目的探讨超声内镜引导下细针穿刺活检术(EUS-FNA)诊断和鉴别诊断胰腺肿瘤的价值。方法采用Olympus GF-UM30P穿刺超声内镜对62例胰腺肿瘤进行细针穿刺活检检查,而后将采集到的标本送病理检查。结果62例胰腺肿瘤中胰腺癌36例,胰管内肿瘤7例,假性囊肿8例,囊腺瘤5例,淋巴瘤3例,炎性假瘤2例,转移性淋巴瘤1例。经EUS-FNA 56例获得成功,其中穿刺成功的实性病灶均获得满意的细胞学和组织学标本,良恶性肿瘤穿刺成功率分别为100%、90%,诊断准确率为100%、87%。仅1例发生急性胰腺炎。结论EUS-FNA诊断胰腺肿瘤的准确率高,穿刺成功率高,且并发症极低,值得在临床推广。
Objective To investigate the value of endoscopic ultrasonography guided fine needle aspiration biopsy (EUS-FNA) in diagnosis and differential diagnosis of pancreatic tumors. Methods 62 cases of pancreatic tumors were examined by fine needle aspiration with Olympus GF-UM30P endoscopic ultrasonography, and the collected specimens were sent for pathological examination. Results There were 36 cases of pancreatic cancer, 7 cases of pancreatic ductal carcinoma, 8 cases of pseudocyst, 5 cases of cystadenoma, 3 cases of lymphoma, 2 cases of inflammatory pseudotumor and 1 case of metastatic lymphoma. 56 cases of EUS-FNA were successful. All the successful solid lesions were obtained satisfactory cytological and histological specimens. The success rates of benign and malignant tumor punctures were 100% and 90% respectively, the diagnostic accuracy was 100% and 87% . Only 1 patient developed acute pancreatitis. Conclusion The accuracy of EUS-FNA in the diagnosis of pancreatic tumors is high, the success rate of puncture is high, and the complication is extremely low. It is worth to be popularized clinically.
