We’re all mature medical professionals here, but as the resident engineer, this particular Medgadgeteer never had the unique opportunity to learn of all the horrible things that can go wrong in one’s series of tubes (GI tract).
In searching the New England Journal of Medicine for the AED post, we came across the monster you see pictured above. A still colonoscopy picture of a 20cm worm is one thing, but the NEJM and authors Jang and Lee gave us the treat of watching it writhe around on video.
You’ll note the medgadget lasso-thing coming to the rescue near the end of the video (if you can stand to watch the whole thing).
