Role of Multi-Detector CT (MDCT) in Diagnosis of Intestinal Obstruction

Abstract

Background CT is appropriate imaging modality for evaluation of patients with suspected intestinal obstruction in whom clinical examination and radiography do not yield a definitive diagnosis. CT is sensitive for detection of high-grade obstruction and has the additional benefit of defining the cause and level of obstruction. Aim of the Work The aim of this study is to evaluate the role of MDCT in the diagnosing of intestinal obstruction, detection of its causes and possible complications, and to correlate the association between imaging features and operative finding. Patients and Methods A cross sectional study was conducted including 31 patients between 7 months and 75 years with clinically suspected intestinal obstruction. Patients underwent multi-detector CT. Image interpretations performed by Independent radiologists were compared with the final diagnosis that was based on clinical and lab information as well as surgical findings in operated cases. Results Adhesive intestinal obstruction was the main cause of small bowel obstruction while adenocarcinoma was the main cause of large bowel obstruction in our study. The most common site diagnosed on CT was jejunum (87.1%). Highly significant correlation was found between CT and operative findings in the diagnosis of the site and cause of obstruction with P value of < 0.001. Conclusion MDCT is highly accurate and specific in the diagnosis of intestinal obstruction. It can demonstrate the exact site of obstruction, as a result it is useful for developing an appropriate treatment plan and managing the patient.
