改良穿刺针行肝脏病变穿刺230例应用研究

Appllied research of 230 cases in improving aspiration needle to perform puncture in liver pathological changes.

探讨改良穿刺针行肝脏病变穿刺细胞学检查效果。采用普通针头,在靠近针尖部位的侧壁制成2～3 个孔,针头上标记长度单位,病变小于3cm者,在B超引导下穿刺,病变大于3cm者,在B超定位后直接穿刺。病理诊断肝细胞癌212例、肝内转移癌8例、血管瘤5例、细菌性肝脓肿3例、阿米巴性肝脓肿2例。此方法避免了传统细针头穿刺抽吸时针管负压大、针孔容易阻塞、吸取物少、穿刺深度不易掌握等缺点,诊断准确率高。

To explore the effection of improving aspiration needle to perform puncture in liver pathologiehanges. Methods was to make 2 - 3 holes near the side of needle point. Marked the length, perform the leaded puncture under the B - uhrasonography when the pathological changes is under 3 cm, perform the direct puncture under the B - ultrasonography while the one is above 3 cm. To diagnose liver- cell carcinoma 212 cases, in - liver metastasis carcinoma 8 cases, haemangioma 5 cases, bacterial liver abscess 3 coses, amebic liver abscess 2 cases. It avoids the defects in high pressure in pump, easily obstruct, less imbibition, uneasily master in puncture length of fine - needle aspiration, it improves the veracity of diagnosis.
