Gastroenterology podcast #1
Dr. David Leaverman goes into the serrated legions within the colon. He basically describes a study he took in mid 1990’s about the polyps that are the primary tumors or growths that result in colon cancer. He was looking for the possible causes that serrated polyps lead to cancer. He tested up to 3000 individuals over the course of five years in order to get approximate data for the study. He was originally trying to prove that neoplasia was associated with the serrated polyps that were detected during a colonoscopy. Neoplasia (new growth in Greek) is the abnormal proliferation of cells. The growth of the cells exceeds, and is uncoordinated with that of the normal tissues around it. The growth persists in the same excessive manner even after cessation of the stimuli, usually causing a tumor.
He conducted this study at thirteen medical centers around the U.S. using colonoscopy as the golden standard and found that ten percent of the patients (who were between the ages of fifty and seventy five) had a form of advanced neoplasia that would have been missed if colonoscopy had not been used as the means of testing. This showed that serrated polyps and hyper plastic polyps (which are a form of polyps with a narrower base) increased the risk of developing cancer within the colon. The overall test showed that if patients had the proximal nondisplastic serrated polyps in the proximal colon than they had a twofold chance of developing advance neoplasia. The second take away is that during the examination, doctors have to be specifically mindful of where to locate the legions that could me hidden within mucus or the base of the colon during colonoscopy.

Gastroenterology Podcast #2
Dr David Katzka talks about a disease known as Achalasia that has been inflicted upon humans for quite some time. The ailment is somewhat of a mystery because we do not understand its pathophysiology. However, new information about the disease has been discovered within the past twenty years. For example we now know that this is an auto immune disease based of research that tested the antibodies directed aganst the miatary plexus in patients with the disease. One of the great strides in the field of gastroenterology is the mastery of and its related subjects. To hear the entire podcast, click here.

Dr James Allison goes into detail in his long-term guidelines for colorectal cancer screening tests and how evidence and transparency make for large parts of any colonoscopy. He finds that there were improvements in the fecal blood tests in order to detect possible cancers within the colon. He originally wrote his perspective based off of the test results he took during he 1990’s and found that through colonoscopy, many of the early warning signs such as polyps and bleeding can be detected through colonoscopy that doctors previously thought were not stable enough to rely solely on colonoscopy.
