CT透视引导下细针抽吸活检并T.B.O快速染色诊断胸部疾病的价值

目的：研究CT透视引导下细针抽吸活检结合床边T．B．O快速染色对胸部疑难疾病的诊断价值。方法：回顾分析胸部疑难疾病48例，所有病例均运用CT透视引导细针抽吸，常规进行床边T．B．O快速染色判断，并与涂片及或细胞团切片H．E染色诊断(必要时免疫细胞化学辅助诊断)、最后诊断对照分析。结果：CT导引下穿刺成功率100％。均并行床边T．B．O快速染色后标本判断。本组48例中，恶性病变42例，良性病变6例，床边T．B．O染色判断良、恶性准确率98％(47/48)，总的诊断准确率92％(44/48)。穿刺次数1—2次，无假阳性、无严重并发症发生。结论：CT透视引导下细针抽吸活检准确、安全，床边T．B．O快速染色简单易行，二者结合诊断准确率高，对胸部疑难疾病尤其是胸部小病灶或靠近大血管病灶的诊断具有重大价值。

Diagnostic values of CT fluoroscopy guided fine needle aspiration biopsy combining with T.B.O quick staining bedside in the pectoral interrogative illness

Objective:To evaluate diagnostic values of CT fluoroscopy (CTF) guided fine needle aspiration biopsy (FNAB) combining with toluidine blue O(T.B.O)quick staining bedside in the pectoral interrogative illness.Methods:48 patients with pectoral interrogative illness during May 2002 and Dec 2003 in our hospital were reviewed. All patients underwent CTF guided FNAB and quickly judged by T.B.O staining bedside. Compared T.B.O and hematoxylin and eosin(H.E) staining (sometimes need aid of immunocytochemistry (ICC) and last diagnosis.Results:48 cases of CTF guided FNAB were succeeded. Using T.B.O quick staining bedside can quickly estimate the sample whether it is enough or representative and can judge benign or malignant cells and its style. The veracity of T.B.O quick staining bedside is 98%(47/48)and the total veracity of diagnosis is 92%(44/48). The frequency of puncture is once or twice. No false-positive and serious complications.Conclusion:The security and veracity of CTF guided FNAB in the pectoral interrogative illness, specially for some small nodules or which close great blood vessel is reliable. T.B.O quick staining is easy. It has a great diagnostic values of CTF guided FNAB with T.B.O quick staining bedside in the pectoral interrogative illness.
