Abstract

Background: Transbronchial lung cryobiopsy (TBLC) is a new technique that enables larger tissue collection than can be obtained by conventional transbronchial lung biopsy. TBLC is becoming popular worldwide and is performed for diffuse lung disease and lung cancer. However, only a few reports of TBLC have been published in Japan. This study was performed to evaluate the efficacy and safety of TBLC at our hospital and compare these findings with past reports.

Methods: From April 2018 to January 2020, 38 patients who underwent TBLC for diffuse lung disease at our hospital were evaluated with respect to age, sex, biopsy site, biopsy size, diagnostic disease, and complications.

Results: The patients who underwent TBLC were 20 men and 18 women with an average age of 63.7 years. The average sample size was 5.7 mm, and the diagnostic rate was 65.7% (25/38). Grade ≥2 complications included bleeding (15.8%), pneumothorax (2.6%), and atrial fibrillation (2.6%).

Conclusions: TBLC was considered to be useful for the diagnosis of diffuse lung disease and could be safely performed.

日本经支气管冷冻活组织检查治疗间质性肺病的可行性、实用性和安全性。

背景：经支气管肺冷冻活检术（TBLC）是一种新技术，与传统的经支气管肺活检术相比，它能采集到更多的组织。经支气管肺冷冻活检术正在全球范围内流行，可用于弥漫性肺部疾病和肺癌的治疗。然而，日本仅发表了几篇关于 TBLC 的报道。本研究旨在评估我院 TBLC 的疗效和安全性，并将这些结果与过去的报告进行比较：从 2018 年 4 月至 2020 年 1 月，对在我院接受 TBLC 治疗的 38 例弥漫性肺部疾病患者的年龄、性别、活检部位、活检大小、诊断疾病和并发症进行了评估：接受 TBLC 检查的患者中，男性 20 人，女性 18 人，平均年龄 63.7 岁。平均样本大小为 5.7 毫米，诊断率为 65.7%（25/38）。≥2级并发症包括出血（15.8%）、气胸（2.6%）和心房颤动（2.6%）：结论：TBLC被认为有助于诊断弥漫性肺部疾病，而且可以安全进行。
