Scientists develop remote-controlled pill-shaped camera to diagnose digestive issues
but they’re severely limited and not controllable by physicians, relying entirely on gravity and the digestive system for movement.
“A traditional endoscopy is an invasive procedure for patients, not to mention it is costly due to the need for anesthesia and time off work,” Andrew Meltzer, a professor of Emergency Medicine at the GW School of Medicine & Health Sciences, said. “Magnetically controlled capsules could be used as a quick and easy way to screen for health problems in the upper GI tract such as ulcers or stomach cancer.
This technology is still in the testing phase though results have been positive. Meltzer and colleagues at medical technology company AnX Robotica conducted a 40-person study and found that doctors could accurately control the capsule to all major parts of the stomach with a 95 percent rate of successful visualization. These patients also underwent a traditional endoscopy to confirm that the camera didn’t miss any high-risk lesions.
