[Radiology and endoscopy in the diagnosis of colorectal cancer].

Over a 5-year period, 64 patients with a primary colorectal carcinoma were studied by means of radiographic or endoscopic diagnostic techniques. The overall accuracy rates of the barium contrast enema and endoscopy were 86% and 93%, respectively. A comparison of diagnostic accuracy between radiology and endoscopy yield a 75% correlation rate. Whenever possible, both radiology and digestive endoscopy should be carried out to assess the diagnosis of colorectal carcinoma.
