title: [The role of colonoscopy in screening for tumors of the large intestine].
abstract: In 1986-1988, 6434 patients underwent colonoscopy in general hospital: 2076 were at risk for large bowel cancer whereas in 4358 the procedure was used for prophylaxis. Benign polyps or polyposis were detected in a total of 1699 (26.4%) patients: 856 (41.2%) in the risk group and 843 (19.3%) in the prophylactic one. Malignancy was diagnosed in 248 (11.9%) and 41 (0.9%) patients, respectively. It was found that small and early tumors made up 22% of the total number of cancers in the prophylactic group and 16.9% in the high risk group only. Colonoscopic screening carried out under general hospital condition is psychologically and economically justified since it allows to form a risk group and diagnose early cancer whereas timely removal of polyps assures secondary prophylaxis of large bowel cancer.
