discussion of weight loss surgery and lifestyle interventions. It includes a quote noting that the Obalon device does not require patients to be sedated during insertion, which implies there are other similar balloon devices, though the story would have been better if it specifically noted that there are already two very similar devices available in the U.S. as well as other balloon devices that are for sale in other countries. It also could have pointed out that these results don't appear more effective than an intensivebehavioral program. The story reports that the Obalon balloon was approved by the FDA in September and will be available in January 2017. As noted above, the story reports that the Obalon device does not require patients to be sedated during insertion, which appears to be the main difference between this device and other similar balloons. It would have been better if it had more clearly informed readers that there are other intragastric balloon devices already on the market. The story notes that these study results also werepresented back in May. The story includes several quotes from independent sources, as well as important details that were not included in a news release from the organizers of the the medical meeting where these results were presented.
