RESUMEN
OBJECTIVE: Our aim was to develop an insufflation system for CT colonography enabling even and quick air inflation as well as pressure control and optional emergency decompression. PATIENTS AND METHODS: A modified air insufflation system for CT colonography, consisting of an electric air pump, manometer, safety valve, and a balloon tip is presented. Thirty one patients underwent CT colonography from August to December, 2004. RESULTS: Optimal distension was achieved in 30 patients; the distension was incomplete (partial) only in one case. The insufflation was performed within 60 seconds in 28 of the cases, in 2 patients--within 180 seconds and in one patient--after 180 seconds. CONCLUSIONS: The presented insufflation system allows optimization of CT colonography technique, reduces the risk of adverse events during examination and improves the precision of the method.
