Abstract

Colonoscopy is a golden standard in the diagnostics of intraluminal diseases of the large intestine. Its advantage is the possibility of histological sampling (biopsy) and therapeutical interventions. In case of technical difficulties (stenosis, severe inflammation, diverticulosis, anatomical alterations) or lack of informed consent of the patient double contrast colonography is the routine diagnostic tool for the examination of the entire large intestine. The spread of the use of colon capsule as a novelty is keeping us waiting. A very important criteria is the adjudication of the expansion of the intestinal disease to the surrounding and distant organs. The correct diagnostics are the base of therapy planning. CT colonography as a standardizable imaging method can give information at once about the intraluminal aberrations, the spread to the surroundings and the abdominal status. The rapid, minimal invasive technology without sedation using multidetector CTs makes the method widely applicable. Aims: The authors search for the locus of CT colonography in the diagnostics of non-malignant diseases of the large intestine, in the screening of colorectal carcinoma and during tumor staging. Method: Data of 92 males (mean age: 61.2 ± 12.3 years) and 146 females (mean age 61.4 ± 12.5 years) were collected after CT colonography had been performed at Zala County Hospital between September 2002 and January 2007. Indications, protocols and results determining further business have been reviewed. Results: The reason of CT colonography was the failure of colonoscopy in 29% of the 238 patients. In 45/238 patients (19%) stricture of the colon, in 23/238 cases (10%) pain, lack of compliance and technical difficulties were the reasons of failure. In 60% of the remaining 23 persons organic intestinal diseases were diagnosed. In 151 cases (63%) the lack of informed consent for colonoscopy was the reason of radiological examinations, pathological abberations were found in every second patient. Aiming to learn the method, CT colonography was performed after total colonoscopy in 19/238 patients after informed consent. Conclusions: CT colonography is a useful tool in the algorithm of diagnostics of colorectal diseases in the case of lack of performing total colonoscopy.
