To map the view of surgeons on the role played by computed tomography colonography (CTC).

An electronic questionnaire was sent to members of the Brazilian College of Surgeons. The questionnaire consisted of 16 multiple-choice questions about demographics and general knowledge about CTC.

The authors obtained 144 responses; 90.3% of the specialists were men, 60% with less than 30 years from graduation, 77.1% were gastrointestinal surgeons, 22.9% were general surgeons, 53.5% were involved in academic activity, and 59.7% had their professional activity in cities with more than 500,000 inhabitants. As regards the knowledge about CTC, 84.7% of the respondents knew the method, 70.8% knew how it is performed, 56.9% reported knowing the bowel preparation used for the procedure, 31.3% used the method, and 53.5% knew some CTC service in their city. About half of the respondents did not know the precise indication of the method. The method is most frequently known and used by professionals working in cities with more than 500,000 inhabitants (p < 0.005). There was a tendency of a more frequent use of the method by the professionals pursuing an academic career.

Despite its infrequent use in Brazil, CTC is a well known method, particularly in large urban centers and in the academic environment.
