内镜超声引导下细针穿刺活检术对胰腺占位病变的诊断价值

目的 探讨内镜超声引导下细针穿刺活检术（EUS-FNA）对胰腺占位病变的诊断价值.方法 收集2009-05～2011-06因胰腺占位病变行EUS-FNA病人16例,回顾性总结分析EUS-FNA病理诊断的阳性率及穿刺活检的安全性.结果 EUS-FNA病理结果中,腺癌8例,假性乳头瘤状1例,胰腺导管内乳头状黏液瘤（IPMT）1例,炎性6例,阳性检出率为62.5%.其中4例行手术治疗,手术结果与EUS-FNA结果符合3例,符合率为75%.结论 EUS-FNA对胰腺占位的定性诊断具有较高的准确性及安全性.

Evaluation of EUS guided fine-needle aspiration in focal pancreatic lesion

Objective To evaluate the role of endoscopic ultrasound-guided fine-needle aspiration （EUS- FNA） for diagnosis of focal pancreatic lesion. Methods 16 patients with focal pancreatic lesions who underwent EUS-FNA from May 2009 to June 2011 were retrospectively analyzed. Surgical-pathological result was used as the reference standard for diagnosis. Results Sixteen patients were diagnosed by EUS-FNA as adenccaroinomas （ n = 8 ）, pseudo-papillomas （ n = 1 ）, intraductal papillary mucinous tumor （ n = 1 ）,inflammation （n = 6）. The diagnostic sensitivity and accuracy of focal pancreatic lesion by EUS-FNA were 62. 5% and 75% respectively. Conclusion EUSFNA was an accurate and safe modality in diagnosis of fccal pancreatic lesion.
