提高纤支镜活检病理诊断的阳性率,一是应将纤支镜下所见,包括粘膜皱襞图象,粘膜面,支气管腔,分泌物等记载好,这实际上是病理的肉眼形态部分,对病理诊断有重要参考价值;二是选择好活检的取材部位。纤维支气管镜下所取的活检组织是微小的,但必须包括血块和坏死组织。切片时最好作连续切片10～20个。过去我们仅切5个组织片,往往在可疑病例需重新切片时,由于修整蜡块而损失组织,所剩无几,得不到结果。切片时应留数个白片以备作特殊染 To increase the positive rate of pathological diagnosis of bronchoscopic biopsy, one should record the findings seen under the bronchoscope, including mucosal folds, mucosal surfaces, bronchial cavities, and secretions. This is actually the pathological appearance of the naked eye. It has important reference value for pathological diagnosis; second, it selects the location of the biopsy. The biopsy taken under fiberoptic bronchoscopy is small but must include blood clots and necrotic tissue. When slicing, it is best to make 10 to 20 consecutive slices. In the past, we only cut 5 pieces of tissue. Often when suspicious cases need to be re-sliced, the tissue will be lost due to trimming the wax block. Several white pieces should be reserved for special dyeing
