Usefulness of CT colonography in patients with incomplete colonoscopy.

Use of Modified Multidetector CT Colonography for the Evaluation of Acute and Subacute Colon Obstruction Caused by Colorectal Cancer

“…Several other investigations of CT colonography performed with single-slice CT scanners in patients with obstructive colorectal cancer have reported excellent results for imaging of the colon proximal to the obstruction, despite difficulties in colon cleansing. 4,5,20,21 The use of both the prone and the supine position was valuable in our study because of the redistribution of residual fluid and stool, and because of a better distention of some segments of the colon at different positions (Fig. 3).…”

CT colonography after incomplete colonoscopy in subjects with positive faecal occult blood test

“…Previous studies on CTC after incomplete colonoscopy have been conducted [6][7][8][9][10] . These studies were inhomogeneous regarding the patients' selection, because they included asymptomatic as well as symptomatic subjects.…”

“…In order to complete evaluation of the colon, radiological examinations can be performed such as double contrast barium enema (DCBE) [5] and computed tomography colonography (CTC). In particular, several studies have shown that CTC is a valuable tool to evaluate the proximal colon after incomplete colonoscopy [6][7][8][9][10] , and the American Gastroenterologists Association (AGA) recognized that CTC is indicated for adults with failed colonoscopy [11] . We report the results of CTC systematically performed in subjects with positive FOBT and incomplete colonoscopy in the context of a population-based screening programme for CRC with FOBT.…”

Virtual colonoscopy: Utility, impact and overview

“…Patients with failed or incomplete colonoscopy (5%-10%), those who are reluctant to undergo OC or those who may be at an increased risk with OC can be evaluated by CTC (Figures 1 and 2) [21,22] . CTC has been used in the evaluation of patients presenting with obstructing colonic neoplasms and rarely in inflammatory bowel disease [23][24][25] .…”
