This robotic pill will replace endoscopies  

No more pain and anesthesia

Endoscopic capsules for monitoring the inside of our bodies have been around for a while, but they rely on gravity and our digestive system for movement, limiting control by the doctor. Now, the GW School of Medicine & Health Services has introduced NaviCam, a pill-shaped camera that allows a doctor to track its movement inside our body to photograph potential problem areas.

NaviCam has the potential to replace traditional endoscopy, removing patient discomfort and the need for anesthesia. For movement, it uses external magnets and joysticks in the style of video games.

Traditional endoscopy is an invasive process for patients, not to mention costly due to the use of anesthesia and the time required. Magnetically controlled capsules can be used as an easy and quick way to detect health problems such as ulcers and stomach cancer. – Andrew Meltzer, Professor of Emergency Medicine

The technology is still in the testing phase and the first results are encouraging. A study of 40 patients proved that doctors can accurately control the capsule in all major parts of the stomach with a 95% imaging success. Patients also underwent a traditional endoscopy to confirm that the camera-pill did not miss a spot.

The camera can detect bleeding, inflammation and lesions, and can automatically transmit video and photos for further examination. Subsequent trials will include a much larger number of patients.
