超声引导经皮细针穿刺活检在胰腺占位性病变诊断中的作用

目的 探讨超声引导经皮细针穿刺组织学活检在胰腺占位性病变诊断中的价值。方法 96例胰腺占位病变患者，用BARD自动活检枪和20G活检切割针行超声引导下经皮穿刺活检。结果 本组穿刺活检成功率100％，取材满意率83．3％（80／96）。90例获得明确病理诊断，包括胰腺癌61例，胰腺囊腺癌15例，胰腺炎性病变13例，无功能性胰岛细胞瘤1例，6例因组织标本量少未提示病理诊断，本组诊断准确性93．7％，无严重并发症发生。结论 超声引导经皮细针穿刺胰腺病变组织学活检是一种简便、安全、有效、诊断准确性高的方法，可使多数患者获得明确的病理诊断，为临床治疗提供依据。

Diagnostic Value of Ultrasonography Guided Fine-needle Percutaneous Biopsy in Pancreatic Masses

Objective To evaluate the role and safety of ultrasonography guided fine-needle percutaneous biopsy in pancreatic masses.Methods Ninety-six patients with various pancreatic masses underwent ultrasonography guided percutaneous biopsy using Bard auto-biopsy gun and 20-gauge biopsy needle.Results The successful rate of our percutaneous biopsy was 100%(96/96)and the satisfaction rate of the tissue sample was 83.3%(80/96).Ninety cases got specific pathology diagnosis,including 61 cases with pancreatic adenocarcinoma,15 with pancreatic cystadenocarcinoma,13 with inflammatory pancreatic lesions and 1 with nonfunctional islet cell tumor.Six cases got no get pathologic diagnosis for little amount of tissue sample.The diagnostic accuracy was 93.8% and no serious complications occurred.Conclusions Fine-needle percutaneous biopsy with ultrasonographic guidance can be used conveniently,safely and efficiently for diagnosing pancreatic masses.It makes more patients get accurate diagnosis and offers basis for clinical therapy.
