目的评估胆胰管内超声内镜检查(IDUS)在胰腺疾病中的诊断价值。方法回顾分析2005年2月至2010年2月间行IDUS的63例胰腺疾病患者的影像学资料,IDUS均在经内镜逆行胰胆管造影(ERCP)时用经导丝的UMG20-29R腔内超声探头扫查胰腺。比较IDUS与CT、MRI、超声内镜(EUS)及腹部B超等5种方法在诊断胰腺疾病中的区别,以进一步评估IDUS在胰腺疾病的临床诊断中的应用价值。结果 IDUS对慢性胰腺炎(23例)、胰腺癌(10例)、导管内乳头状黏液瘤(IPMT,25例)、胰腺囊腺瘤(4例)的诊断准确率和Kappa检测值分别为93.7%(59/63),0.854;100.0%(63/63),1.00;90.5%(57/63),0.898以及96.8%(61/63),0.848。IDUS诊断准确率和Kappa检测值均优于其他4种方法 ,并且对1例胰腺囊腺癌也做出正确的术前诊断。结论 IDUS对胰腺疾病的诊断有较高的应用价值。
Objective To evaluate the diagnostic value of intraductal ultrasonography (IDUS) in pancreatic diseases. Methods The imaging data of 63 patients with pancreatic diseases who underwent IDUS between February 2005 and February 2010 were retrospectively analyzed. All the IDUS patients underwent endoscopic retrograde cholangiopancreatography (ERCP) with the guidewire of UMG20-29R Ultrasound probe scan the pancreas. To compare the difference between IDUS and CT, MRI, EUS and abdominal B-ultrasonography in the diagnosis of pancreatic diseases in order to further evaluate the value of IDUS in the clinical diagnosis of pancreatic diseases. Results The diagnostic accuracy and Kappa value of IDUS for chronic pancreatitis (23 cases), pancreatic cancer (10 cases), intraductal papillary myxoma (IPMT, 25 cases) and pancreatic cystadenoma (4 cases) were 93.7 % (59/63), 0.854; 100.0% (63/63), 1.00; 90.5% (57/63), 0.898 and 96.8% (61/63), 0.848. IDUS diagnostic accuracy and Kappa detection value are better than the other four methods, and 1 cases of pancreatic cystadenocarcinoma also make the correct preoperative diagnosis. Conclusion IDUS has a high value in the diagnosis of pancreatic diseases.
