[Ultrasound, abdominal X-ray and dual-source CT in the diagnosis of colon tumor mechanical obstruction].

OBJECTIVE

To study the value of ultrasound, abdominal X-ray, and dual-source CT (DSCT) in the diagnosis of colon tumor obstruction.

METHODS

A retrospective analysis was conducted among 45 patients who were admitted to our department between October 2010 and August 2011 for abdominal pain. All the patients underwent ultrasound, abdominal X-ray and DSCT examinations and subsequent surgical interventions, which confirmed the diagnosis of colon tumor obstruction.

RESULTS

DSCT diagnosis was obviously more efficient than ultrasound and X-ray in detecting colon obstruction by neoplasms, and could better predict the position of the obstruction. Complete information of the vessels in the surgical field could be obtained by DSCT imaging three-dimensional reconstruction.

CONCLUSIONS

Compared with ultrasound and X-ray, DSCT is more effective in the diagnosis of colon tumor obstruction by acquiring more thorough information by imaging reconstruction and should be considered for a rapid and accurate diagnosis.
