In this study, physicians from Rome, Italy, compared virtual colonoscopy with conventional colonoscopy for assessing postoperative recurrence in Crohn's disease.
They examined 16 patients with ileocolonic anastomosis for Crohn's disease between 2001 and 2002.
|There were 11 positives, 1 negative, no false-positives, and 4 false-negatives.|

The team was assessed recurrence using conventional colonoscopy.
They then performed virtual colonoscopy using a computed tomography scanner. Images were examined by 3 radiologists who were blinded to the results of the endoscopies.
The physicians identified perianastomotic recurrence in 15 of 16 patients using conventional colonoscopy.
However, perianastomotic narrowing or stenosis was detected by virtual colonoscopy in only 11 of these patients.
The team found that there were 11 positives, 1 negative, no false-positives, and 4 false-negatives in this study.
They found that, in the 8 patients with a rigid stenosis of the anastomosis that did not allow passage of the colonoscope, the virtual colonoscopy detected narrowing or stenosis in 7 patients.
Dr Livia Biancone's team concluded, "Widespread use of virtual colonoscopy in Crohn's disease is currently not indicated because of possible false-negative findings".
However, "This technique may represent an alternative to conventional colonoscopy in noncompliant postsurgical patients with a rigid stenosis not allowing passage of the endoscope".
