New Test Using Swallowed Camera?
0

5 posts in this topic

My son, who works in investment banking, told me a few months ago about a company that had developed a mini-camera, the size of a pill, which could be swallowed. The camera would then work its way through the GI system, taking photos along the way. The manufacturer specifically talked about how useful it was in detecting Celiac Disease. I imagined it was in development, and might be available in a few years, but last week a friend told me that her gastroenterologist had used this new technology for some GI problems she was having. She talked about the camera and the need to make sure it exited the system (I didn't want to know HOW you would search!). Has anybody here had or heard about this new test yet?

If you do a google search for "camera pill" there is TONS of info out there on it. It is made by the company Given Diagnostic Imaging Systems. Here is one article on it:

FDA Talk Papers are prepared by the Press Office to guide FDA personnel in responding with consistency and accuracy to questions from the public on subjects of current interest. Talk Papers are subject to change as more information becomes available.

FDA CLEARS CAMERA PILL TO PHOTOGRAPH SMALL INTESTINE

FDA today cleared for marketing a swallowable capsule containing a tiny camera that snaps pictures twice a second as it glides through the small intestine.

The product represents a technological advance in methods of examining the gastrointestinal tract.

The device, made by Given Imaging Ltd., an Israeli company with North American headquarters in Norcross, Ga., is intended to visualize the inside of the small intestine to detect polyps, cancer, or causes of bleeding and anemia.

Currently the standard method of detecting abnormalities in the intestines is through endoscopic examination in which doctors advance a scope down into the small intestine via the mouth. However, these scopes are unable to reach through all of the 20-foot-long small intestine, and thus provide only a partial view of that part of the bowel.

The camera capsule is designed to take photos of the entire small intestine, enabling doctors to see areas that the endoscope cannot reach.

The device, called the Given Diagnostic Imaging System, comes in capsule form and contains a camera, lights, transmitter and batteries. The capsule has a clear end that allows the camera to view the lining of the small intestine.

The patient swallows the capsule, and the natural muscular waves of the digestive tract propel it forward through the stomach, into the small intestine, through the large intestine, and then out in the stool. The capsule transmits the images to a data recorder, which is worn on a belt around the patient's waist. The physician then transfers the stored data to a computer for processing and analysis.

The battery has an expected life of eight hours, which is generally long enough to photograph the small intestine, but not long enough to photograph the entire gastrointestinal tract.

FDA cleared the device based on both animal and clinical studies of safety and effectiveness conducted by the manufacturer. In one of the human trials, Given Imaging studied the use of the camera capsule in patients with suspected small intestine disease. All patients had signs of either unexplained chronic gastrointestinal blood loss or anemia. All had undergone standard endoscopic and radiological evaluations prior to receiving the capsule.

Study results showed that the camera pill was safe, without any side effects, and was able to detect abnormalities in the small intestine, including parts that cannot be reached by the endoscope.

FDA cleared the device for use along with--not as a replacement for--other endoscopic and radiological evaluations of the small bowel. The capsule was not studied in the large intestine.

The product is available by prescription only.

I have read where the test costs about 1200 dollars. I'm not sure how that compares to a traditional scope.

Here is a link to an article in which a photo of the device is shown http://www.detnews.com/2003/health/0311/30/a08-337857.htm

Camera pill takes doctors inside the digestive tract

Device helps diagnose intestinal problems that were a mystery before

DES MOINES, Iowa -- Doctors have used small cameras on snaking tubes for years to check patients' intestinal troubles. These days, they're asking some patients to swallow the entire camera.

Gulp.

With a single pill loaded with technology similar to a digital camera, doctors can view more than 50,000 still images captured during the trip through the final 20 feet of the small intestine that previously was visible only on X-rays.

The pill, known as the M2A Capsule Endoscopy, is about the size of a multivitamin and is swallowed with a sip of water.

