[Colorectal neoplasms. Study of the attitudes among Danish gastroenterologists].

The results of a questionnaire concerning colorectal neoplasms are discussed with reference to the relevant literature. Coloscopy is the examination of first choice in the diagnosis and follow-up of colorectal neoplasms but double-contrast barium enema (DCBE) is still justified, particularly in cases where coloscopy proves difficult. In the light of present knowledge, the replies to the questionnaire appear to attach too much importance to frequent early control examinations of patients with cancer and adenomata at the expense of more relevant long-term control. Before a control programme for colorectal neoplasm is commenced, a clean colon should be ensured. Patients attending control examinations should be informed about the symptoms of interval cancer.
