经皮经肝淋巴造影术在胰头癌区域淋巴结转移中的诊断价值

Diagnostic value of PTL on regional lymph nodes metastasis in patients with pancrea head cancer

目的探讨经皮经肝淋巴造影术(PTL)在胰头癌区域淋巴结转移中的诊断价值。方法选择13例可切除的胰头癌患者,通过术前CT和PTL判断是否有区域淋巴结转移,并与术后病理结果比较。结果本组中12例行根治性胰十二肠切除术,1例行姑息性手术;术前PTL、CT诊断胰头癌区域淋巴结转移的敏感性、特异性及准确性分别是76.5%、83.3%、78.2%;64.7%、66.7%、65.2%;经比较,三者差异具有统计学意义(P<0.05)。结论 PTL在胰头癌区域淋巴结转移的诊断中有较高的临床应用价值。

Objective To explore the diagnostic value of percutaneous transhepatic lymphography on regional lymph nodes metastasis in patients with pancrea head cancer.Methods 13 patients with resectable pancrea head cancer were chosen from January 2008 to June 2010,and the results of CT examination and PTL performed preoperatively on them were compared with the pathologic identification.Results 12 cases underwent radical pancreatoduodenectomy and 1 palliative operation.The sensitivity,specifity and acuracy in the diagnosis of regional lymph node metastasis were 77.8%,75% and 76.9% respectively in PTL,55.6%,50% and 53.8% in CT.There were significant diference（P0.05） between the two groups of CT and PTL.Conclusion PTL is an usuful method in the diagnosis of regional lymph node metastasis in patients with pancrea head cancer.
