PillCam

The American FDA has a rails record of sitting back and letting Europe guinea-hog medical innovations for u.s.a., especially durable goods. Many a spider web search has resulted in the familiar shutdown: "not available in America, although in common use in Europe." I myself accept participated in medical tourism for a durable implantable device that'southward been in apply in Europe since the mid-1980s, but nevertheless isn't bachelor stateside, for reasons beyond my ken.

One such device, which has settled into widespread use in Europe, but remains under provisional FDA oversight instead of outright approval, is the PillCam. You may have heard about the device a few years back, merely it'due south still hung up in the earth of "off-label" utilize. While the FDA has provisionally approved the PillCam for use, they only allow it after a patient has experienced an unsuccessful endoscopy or colonoscopy.

Here's how it works. At that place are iii versions of the device: the PillCam ESO, for the esophagus, the PillCam SB for the breadbasket, and the PillCam Colon for the lower GI tract. All versions of the PillCam contain a little chemic battery that'll give it eight to x hours of recording time, plus a lite source and two tiny CCD cameras. A patient who'south about to utilise it volition strap on a belt containing a receiver and an SD bill of fare or equivalent storage medium. Then they swallow the tiny pill.

The camera gain through the GI tract, takes between 2,600 and 57,000 pictures while it'south on its way through, and "produces no pain or even sensation equally it moves through the colon" over a period of a few hours. After it's taken all the close-ups and beauty shots it tin can, the thankfully dispensable PillCam winds up flushed down the toilet within about 72 hours. But the photos are on the SD menu, ready for medical examination.

Given the mostly extremely unpleasant experience of having a colonoscopy or endoscopy, it'southward a major perk that the patient feels aught at all during this procedure. According to a study published in the New England Journal of Medicine, there were no serious adverse events among 320 subjects given the PillCam Colon. The report concluded that use of the PillCam was "a safety method of visualizing the colonic mucosa through colon fluids without the need for sedation or insufflation." Later on feedback from clinics using the PillCam pointed out that some patients insisted on having 10-rays to prove that they'd actually passed the photographic camera, considering they never felt a thing.

This is exactly what doesn't happen.

There are still a few drawbacks. The PillCam isn't as good at diagnosing polyps as a traditional colonoscopy, but it has the advantage of being able to reach the 15-20 feet of small intestine that colonoscopy just tin can't run into. It likewise tends to go hung upward if a patient already has a bowel obstruction or another obstructing GI condition like polyps or diverticulosis. Information technology tin't supplant the colonoscopy, only it certain tin can offer an offshoot therapy that isn't near as uncomfortable.

Too, the PillCam ESO doesn't image the stomach, so information technology can't really catch signs of peptic ulcers. For that, an endoscope is still the right approach, because information technology allows the physician administering the endoscopy to also take a biopsy. Having the PillCam catch a picture of a possible ulcer would just mean the person would have to go through an endoscopy subsequently anyway. Bummer. (This is office of why the FDA hasn't approved information technology as a first-line diagnostic method.)

But the PillCam ESO's ability to thoroughly image the upper GI tract without patient discomfort is unparalleled. It can catch problems in the esophagus, like signs of the chronic acid reflux damage that can contribute to GERD.

And this capture-all-the-data approach lends itself well to reckoner-aided diagnostics. Auto learning is making great strides in identifying subtle but important conditions in skin cancer, for case — and skin is made of epithelial tissue, just similar the membranes lining the GI tract. This suggests an area of diagnostics that's ready for some AI to sink its digital teeth into the problem. Hey, Watson — doing anything this weekend?
