To verify the knowledge and the interest on CT Colonography of the General Practionners of a big city.

On February 2014 a web-based Survey on CT Colonography was administered to all the 1,050 General Practionners of our town. The initial survey was written and reviewed by the co-investigators and consisted of the 10 following multiple choice questions. 1.CTC is a CT of the abdomen aimed at the study of the colon, properly distended with air or carbon dioxide insufflated through a rectal catheter. Information already known? 2. CTC is a low radiation dose examination, comparable to that absorbed from the environment in a year. Information already known? 3. The most recent data indicate that the accuracy of CTC in the diagnosis of polyps and carcinomas is similar to that of the traditional OC. Information already known? 4. The most recent data indicate that the CTC accuracy in the diagnosis of polyps and carcinomas is higher than that of the traditional DCBE. Information already known? 5. Do you think that CTC may represent an effective technique for CRC screening? 6. In a patient with incomplete OC or who refuse OC, which of the following options would you choose? Video capsule or CTC or DCBE 7. In a patient with FOBT positive, with OC is incomplete or refuse OC, which of the following options would you choose? Video capsule or CTC or DCBE 8. In the case of a patient diagnosed with CTC a polyp 10 mm, what would be your advice: 9. On behalf of your patients are required prescription of virtual colonoscopy? 10. Are you interested in attending a formative event on this topic?

Finally 231/1050 (22%) completed the Survey. 95% of responders are interested in attending a formative event on CTC. Only 57% of responders is aware that CTC is a low dose technique. Only 48% is aware that CTC and OC accuracies in diagnosing colonic polyps and CRC are almost the same, and 30% of responders don’t know that CTC accuracy is highly superior versus double contrast barium enema accuracy. 93% of responders advises immediate OC in patients diagnosed with a 10 mm polyp.

About 95% of our Physicians demonstrated interest in CT colonography asking for a one-day event on this topic. Some important CTC aspects are not well known yet.

This survey has highlighted the need for education of General Practionners on the latest capabilities and limitations of CTC
