A novel capsule to replace colonoscopy
Every year millions of people undergo colonoscopy or other colon investigations. Optical colonoscopy is currently the diagnostic gold standard for colon-related disease but its invasive nature puts patients at risk and limits its utilisation. Video endoscopic capsules (VCE) constitute a new solution to colonoscopy procedures. They could explore the gastrointestinal tract with higher diagnostic accuracy. However, it would be desirable to control their movement and limit the duration of the diagnostic procedure. Scientists on the EU-funded SUPCAM (New cost effective and minimally invasive endoscopic device able to investigate the colonic mucosa, ensuring a high level of navigation accuracy and enhanced diagnostic capabilities) project set out to develop an innovative active VCE (AVCE) that can be safely and accurately guided along the colonic lumen using an electromagnetic approach. AVCE design comprises a biocompatible outer part and an inner part that contains an image-capturing system, a data-transmitting-receiving system and a magnet. Guiding of AVCE occurs wirelessly through an external electromagnetic system. Image processing provides three-dimensional post-operative tissue reconstruction and lesion evaluation. Five-year survival from colorectal cancer is greater than 90 % if caught early. AVCE implementation should reduce clinical risk and patient discomfort while improving colorectal cancer detection and patient prognosis. Equally importantly, colorectal cancer patients would be more likely to adhere to their screening programs.
