Analysis on application value of 16 slice spiral CT in diagnosis of acute intestinal obstruction

Objective To analyze the application value of 16 slice spiral CT in diagnosis of acute intestinal obstruction.Methods The clinical data and X-ray and 16 slice spiral CT examination data in 65 cases with confirmed acute intestinal obstruction in our hospital from Jan.2009 to Dec.2013 were retrospective analyzed.The sensitivity,specificity and accuracy of 16 slice spiral CT and X-ray examinations for diagnosing acute intestinal obstruction were compared and the accuracy of 16 slice spiral CT for judging the site and pathogenesis of acute intestinal obstruction was analyzed.Results The sensitivity,specificity and accuracy of 16 slice spiral CT examination for diagnosing acute intestinal obstruction were 96.92%,88.89% and 95.95% respectively,which were significantly higher than81.54%,66.67% and 79.73% of X-ray plain film examination,the difference was statistically significant(χ2=10.31,13.27,11.44,P0.05);the coincidence rate of intestinal obstruction localization diagnosis in 16 slice spiral CT was 92.31%and its etiological diagnosis coincidence rate was 90.77%.Conclusion 16 slice spiral CT could have a high application value in diagnosis of acute intestinal obstruction,and judging the obstruction location and pathogenesis of acute intestinal obstruction.
