So, some of you have probably found in your email the link to the knowledge challenge, but you can scan this QR code, and it'll bring you to the arcade game to answer the 15 questions we have. Go ahead and take a few minutes, and I'll wait until I see that everybody's had a chance to finish it. The top two scores are going to receive prizes. Yep, yep, we're giving you 15 minutes right about now. Okay, so our first question in the knowledge challenge was from the esophagus and stomach, and the question was, the esophagus moves food from the mouth to the stomach, is A. B. begins digesting proteins and fats in the food before arriving in the stomach, and C. is normally lined by the same columnar mucosa similar to the rest of the GI tract, and D. is A, B, and C. So, what was the right answer here? A. Correct. Okay. Obviously, the esophagus is lined by squamous mucosa, and there's really not a lot of digestion or breakdown of products, especially proteins and fats, that occurs in the esophagus, and so really its main function that's outlined there is moving food from the mouth to the stomach. Okay, same area of the digestive tract. The esophagus is where Barrett's mucosa occurs, B. is lined by squamous mucosa that can be damaged by acid exposure, C. has an inner circular and an outer longitudinal muscle layer responsible for propelling food through peristalsis, or D. A, B, and C. D. is in dog, correct. Oh, sounds like we got a winner out there. All right, now from the stomach, A. is the main location of fluid and electrolyte absorption, B. is the main location of nutrient absorption, C. is where food is ground down into small pieces to increase digestive and absorptive surface area, and D. is where gluten causes inflammation in patients with celiac disease. C is in Charlie, excellent. Next, question number four, which of the following is a cause of bleeding peptic ulcers? Is it A, helicobacter pylori, B, acetaminophen, C, celiac disease, or D, proton pump inhibitors? A. And the other main cause of ulcers? Non-steroidal anti-inflammatory drugs. Excellent. Okay, small and large intestine Crohn's disease is associated with A. inflammation limited to the colon, B. deep ulcerations and fistula formation anywhere in the GI tract, C. a normal appearing colon but inflammation seen under the microscope, or D. improvement on a gluten-free diet. Okay, B is as in boy, and that is the correct answer, excellent. And from the liver, gallbladder, and pancreas, the liver is important for all of the following except... Oh, you didn't even let me read them out. Answer is, in fact, E. Where's the insulin coming from? The pancreas, right, and all those other functions are part of functions of the liver. Okay, upper GI endoscopes and colonoscopes generally have the same dials to control scope tip deflection. Is that true or false? True. Good. In most GI endoscopes, optical fibers and electric signals from digital chips are used to carry both light to the scope tip and images to the image processor and monitor. Is that true or false? True. Correct answer. Okay, from the esophagus and stomach again, esophageal disorders can result in A. maldigestion, B. difficulty swallowing, C. chest pain, or D. both B and C. So answer is, D is in dog, correct. Again, from the esophagus and stomach, the initial treatment of bleeding peptic ulcers includes all of the following except proton pump inhibitors is A, B is gastrectomy, surgical removal of a portion of the stomach, C is upper GI endoscopy, and D is IV fluids. All of the above except B, gastrectomy. We certainly used to use that quite a bit, but it's certainly not part of the initial treatment of bleeding peptic ulcers. Small intestine. What type of endoscope can be used to view at least part of the small intestine? Is it A, a gastroscope, an upper GI endoscope, an entroscope, a colonoscope, or all of the above? The answer is D, all of the above. So a colonoscope can look at the terminal ilium, and we also can sometimes use a colonoscope to do a portion of enteroscopy or a little bit longer scope. So large intestine. Diverticulosis is associated with an increased risk of A, lower GI bleeding, B, colon cancer, C, ulcerative colitis, or D, appendicitis. A, lower GI bleeding, excellent. A, from the practice of gastroenterology, gastroenterologists commonly perform all of the following services except an appendectomy, a colonoscopy, prescribed biologic medicines for inflammatory bowel disease, upper GI endoscopy, or esophageal motility testing. A, surgeons do appendectomies. From inflammatory bowel disease, Crohn's disease can cause ulcers or fistulas in A, the colon, B, the small intestine, C, the colon and small intestine, and D, the colon, the small intestine, and the perianal area. Okay, the answer is D, as in David. The colon, small intestine, and perianal area is where ulcers and fistulas certainly occur in Crohn's. From large intestine irritable bowel syndrome, A can cause ulcers in the colon, B can cause abdominal pain, C can cause ulcers in the small intestine, or D, all of the above. B as in boy is the correct answer. Okay, that's it.
