作者报告1978～1984年间的240例怀疑胰腺和胆系肿瘤病人的细针穿刺活检。其中1978～1982年间仅用超声引导穿刺,其技术灵敏性,胰腺肿瘤为66.7％,胆系肿瘤为40％。1983～1984年则采用超声与透视结合引导穿刺并常规进行胰,胆管造影同时使用强镇静剂,以利于穿刺位置更加准确。此间技术灵敏性提高,胰腺肿瘤为77.5％,胆系肿瘤为60％。作者认为,细针穿刺活检是确诊恶性病变的一种简易而又准确的方法,但此技术用于胰、胆系肿瘤的成功率低于其它肿瘤。原因可能有以下几
The authors report fine needle aspiration biopsy in 240 patients with suspected pancreatic and biliary tumors from 1978 to 1984. Among them, only ultrasound-guided puncture was performed between 1978 and 1982, and its technical sensitivity was 66.7% for pancreatic tumors and 40% for biliary tumors. From 1983 to 1984, ultrasound and fluoroscopy were used to guide puncture and conventional pancreatic and cholangiopancreatography simultaneously used strong sedatives to facilitate more accurate puncture site. During this period, the sensitivity of the technique was improved, with 77.5% of pancreatic tumors and 60% of biliary tumors. The author believes that fine needle aspiration biopsy is a simple and accurate method for the diagnosis of malignant lesions, but the success rate of this technique for pancreatic and biliary tumors is lower than other tumors. The reason may be the following
