New "Endoscope On a Pill" 96

ScienceDaily is reporting that a new form of endoscope developed at the University of Washington is more like swallowing a pill than the typical "massive" cable. The pill, complete with a 1.4 mm wide tether, contains a single optical fiber for illumination and six fibers for collecting light. "Once swallowed, an electric current flowing through the UW endoscope causes the fiber to bounce back and forth so that its lone electronic eye sees the whole scene, one pixel at a time. At the same time the fiber spins and its tip projects red, green and blue laser light. The image processing then combines all this information to create a two-dimensional color picture."

    I distinctly remember seeing a story about something like this on the Canadian TV show Daily Planet over a year ago. Our host, Jay Ingram, demonstrated it by actually swallowing the pill, and they showed the video on national TV.

    I'd post the link, but this doesn't exactly sound like new stuff and I'm at work so I can't do the research. This was back when he was still co-hosting with Natasha Stilwell, which places it between 2004-2006. She's been replaced in the 2006-2007 season.

      Yes, what you're describing is actually in clinical practice fairly routinely now. From what I can tell without actually reading the article, these are serving slightly different purposes.

      The pill with the camera (what you saw) is for looking at the bowel. It will not spend any significant time in the esophagus. It takes pictures as it travels through your bowel. AFAIK, it requires a bowel prep (drinking a bunch of nasty clear fluid for several hours) or the pictures will be full of crap, just like a

    Right now, an endoscope requires a general anesthesia, which requires the patient to be monitored for adverse reactions, as well as accompaniment since the patient won't be able/allowed to drive home afterward.

    My mom just had one done a few days ago, and she lives alone. The clinic performing it usually has a shuttle to pick up and drop off patients, but it wasn't available that day. She offered to take a cab, but they wouldn't allow it, stating that whoever is picking her up and dropping her off would have to stay there. Luckily, a neighbor was willing to help. (I live a few states away, for those wondering why I wasn't helping her.)

    If he wasn't able to help her, she'd have had to reschedule, which would have meant rearranging her work schedule and possibly losing pay if she can't arrange the time off on short notice. If she could have driven herself there and back, she could have scheduled it around work, instead of the other way around.

    I wonder how many people aren't able to have procedures like this done because they don't have the time/resources.

    • Right now, an endoscope requires a general anesthesia, which requires the patient to be monitored for adverse reactions, as well as accompaniment since the patient won't be able/allowed to drive home afterward.

      No, it doesn't, I had one done last year without the general, only anesthetic I used was a tongue numbing mouth wash. It really wasn't that unpleasant. The doctor didn't want to do it, but I told him that I wasn't willing to undergo superfluous anesthesia just for something as trivial as an endoscopy. I bolstered my position by coming alone without anybody to drive me home.

      The charges that it's painful or uncomfortable are really over blown. The only people who should take the knock out drugs are those wit

    • About 1.5 years ago I agreed to be a test subject for this procedure. I was going to have endoscopy the old fashioned way and they wanted to compare results. I wore a wide belt that contained the receiver and other hardware. The pill was clear with a camera in both ends so they could see coming and going. It was a large pill but easy enough to swallow with a little water. After ingesting the pill they had me slowly sit up. The whole deal took about 20 min. No discomfort at all. No drugs needed!

    • I've had several endoscopies and never under general anesthesia. Normally it's a local anesthetic sprayed onto the back of my throat with an IV benzo, and sometimes Fentanyl as well. They have a look around and often take biopsies. I'm sure there are cases where general anesthesia is needed in endoscopies (medically, or because the patient doesn't tolerate the procedure), but I don't think it's "standard" from what I've gathered (in NZ, at least). Although, I'm still not allowed to drive home.
    • I can assure you that endoscopes DO NOT require general anesthesia. Typically the GI doctor will give you some benzodiazapenes and narcotics to put you in "la la land" so to speak but you are fully arousable albeit confused. This is how things are in the United States. In some other countries, they do not give you any medication and you have to take it like a man.

      For a first examination / diagnosis, you're right, at least in relation to cancer. No matter how good camera pills and MRI get, it will always be worthy to do the traditional exams, as suspicious tissues can be directly taken and polyps removed. However, this might prove adequate for regular check ups - it sure would help many people who have to do one every x years.

    I had a really bad hemorriod. I mean it was BAD. My then-wife finally talked me into taking it to the doctor. He scheduled a visit to a local hospital for an endoscopy, as he worried that the anal bleeding was from cancer.

    Well, to make a short story even shorter, the lady doctor he sent me to shoved a big (compared to today) TV camera up my ass. I didn't like it a bit; I'd never had anything up there but shit before. She told me I had the most beautiful colin she'd seen (flattery will get you nowhere in that situation, lady).

    So I went to see a proctologist. The office was dingy, and suggested dirtiness. The heavily accented doctor didn't inspire confidence, telling me I had the worst hemmoroid he'd ever seen. Not exactly what you want to hear from a doctor. "Has anyone ever died from a hemmoroid?" I asked. "No, not that I'm aware of" he said. "Has anyone ever died from hemmoroid surgery?" I asked. "Well," he answered, "there are always risks to any surgery".

    I suffered with my hemmoroid for another fifteen years after that, and finally let a different doctor (a very pretty lady too) cut me a new asshole about five years ago. I think I journaled it in the old Paxil Diaries, I'm not sure. While I was unconscience they did another endoscope, most likely with a much smaller camera.

    I was supposed to go back for another endoscopy last year. Guess what? I'd rather have colin cancer than have that damned TV camera shoved up my ass again!

      Trust me, the pain from a large mass in your colon is much worse than the pain from a colonoscopy. The pain doesn't go away and will leave you doubled over almost continuously. Then to get rid of the pain they have to cut out part of your colon, which is more painful than the mass was. To make matters worse you still need a colonoscopy before they'll schedule the surgery. Thankfully my mass was benign, but my grandmother's sized mass was malignant. As much as I hate my five year screenings, they're st

    In that you only need a trained clinician (say even a nurse) with training in the procedure, and could use this in any office, thus allowing screening in small towns as part of a visiting nurse program for screening, which would even further reduce the cost from the current device limitations that require anesthesia to use (which always has a risk).

    Besides, say it got lost, the small filament size (1.4 mm) would allow it to exit through the digestive tract and be recollected.
  • The last time I had to do this the doctor gave me a general anesthetic so I wasn't all the way out, but I wasn't able to get up either. He shoves this thing down my throat and keeps moving it, and every time he'd move it I was gagging on it. He keeps saying "just relax" yeah right, let me shove this thing down your throat and see you relax. Putz. Not only that my throat was sore for a week afterwords. I like the idea of this pill much better. Now if only my HMO would use it within the next 20 years.
    • I'd try another doctor. I've had several endoscopies in the last few years in an NZ public hospital and they have all been quite tolerable, with the worst part being the taste of the local anesthetic spray. I also had IV midazolam and fentanyl to help -- no general anesthetic. My throat is usually a bit sore for a few hours -- if that. It could also be that your medical condition (if there is one) made it more uncomfortable.
