Abstract
Purpose: To evaluate role of multidetector CT Enterog-raphy (CTE) in diagnosis of small intestinal tumors.
Material and Methods: Sixty six patients (40-76 years) presented with clinical suspicion of small intestinal tumors. They underwent CTE with a 64 multidetector CT before operation. Two independent gastrointestinal radiologists analysed CTE images. Post operative histopathological exam-ination was considered the reference standard. Sensitivity, specificity, accuracy, positive and negative predictive value were calculated.
Results: Positive radiological findings suggestive of small intestinal tumors were obtained in 34 cases and negative in 32 cases. Pathology confirmed diagnosis in 29 cases: Gas-trointestinal stromal tumor (n=13), Non Hodgkin lymphoma (n= 11), Carcinoid tumor (n=2), one case of adenocarcinoma of the deodenum, one case of liomyosarcoma of the ileum and one case of metastatic deposits from colonic adenocarci-noma. Overall sensitivity, specificity and accuracy of CTE in detection of small intestinal tumors were 82.8%, 83.8% and 83.3% respectively with positive predictive value of 85.2% and negative predictive value of 81.2%.
Conclusion: Multidetector CTE is a promising valuable tool that helps in precise localization, characterization and staging of small bowel tumor with high diagnostic accuracy.
