[Clinical Value of Multi-slice Spiral Enhanced CT in Diagnosing Mild Digestive Tract Hemorrhage]

Objective To investigate the clinical value of multi-slice spiral CT(MSCT) in the diagnosis of mild digestive tract hemorrhage. Methods Thirty-five patients with mild gastrointestinal hemorrhage were examined by enhanced MSCT.CT signs were observed and compared with pathologic examination findings.Results Diseases in these 35 patients included gastric and duodenal ulcer and inflammation(n=4,11.4%),esophagogastric variceal rupture(n=7,20.0%),gastric carcinoma(n=3,8.6%),gastric stromal tumor(n=3,8.6%),gastric polyp(n=1,2.9%),colonic malignancy(n=5,14.2%),small intestinal stromal tumor(n=6,17.1%),rectal cancer(n=2,5.7%),intestinal Crohn disease(n=3,8.6%),and jejunum diverticulum combined with hemorrhage(n=1,2.9%).All of them were diagnosed by endoscopy of the digestive tract and confirmed by operation and pathology.The accuracy rate of CT was 100%.The coincidence rate of CT diagnosis was 97.1%.Conclusion MSCT is a promising technique in the localization,qualitative diagnosis,and clinical treatment of mild gastrointestinal hemorrhage.
