He’s had countless interests over the course of his career as a gastroenterologist and professor at the University of Massachusetts Medical School, but Dr. David Cave’s most current interest is an approach in gastroenterology called video capsule endoscopy. This procedure involves a pill not much larger than a pill of aspirin that has the capability of taking pictures all throughout the gastrointestinal (GI) tract. By providing an unprecedented way of looking at the GI tract, this technology has resulted in a treasure trove of new, incredibly useful diagnostic information. Dr. Cave was the first in the U.S. to utilize this technology and was the only one using it for over a year since the first device was introduced in 2001.   He joins the podcast today to discuss how the technology had advanced and evolved over the years, the information that’s been discovered as a result of this technology, the recent development of a magnetically controlled capsule, the possibility of using artificial intelligence in reading the images captured by these capsules, the results of a randomized controlled trial that compared capsule endoscopy with the standard of care in detecting active bleeding in patients, and so much more.
