目的：评估一种肺活检技术，在该技术中，一个可拆卸的、18号、同轴的引导器围绕着一个中央缺口针头作为切割针。材料与方法：对89例连续患者（41例女性，48例男性，年龄21-86岁）的记录进行了研究，这些患者对91个需要通过正常肺组织的肺病变（平均病变大小33.6 mm，范围9-80 mm）进行了同轴经皮核心活检。使用可拆卸的18径同轴自动切割针。结果：平均针次2.5次（范围1 ~ 4）。所有活检均有足够的组织用于组织病理学（n = 91）和必要时细菌学（n = 12）评估（平均核心长度5毫米；范围1-15毫米）。89个病灶有明确诊断。75个病灶被证实为恶性；70例（93%）可通过同轴穿刺活检准确诊断。14个病变被证明是良性的；10例（71%）通过活检确诊。在91例活检中，总体诊断准确率为88%（80 / 91个病变）。31例（34%）发生气胸，其中3例（3%）需要放置胸管。9例（10%）活检后出现咯血并自行消退。结论：该技术提供了一个核心活检标本，而不需要现场细胞病理学家在过程中。它具有较高的诊断准确性和可接受的并发症发生率。
PURPOSE: To evaluate a lung biopsy technique in which a detachable, 18-gauge, coaxial guide around a central notched stylet is used as a cutting needle.MATERIALS AND METHODS: The records of 89 consecutive patients (41 women, 48 men; aged 21-86 years) who underwent coaxial percutaneous core biopsy of 91 lung lesions that required needle passage through normal lung tissue (mean lesion size, 33.6 mm; range, 9-80 mm) were studied. Detachable, 18-guage, coaxial automated cutting needles were used.RESULTS: The mean number of needle passes was 2.5 (range, 1-4). All biopsies yielded sufficient tissue for histopathologic (n = 91) and, if necessary, bacteriologic (n = 12) evaluation (mean core length, 5 mm; range, 1-15 mm). Eighty-nine lesions had definitive diagnosis. Seventy-five lesions were proved to be malignant; seventy (93%) could be accurately diagnosed with coaxial percutaneous core biopsy samples. Fourteen lesions were proved to be benign; 10 (71%) were specifically diagnosed with biopsy samples. Among the 91 biopsies, the overall diagnostic accuracy was 88% (80 of 91 lesions). A pneumothorax occurred in 31 cases (34%), three (3%) of which necessitated placement of a chest tube. Postbiopsy hemoptysis occurred and resolved spontaneously in nine cases (10%).CONCLUSION: This technique provides a core biopsy specimen without the need for an on-site cytopathologist during the procedure. It has a high diagnostic accuracy and an acceptable rate of complications.
