Role of CT virtual colonoscopy versus conventional colonoscopy in the evaluation of colonic polyps

Virtual colonoscopy is one of the recent advances in the field of CT post processing technique. It represents a type of 3D reconstruction technique which is capable of elaborating endoscopic endoluminal display of the colon without the use of real endoscope and hence it was named virtual colonoscopy. The aim of work is to evaluate the role of virtual colonoscopy in colonic polyps.Subject and methodsOur study included 35 patients; 25 of them had positive colonic polyps. They ranged in age from 22 to 79 years. All patients were subjected to virtual colonoscopy examination and results were compared to conventional colonoscopy and documented by histopathology in all cases.ResultsThe results in our study showed that conventional colonoscopy is a little bit ahead in front of virtual colonoscopy, yet the results are more or less comparable to each other.
