内镜超声引导下细针穿刺活检术对腹腔占位病灶的诊断价值

目的探讨内镜超声引导下细针穿刺活检术(EUS-FNA)对腹腔占位病灶的诊断价值和安全性。方法收集2009-05～2011-06因腹腔占位行EUS-FNA的患者19例,回顾性分析EUS-FNS病理的阳性率及EUS-FNA与手术后病理的符合率。结果 19例患者穿刺病理结果,腺癌11例,假性乳头状瘤1例,胰腺导管内乳头状黏液瘤(IPMT)1例,炎性改变6例,穿刺检查阳性率为68.4%。其中7例行手术治疗,术后病理与穿刺标本病理或细胞学结果符合6例,符合率为86.0%。本组19例患者EUS-FNA术后无出血、穿孔、感染及急性胰腺炎等并发症。结论 EUS-FNA是一项准确而安全有效的技术,对腹腔占位病灶尤其是胰腺肿瘤的定性诊断及进一步治疗方案的确定具有重要的临床价值。

Evaluation of EUS guided fine needle aspiration in focal celiac lesion

Objective To evaluate the role of endoscopic ultrasound-guided fine needle aspiration(EUSFNA) for diagnosis and safety of focal celiac lesion.Methods Nineteen patients with focal celiac 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 Nineteen patients were diagnosed by EUS-FNA as adenocarcinomas (n =11),pseudo- papillomas(n = 1),intraductal papillary mucinous tumor(n = 1),inflammation(n = 6 ).The diagnostic sensitivity and accuracy of focal celiac lesion by EUS-FNA were 68.4%and 86.0%respectively.Conclusion EUS-FNA was an accurate and safe modality in diagnosis of focal celiac lesion.
