内镜超声引导下细针穿刺抽吸术对胰腺占位病变的诊断价值及其影响因素

Diagnostic Value of Endoscopic Ultrasound-Guided Fine-Needle Aspiration for Pancreatic Space Occupying Lesions and Influencing Factors

目的探讨内镜超声引导下细针穿刺抽吸术对胰腺占位病变的诊断价值,分析相关影响因素。方法选取60例胰腺占位病变患者,均在内镜超声引导下行细针穿刺抽吸术,分析诊断结果以及诊断影响因素。结果内镜超声引导下细针穿刺抽吸术的总体诊断准确率为85.9%、敏感度为82.1%、特异度为97.1%、阳性预测值为98.2%、阴性预测值为65.2%,实性病灶的诊断准确率及敏感度显著高于囊性病灶(P <0.05)。胰腺病灶越大,诊断准确率越高(P <0.05)。结论内镜超声引导下细针穿刺抽吸术诊断胰腺占位病变的准确率高,胰腺病灶大小是影响诊断的重要因素。

Objective To explore the diagnostic value of endoscopic ultrasound-guided fine-needle aspiration for pancreatic space occupying lesions,and analyze the related influencing factors.Methods 60 patients with pancreatic space occupying lesions were selected.All cases received endoscopic ultrasound-guided fine-needle aspiration.The diagnosis results and the influencing factors of diagnosis were analyzed.Results The overall diagnostic accuracy,sensitivity,specificity,positive predictive value and negative predictive value of endoscopic ultrasound-guided fine-needle aspiration were 85.9%,82.1%,97.1%,98.2%and 65.2%respectively.The diagnostic accuracy and sensitivity for solid lesions were significantly higher than those for cystic lesions(P<0.05).The larger the pancreatic lesions,the higher the diagnostic accuracy(P<0.05).Conclusions Endoscopic ultrasound-guided fine-needle aspiration for the diagnosis of pancreatic space occupying lesions has high accuracy.The size of pancreatic lesions is an important factor affecting the diagnosis.
