QUARANTA, Andrés J.; BURGOS, Lucrecia; SASIA, Fabricio  and  VILLAVICENCIO, Roberto L.. Extracolonic findings in virtual colonoscopy studies. Rev. argent. radiol. [online]. 2011, vol.75, n.2, pp.103-113. ISSN 1852-9992.

Purpose. Analize the presence and type of extra-colonic findings (ECF) in virtual colonoscopy (VC) exams and evaluate the behavior after the diagnosis. Materials and Methods. 100 VC exams were retrospectively analyzed in search of ECF regardless of the outcome of the VC. The study population consisted of 62 women and 38 men with an average age of 63. The purpose of the exam included asymptomatic patients for screening as well as patients with apparent diagnosis of neoplasm pathology and cases which came with incomplete optical colonoscopies. The studies were carried out with a Philips Brilliance of 64 detector rows with specific protocol for VC. All patients received bowel cleansing and barium-based fecal tagging. The ECF were categorized as being of low, moderate or high importance. The findings of low or no importance are those benign alterations or those alterations that are unlikely to require further examination. Moderate importance ECF are defined as alterations that do not require immediate treatment but that will probably need investigation or treatment later. High importance ECF involve significant alterations that require surgical treatment, medical intervention or new tests in short term. Results. Out of 100 patients, 66 presented ECF. In total there were 122 ECF that were distributed as follows, 61% of low importance, 26% of moderate importance and 13% of high importance. Conclusions. Extracolonic evaluation needs to be handled with extreme care and judgement by the physician who interprets the study and also by the one who receives it. It is crucial to place ECF in the general context of the patient.
