Video-colonoscopy through a little camera introduced into a capsule certainly represents a less invasive method than traditional colonoscopy to reveal colic lesions, so the procedure is more and more improved in order to avoid false negatives due to tool defects. A video camera has been recently used, with an automatic stand-by in order to specifically display colon and it has been tested in a prospective, international trial, sponsored by pharmaceutical industry, performed on 328 patients averagely 59.

CT colonography, inappropriately defined by someone as “virtual colonoscopy”, has been, up to now, evaluated as a screening means in trials concerning above all populations with a high risk of intestinal cancer. In this European trial, 937 subjects with a high risk for tumours (family history for colorectal cancer, personal history of colorectal adenomas, positive occult blood test) have undergone CT colono-graphy followed, in the same day, by colonoscopy; endoscopists performed endoscopy in blind, which was abolished only in case of results contrasting with CT and endoscopy. The searched main outcome was the presence of an adenoma of at least 6 mm of diameter, with suspected characteristics. Compared with colonoscopy, CT colonography presented a positive predictive value of 62% and a negative pre-dictive value of 96%.

While technology has grown in leaps and bounds in recent years, doctors at Baylor College of Medicine recommend sticking to traditional methods when screening for colon cancer for now. The option for a "virtual" colonoscopy is now available. Virtual colonoscopy is a CT scan image of the colon and does not require the use of an endoscope – a thin, flexible device that is inserted into the colon.

Many in the US cancer prevention community thought the recent accumulation of data showing the effectiveness of computed tomography (CT) colonography, or virtual colonoscopy, as a screening tool for colorectal cancer would be enough to ensure that the procedure would be covered under Medicare. But they were wrong.

It is not clear yet what is the ideal follow-up in those patients in whom a screening colonoscopy has identified the presence of adenomatous polyps, also because the following control is often depending on the polyp’s characteristics.
