痰抗酸染色镜检目前是诊断肺结核的“金标准”,但临床上近2/3的患者痰抗酸染色“阴性”,使涂阴肺结核的诊断成为目前肺结核病诊断的难点。为此我们探讨了重复纤维支气管镜肺活检(TBLB)标本的病理检查对涂阴肺结核的诊断价值。1资料与方法1.1一般资料收集1992年1月～2005年1月我
Phlegm acid-fast staining is the gold standard for the diagnosis of pulmonary tuberculosis. However, nearly two-thirds of patients with sputum acid-fast staining are “negative” in sputum acid detection, which makes the diagnosis of smear-negative tuberculosis the difficult diagnosis of tuberculosis.