The camera, encased in a white plastic capsule, takes pictures, which are transmitted on a radio frequency. The images are captured in a recording device worn on a belt around the patient's waist. After eight hours, the belt is turned over to the doctor.

The device is a "marvel of microelectronics," said Dr. David Ramkumar, a gastroenterologist at the University of Iowa Hospitals and Clinics, where patients since the beginning of the year have been swallowing the capsules to diagnose intestinal problems.

Hospitals and clinics around the country, in increasing numbers, have been using the technology since the Food and Drug Administration approved it in December 2001.

Seventy-one-year-old Ruth Brown wanted to know why she was suffering from persistent intestinal bleeding. Her doctors had probed her stomach and performed a colonoscopy, but were stumped.

They suggested the camera pill.

"I looked at it and said, 'Oh, doctor, I can't swallow that,' " Brown said. "A great big horse pill -- that's what it looked like."

Despite her worries, she swallowed it with a mouthful of ice water.

Patients fast for 10 hours before taking the pill, and are able to go about their days as long as they avoid strenuous activity. Brown was able to work her regular volunteer shift at a hospital.

For years, doctors used cameras on elongated flexible tubes to examine the upper portions of the digestive system and the colon. About 20 feet of the small intestine could not be reached with the endoscope so doctors would have patients swallow barium, then X-ray the area to look for trouble spots -- a test Ramkumar called unreliable.

Invasive surgery would be the next option if a disorder was diagnosed.

The tiny camera "provides a view of that middle portion of the digestive tract that we have not had previously," Ramkumar said.

The camera pill has been an effective way to diagnose unexplained bleeding, Crohn's disease, celiac disease and intestinal tumors. Ramkumar said the pill has been successful on patients who, like Brown, show clear evidence of intestinal bleeding, but in whose cases conventional tests have not turned up a cause.

Using the images retrieved by the camera, Ramkumar determined that Brown's persistent bleeding was caused by radiation burns in her small intestine left over from cancer treatment seven years earlier, and exacerbated by a prescription blood thinner.

"They've taken me off the blood thinner," Brown said, and since then her bleeding has been much less. Brown said the burns are so spotty that doctors decided it would be impossible to cut them all out, but the steps taken since the diagnosis have improved her health immeasurably.

Doctors at the University of Iowa Hospitals and Clinics expect to treat more than 150 patients with the camera pill by the end of the year, spokesman Tom Moore said.

The procedure costs about $1,200 at the hospital in Iowa City. Ramkumar said the pills are purchased directly from the manufacturer, Israel-based Given Imaging, for $450 each, a price included in the cost of the procedure.

At the University of Iowa Hospitals and Clinics, results so far have shown a 60 percent to 70 percent success rate in detecting abnormalities. That may seem low, but it is considerably better than old methods of detection, Ramkumar said.

The pill isn't 100 percent successful because, due to its small size, the camera can capture an image of only about 70 percent of the digestive tract at any one point, he said.

Still, "If you compare that with what we had before, we were looking at rates optimistically in the 30 to 40 percent range," Ramkumar said. "We're practically doubling our success."

Once the images are recorded and the camera belt is removed, the patient simply passes the pill.

"They aren't used again," Moore said.

Heard about it! I've done it!

Been having anemia (low iron) for quite some time. Docs were convinced that I was bleeding somewhere, which was lowering my iron stores. Swallowed the camera in December after already doing all kinds of other fun tests - small bowel follow through, endoscopy, gastroscopy, etc. The pictures lead the doctor to do a blood test for antibodies indicating Celiac, and they came back positive! Way positive!

Been on a gluten-free diet for 5 weeks now and just had a blood test this week to check my iron. It's almost back into the normal range! We'll do another antibody test in a few months to see where that's at.

The camera does work. The harness that you have to wear for the 8-hour test is the worst part - pretty uncomfortable. There is a small chance (about 1%, I think) of the camera getting stuck, causing a bowel obstruction. I had no problem.

Cost was about $1300.

Any more question - I'll try to help!

