Since polyps often take 10 to 15 years to transform into cancer in someone at average risk of colorectal cancer, guidelines recommend 10 years after a normal screening colonoscopy before the next colonoscopy. (This interval does not apply to people at high risk of colorectal cancer or those who experience symptoms of the disease.) [28] [29]
SCAD is diagnosed via colonoscopy, often incidentally during examination for unrelated concerns. Colonoscopy shows erythema of the colonic mucosa, which may be characterized by friability and exudate. [1] The descending and sigmoid colon are typically involved. Biopsies of the affected area and the unaffected rectum confirm the diagnosis. [1]
Barium enema is inferior to colonoscopy in terms of image quality and is usually only performed if the patient has strictures or an excessively tortuous sigmoid colon where colonoscopy is difficult or dangerous. Colonoscopy will show the diverticulum and rule out malignancy. A colonoscopy should be performed 4–6 weeks after an acute episode.
A colonoscopy is a routine medical procedure that could save your life, but if you think that you don’t have to worry about getting one until you’re 50 then think again (hint: new guidelines ...
The signs and symptoms of colorectal cancer depend on the location of the tumor in the bowel, and whether it has spread elsewhere in the body ().The classic warning signs include: worsening constipation, blood in the stool, decrease in stool caliber (thickness), loss of appetite, loss of weight, and nausea or vomiting in someone over 50 years old.

PPCS may resemble perforation. Recognition of PPCS is important, since treatment usually does not require surgery, unlike gastrointestinal perforation. Laboratory studies may show elevated white blood cell count (leukocytosis) and elevated inflammatory markers such as C-reactive protein. CT scan of the abdomen may show severe mural thickening ...
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.
