We feel that the overtube makes the ileocecal valve less pliable as the ascending colon is straightened out, which together with the inherent flexibility of the enteroscope as compared to a colonoscope makes it more difficult to intubate the terminal ileum using the usual antegrade approach, thus requiring retroflexion for small bowel intubation.
The following potential pitfalls in the interpretation of CT colonography have to be considered: Fluid-filled segments and collapsed segments, retained stool, complex and bulbous folds, lipomas, foreign bodies, diverticulosis, the ileocecal valve, and extrinsic compression defects.
