内镜超声引导下细针穿刺活检对消化系统肿瘤的诊断价值

Diagnostic Value of Endoscopic Ultrasonography-guided Fine Needle Aspiration for Digestive System Neoplasms

影像学检查如CT、MRI、超声等对消化系统肿瘤的诊断具有重要意义,但部分消化系统肿瘤因其自身独特的临床特点,常规影像学检查不易早期发现并作出定性诊断。内镜超声引导下细针穿刺活检(EUS-FNA)不仅可发现早期病变,还能对病变作出准确的定性诊断,该技术的发展和完善极大地提高了消化系统肿瘤的诊断水平。本文就EUS-FNA对消化系统肿瘤的诊断价值作一综述。

Imaging examinations such as CT,MRI and ultrasonography are of great importance for the diagnosis of digestive system neoplasms.However,some digestive system neoplasms are difficult to be detected at early stage and make qualitative diagnosis by conventional imaging techniques because of their unique clinical characteristics.Compared with conventional imaging techniques,endoscopic ultrasonography-guided fine needle aspiration(EUS-FNA)can not only detect the early lesions,but also make accurate qualitative diagnosis.The development and improvement of EUS-FNA greatly improve the diagnostic level of digestive system neoplasms.In this paper,the diagnostic value of EUS-FNA in digestive system neoplasms was reviewed.
