THE CLINICAL ANALYSIS OF RADIOGRAPHY, ULTRASONOGRAPHY(US) AND CT FOR INTESTINAL OBSTRUCTION

Objective To investigate the diagnostic value of radiography,ultrasonography(US) and CT for intestinal obstruction.Methods 367 patients with intestinal obstruction from November 2002 to June 2005 who underwent the operation were reviewed retrospectively.The diagnostic value of clinical radiography,US and CT for intestinal obstruction was comparatively studied.Results The correct proportions of diagnosis of intestinal obstruction for radiography,US and CT were 91.94%,81.56% and 95.88%;obstructive locations were 80.30%,37.99% and 85.57%;the obstructive causes were 42.69%,31.85% and 81.44%;the correct proportions of diagnosis of strangulated intestinal obstruction were 14.63%,63.18% and 82.14%.Conclusions There was no evident difference in diagnosis of obstruction and obstructive location between radiography and CT,but CT was found to be more accurate at determining the causes of obstruction and detecting strangulation.US is helpful in the diagnosis of strangulated intestinal obstruction.
