摘要
目的分析消化道碘剂造影联合CT后重建对于肠梗阻的诊断价值。方法选取100例疑为肠梗阻患者,分别进行消化道碘剂造影以及CT后重建检查,以综合临床症状、体征、实验室与影像学检查的最终诊断为标准,比较单一消化道碘剂造影检查、单一CT后重建检查与消化道碘剂造影联合CT后重建的诊断效能。结果本组100例患者最终诊断肠梗阻58例。消化道碘剂造影诊断肠梗阻55例,漏诊10例,误诊7例;CT后重建诊断肠梗阻56例,漏诊8例,误诊6例;消化道碘剂造影联合CT后重建诊断肠梗阻57例,漏诊2例,误诊1例。消化道碘剂造影联合CT后重建的敏感度、特异度、准确度、阳性预测值、阴性预测值分别为96.6%(56/58)、97.6%(41/42)、97.0%(97/100)、98.2%(56/57)、95.3%(41/43),均高于单一消化道碘剂造影的82.8%(48/58)、83.3%(35/42)、83.0%(83/100)、87.3%(48/55)、77.8%(35/45)及单一CT后重建的86.2%(50/58)、85.7%(36/42)、86.0%(86/100)、89.3%(50/56)、81.8%(36/44),差异有意义(P<0.05)。结论消化道碘剂造影联合CT后重建诊断肠梗阻的价值高于单一消化道碘剂造影检查与单一CT后重建检查,能够减少漏诊误诊情况,可推广使用。
Objective To analyze the diagnostic value of gastrointestinal iodine contrast combined with CT reconstruction in intestinal obstruction.Methods A total of 100 patients suspected of intestinal obstruction were selected.All patients underwent gastrointestinal iodine contrast and CT reconstruction,respectively.With the final diagnosis of comprehensive clinical symptoms,signs,laboratory and imaging examinations as the standard,the diagnostic efficiency of iodine contrast and CT reconstruction alone and in combination was compared.Results 58 of the 100 patients were diagnosed with intestinal obstruction.Gastrointestinal iodine contrast diagnosed 55 cases of intestinal obstruction,with 10 missed cases and 7 misdiagnosed cases;CT reconstruction diagnosed 56 cases of intestinal obstruction,with 8 missed cases and 6 misdiagnosed cases;gastrointestinal iodine contrast combined with CT reconstruction diagnosed 57 cases of intestinal obstruction,with 2 missed cases and 1 misdiagnosed case.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of gastrointestinal iodine contrast combined with CT reconstruction were 96.6%(56/58),97.6%(41/42),97.0%(97/100),98.2%(56/57)and 95.3%(41/43),which were higher than those of single gastrointestinal iodine contrast[82.8%(48/58),83.3%(35/42),83.0%(83/100),87.3%(48/55)and 77.8%(35/45)]and single CT reconstruction[86.2%(50/58),85.7%(36/42),86.0%(86/100),89.3%(50/56)and 81.8%(36/44)].The difference was significant(P<0.05).Conclusion The diagnostic value of gastrointestinal iodine contrast combined with CT reconstruction is higher than that of single gastrointestinal iodine contrast or CT reconstruction,which can reduce the missed diagnosis and misdiagnosis,and can be widely used.
