عنوان انگلیسی The Diagnostic Value of Mesenteric Vessel Abnormalities on Ultrasound for Malrotation
چکیده انگلیسی مقاله Background: Malrotation is an emergency, mainly in pediatric cases, and needs a timely and prompt diagnosis. Upper gastrointestinal (GI) contrast study used to be an acceptable modality in the diagnosis of malrotation; however, it has many disadvantages. In this regard, sonography has tried to take the place of upper GI studies. The aim of our study is to assess sonography and upper GI series as diagnostic methods for malrotation. Methods: In a cross-sectional study, 154 pediatric cases suspected of malrotation were enrolled. The patients underwent upper GI series and sonography. In the case of sonography, two different findings, including inversion of the superior mesenteric vein (SMV) and superior mesenteric artery (SMA) and deviation (abnormal pathway) of the mesenteric artery were assessed. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of different sonography findings and upper GI study were calculated. Result: Different sonography findings showed various diagnostic values. Inversion of SMV/SMA had a sensitivity of 58.87%, specificity of 36.17%, PPV of 67.74%, and NPV of 27.86%. Furthermore, the sensitivity, specificity, PPV, and NPV of deviation (abnormal pathway) of mesenteric vessels were 89.87%, 17.02%, 64.54%, and 50%, respectively. Taking into consideration the two findings together, sonography showed a sensitivity of 73.83% and PPV of 67.74%. Moreover, the sensitivity, specificity, PPV, and NPV of upper GI studies were 82.5%, 100%, 100%, and 50%, respectively. Conclusion: Mesenteric vessel abnormalities may be valuable in detecting malrotation, but still upper GI contrast study is better. Development of other sonographic markers of malrotation, especially for different ages, is necessary.