Tom,

Did your insurance company pay for the camera pill??

And did you need an intestinal biopsy afterwards to confirm the celiac diagnoses??

Thanks

Kris

Hi Kris

Insurance picked up almost all of the bill, except for my co-pay amount. The doctor's office checked with them first, just to make sure.

We didn't do a biopsy. Doctor felt that what he saw from the camera, along with the very positive blood test, was good enough.

Not sure I agreed with him on that, but the gluten-free diet seems to be working. I didn't present with all the classic sysptoms many CDers have - severe diarrhea, cramping,etc. The anemia was really my only symptom, and it is definitely improved.

Hope that helps!

Tom

    • I figured I would update those who were wondering.  I have gotten the appt. so far moved up to August 30. I am waiting to have gene testing done via swab for all 3 of my kiddos tomorrow. My daughters celiac antibodies came up negative but her IgA is low which the ped said could cause false negative antibodies for celiac so she will need to see a GI dr. also. The pediatrician is going to call the GI to try to get them in sooner. I am keeping them all on a gluten diet until the GI dr. decides what to do. I am on the cancellation list already for my son, however I am not going to be persistent with my phone calls to them until I have the results of the gene test. I really want that result in my hand before going to the GI dr if I can. Maybe if he is positive, along with his bloodwork and my history they can forgo the endoscopy. But he will eat gluten till then.  My husband and I have been very honest and upfront with him as to what is going on and the possibility of the endoscopy and what that entails and although scared in general he seems ok after assuring him that since I have it he has me to help him every step of the way.  Going through his current diet with him I realized that he is truly on such a low gluten diet that I am actually surprised his bloodwork shows antibodies at all!  So I told him to make a list of allllll the gluten he could possibly think of eating and he needs to pound it until the GI visit or endoscopy. Funny thing is everything he keeps thinking of to want to eat...is already gluten free!  The other night we were at a friends and he asked if he could be done with his hotdog. I made him finish just the bread 😂 Thanks for your help and advise and I will keep y'all posted on both kids!  My oldest is a ok as far as all his antibodies. Just actually had a follow up for other immune issues and all his levels are now normal!
    • I like your plan Cara, I may have to include it in my sons.    Poor little guy is still very very sick. I think he is resisting and cheating, despite having the support of two other siblings and a 100% gluten-free home. 
    • Despite it being a nightmare, I did wait for my kids to get biopsies. At one point I had one severely ill child gluten-free and two more waiting having to eat it. It was worth the wait though and I think long term a biopsy may be worthwhile, especially for school. I have already had issues with schools and camps so having a firm diagnosis has been helpful. 
    • Knowing that the reaction to gluten in celiacs is an uncalled for immune system reaction, I was thinking of how a cure would be possible. Maybe a medicine that somehow turns off the immune system. The only thing that i've heard do that... HIV.  obviously that's way worse than celiac. Just some food for thought.
    • Well, you can probably get an apple or something.  You might be able to get someone to boil you some eggs.  But be careful of things like nuts that should be naturally gluten free.  They have almost always been soaked in a flavor solution that usually containes caramel coloring, "soy" (wheat) sauce and other aditives.  If I am really hungry and must eat in a Chinese restaurant, I order plain white rice and steamed vegetables.  But even so, you must monitor it carefully.  The rice sometimes has other substances added to give it a better texture, and very often the vegetables have in fact had "just a little bit" of soy sauce added.  To be fair, celiac disease is hardly ever found in East Asians, so understandably people are not tuned it to it.  Also, culturally, with the exception of fruits, it is generally thought that the flavor of foods needs to be enhanced, so it is had to find anything natural even in the "western" gorceries. Even in the western restaurants, be careful.  Fish and meat and often vegetables are usually pre-marinated. I will not even attempt to address the issue of cross-comtamination, since that is a whole higher order of things. I do know what I am talking about; I have celiac and have worked here for nearly 7 years.
