Dr. Madhusudhan S | Dr. Anil Kumar K N | Dr. K. Nischal


Abstract: Background: Colorectal cancer (CRC) is amajor health issue affecting population worldwide in recent years. Conventional colonoscopy is the gold standard investigation used for screening and diagnosis of CRC but associated with its own disadvantages in the form of pain, discomfort, abdominal distension and rarely perforation. CECT abdomen is a radiological technique to evaluate the colon without morbidities of conventional colonoscopy. Aims and Objectives: To evaluate the sensitivity and specificity of contrast computed tomography in comparison with conventional colonoscopy. Methodology: Study was conducted from January 2019 to December 2019 on 38 patients. This is a prospective double - blind study. Patients underwent conventional colonoscopy followed by CECT abdomen after informed consent. The conventional colonoscopy findings were regarded as gold standard and were compared with contrast computed tomography in relation to location and type of the lesion. Histopathological findings were noted in patients in whom biopsy was performed. Results: Intraluminal findings of both the investigations were comparable except few incomplete evaluations in conventional colonoscopy secondary to obstructive growth or poor patient compliance. CECT had additional advantages like fat stranding and enlarged lymph nodes but with a drawback of no tissue diagnosis. CECT abdomen and conventional colonoscopy was successful in all patients. Sensitivity of the CECT abdomen was 100% with positive predictive value of 100% in comparison to conventional colonoscopy. Specificity could not be assessed as only positive cases on conventional colonoscopy were taken. Conclusion: Accuracy of CECT abdomen is equivalent to conventional colonoscopy and can be used for evaluating as primary tool in assessing colorectal pathologies.
