Abstract

Background

Endobronchial Ultrasound (EBUS) has emerged as a crucial tool for diagnosing intrathoracic disorders, particularly in the staging of lung cancer. However, its diagnostic capabilities in the context of benign and rare diseases remain a subject of debate.

Aim

to investigate the diagnostic yield and safety of EBUS-transbronchial mediastinal cryobiopsy (EBUS-TMC) in comparison to EBUS-transbronchial needle aspiration (TBNA) for a broad spectrum of intrathoracic diseases.

Methods

a single-centre retrospective observational study conducted on 48 patients who underwent both EBUS-TBNA and endobronchial ultrasound-transbronchial mediastinal cryobiopsy (EBUS-TMC) in the same procedure between August 2021 and October 2023.

Results

The overall diagnostic yield of EBUS-TMC surpassed that of EBUS-TBNA (95.8% vs 54.1 %), notably excelling in the diagnosis of sarcoidosis (92.8% vs 78.5 %), rare mediastinal disorders (100% vs 0 %), hyperplastic lymphadenopathy (100% vs 0 %), and lymphoproliferative disease (100% vs 0 %). No significant differences were observed in the diagnosis of NSCLC and SCLC. Samples obtained through EBUS-TMC facilitated the acquisition of NGS and immunohistochemical analyses more readily.

Conclusion

EBUS-TMC may contribute to the precise diagnosis and subtyping of mediastinal diseases, especially lymphomas and rare mediastinal tumors, thereby reducing the number of non-diagnostic procedures.

EBUS 引导下的冷冻生物切片检查在胸腔疾病诊断中的应用

背景支气管内超声（EBUS）已成为诊断胸腔内疾病，尤其是肺癌分期的重要工具。目的研究 EBUS-经支气管纵隔冷冻活检术（EBUS-TMC）与 EBUS-经支气管针吸术（TBNA）相比，对多种胸腔内疾病的诊断率和安全性。方法对2021年8月至2023年10月期间同时接受EBUS-TBNA和支气管内超声-经支气管纵隔低温活检（EBUS-TMC）的48例患者进行了单中心回顾性观察研究。结果 EBUS-TMC 的总体诊断率超过了 EBUS-TBNA（95.8% vs 54.1%），尤其在诊断肉样瘤病（92.8% vs 78.5%）、罕见纵隔疾病（100% vs 0%）、增生性淋巴腺病（100% vs 0%）和淋巴增生性疾病（100% vs 0%）方面表现突出。在 NSCLC 和 SCLC 的诊断中未发现明显差异。结论EBUS-TMC有助于纵隔疾病，尤其是淋巴瘤和罕见纵隔肿瘤的精确诊断和亚型分类，从而减少非诊断性手术的数量。
