The colon is the primary target of many functional and pathological disorders, which may have an acute or chronic presentation.
Over the past few years there has been considerable improvement in the diagnosis of patients with colonic troubles due to the improvement of the diagnostic tools of colorectal diseases.
There are many methods in diagnosing colorectal diseases as: occult blood testing in stool, Barium enema, colonoscopy and recently CT virtual colonoscopy which has several advantages of over conventional colonoscopy as: no sedation, minimally invasive procedure, visualization of the colon next to an obstructing lesion and ease of inspection of both antegrade and retrograde sides of haustral folds.
