Postpolypectomy coagulation syndrome (Postpolypectomy syndrome or PPCS) is a condition that occurs following colonoscopy with electrocautery polypectomy, which results in a burn injury to the wall of the gastrointestinal tract. The condition results in abdominal pain, fever, elevated white blood cell count and elevated serum C-reactive protein.
Sovaria states as at 1998 that "colonoscopy, as opposed to sigmoidoscopy, should be advised for endoscopic surveillance, because of the right-side location of colorectal adenomas; UGI endoscopic surveillance is warranted in an attempt to detect premalignant gastric or duodenal tumors; individuals affected with [attenuated FAP] may require total ...
Several SSLs confer a higher risk of subsequently finding colorectal cancer and warrant more frequent surveillance. The surveillance guidelines are the same as for other colonic adenomas . The surveillance interval is dependent on (1) the number of adenomas, (2) the size of the adenomas, and (3) the presence of high-grade microscopic features.
Unexplained anemia (usually along with a colonoscopy) Upper gastrointestinal bleeding as evidenced by hematemesis or melena; Persistent dyspepsia in patients over the age of 45 years; Heartburn and chronic acid reflux – this can lead to a precancerous lesion called Barrett's esophagus; Persistent emesis – vomiting; Dysphagia – difficulty ...
Some medical societies in the US recommend a screening colonoscopy every 10 years beginning at age 50 for adults without increased risk for colorectal cancer. [25] Research shows that the risk of cancer is low for 10 years if a high-quality colonoscopy does not detect cancer, so tests for this purpose are indicated every ten years. [25] [26]
Traditional serrated adenoma seen under microscopy with H&E stain, showing serrated crypts. SPS may occur with one of two phenotypes: distal or proximal. [6] The distal phenotype may demonstrate numerous small polyps in the distal colon and rectum, whereas the proximal phenotype may be characterized by relatively fewer, but larger polyps in the proximal colon (cecum, ascending colon, etc.). [6]
Once an adenomatous polyp is identified during colonoscopy, there are several methods of removal, including using a snare or a heating device. [22] Colonoscopies are preferred over sigmoidoscopies because they allow the examination of the entire colon and can detect polyps in the upper colon, where more than half of polyps occur.
Virtual colonoscopy (VC, also called CT colonography or CT pneumocolon) is the use of CT scanning or magnetic resonance imaging (MRI) to produce two- and three-dimensional images of the colon (large intestine), from the lowest part, the rectum, to the lower end of the small intestine, and to display the images on an electronic display device.
