BACKGROUND: The place of virtual colonoscopy (VC) in @entity1 with @entity30 ( @entity30 ) requiring endoscopic follow-up after surgery is unknown. The authors compared findings from VC versus conventional colonoscopy (CC) for assessing the postoperative recurrence of @entity30 . METHODS: Sixteen @entity1 with @entity254 for @entity30 were prospectively enrolled from January 2001 to January 2002. Recurrence was assessed by CC according to Rutgeerts et al. VC was performed with a computed tomography scanner, with images examined by three radiologists who were unaware of the endoscopic findings. RESULTS: CC showed perianastomotic recurrence in 15 of 16 @entity1 . @entity543 or @entity850 was detected by VC in 11 of these 15 @entity1 . There were 11 true positive, 1 true negative, 0 false-positive, and 4 false-negative findings (73% sensitivity, 100% specificity, 100% positive predictive value, 20% negative predictive value, 75% accuracy). Among the eight @entity1 showing a rigid @entity850 of the anastomosis not allowing passage of the colonoscope, VC detected narrowing or @entity850 in seven @entity1 . CONCLUSIONS: The current findings suggest that although the widespread use of VC in @entity30 is currently not indicated because of possible false-negative findings, this technique may represent an alternative to CC in noncompliant postsurgical @entity1 with a rigid @entity850 not allowing passage of the endoscope.
