Core Tip
Core tip: Computed tomographic colonography (CTC) is technically robust and the most practical method to evaluate the colon proximal to an occlusive cancer either before or after metallic stent placement. Contrast-enhanced CTC may serve as an effective stand-alone tool for post-cancer resection surveillance of both the colorectum and extracolonic organs. However, several issues discussed in this article should be addressed further and clarified.
