AIM: @entity1 referred under the Department of Health 2-week wait initiative with symptoms of @entity14 frequently undergo whole-colon examination. We investigated the use of computed tomography (CT) colonography as an alternative to colonoscopy in this scenario. MATERIALS AND METHODS: Fifty-four consecutive @entity1 , referred via the 2-week wait initiative and scheduled for colonoscopy, consented to undergo multidetector CT colonography immediately before endoscopy. The site and morphology of any @entity1127 or @entity5 detected by CT was noted and comparison made with subsequent colonoscopy. RESULTS: Colonoscopy detected @entity1127 or @entity5 in 29 @entity1 (53.7%). CT colonography prospectively detected 18 of 41 (44%) @entity1127 of 1-5 mm, three of four (75%) @entity1127 of 6-9 mm, four of four (100%) @entity1127 10 mm or larger, and five of six (83%) @entity5 . The missed @entity5 occurred early in the series and was a perceptive error. The overall sensitivity, specificity, positive predictive value and negative predictive value of CT colonography for @entity5 and @entity1127 10 mm or greater on a per @entity1 basis were 90, 100, 100 and 98%, respectively. CT detected one @entity703 and one @entity694 , initially missed due to incomplete colonoscopy. CONCLUSION: CT colonography is a robust technique for investigation of symptomatic @entity1 . The learning curve must be overcome for optimal performance.
