The purpose of this study was to compare dual-phase helical CT and endosonography for the diagnosis and staging of pancreatic tumors.
Thirty patients with suspected pancreatic tumors underwent endosonography and dual-phase helical CT. A pathologic diagnosis was obtained in all cases with surgery (n = 23) or biopsy (n = 7), resulting in 27 neoplasms. Dual-phase helical CT and endosonographic findings were correlated with surgical and pathologic findings to determine diagnosis and resectability of pancreatic tumors.
Overall diagnostic sensitivity was 92% for dual-phase helical CT and 100% for endosonography (p = .45). Overall accuracy for staging of pancreatic tumors was 93% for both dual-phase helical CT and endosonography. Overall accuracy for predicting resectability was 90% for both dual-phase helical CT and endosonography. Accuracy of predicting unresectability was 100% for dual-phase helical CT and 86% for endosonography (p > .80). Differences were not considered statistically significant.
Dual-phase helical CT and endoscopic sonography do not differ significantly for diagnosis and assessment of resectability of pancreatic tumors.
本研究旨在比较双期螺旋CT和内镜超声对胰腺肿瘤的诊断及分期。
30例疑似胰腺肿瘤患者接受了内镜超声和双期螺旋CT检查。所有病例均通过手术（n = 23）或活检（n = 7）获得病理诊断，共确诊27例肿瘤。将双期螺旋CT和内镜超声检查结果与手术及病理结果进行对比，以确定胰腺肿瘤的诊断及可切除性。
双期螺旋CT的总体诊断敏感性为92%，内镜超声为100%（p = 0.45）。双期螺旋CT和内镜超声对胰腺肿瘤分期的总体准确率均为93%。双期螺旋CT和内镜超声对预测可切除性的总体准确率均为90%。双期螺旋CT对预测不可切除性的准确率为100%，内镜超声为86%（p > 0.80）。差异无统计学意义。
双期螺旋CT和内镜超声在胰腺肿瘤的诊断及可切除性评估方面无显著差异。
