Supplementary Material for: Single-Use or Disposable Flexible Bronchoscopy in Advanced Bronchoscopy Procedures: Experience in a Quaternary Referral Centre

<b><i>Background:</i></b> The development of single-use flexible or disposable bronchoscopes (SUFBs) has accelerated in recent years, with the reduced risk of infectious transmission and reduced need for endoscopy staffing particularly advantageous in the COVID-19 pandemic era. <b><i>Objective:</i></b> The objective of this study was to assess the performance of a novel single-use bronchoscope in an academic quaternary referral centre with on-site interventional pulmonology programme. <b><i>Methods:</i></b> With ethical approval in a quaternary referral centre, we prospectively collected data on sequential bronchoscopy procedures using The Surgical Company Broncoflex© range of SUFBs. Data collected included demographic, procedural, scope performance, user satisfaction, and complication parameters in a tertiary bronchoscopy service. <b><i>Results:</i></b> 139 procedures were performed by five pulmonology faculty from January to July 2021. The majority were carried out for infection (45%) and malignancy (32%). Most were performed in the endoscopy suite and 8% were COVID positive or suspected. Most procedures reported the highest score in satisfaction (85%) with technical limitations reported in 15% (predominately related to scope suction or inadequate image quality) reverting to a reusable scope in 2.8 %. <b><i>Conclusion:</i></b> In our subset of patients in a bronchoscopy unit, SUFBs are safe, and both routine and advanced bronchoscopy procedures can be performed with high satisfaction reported.**背景：** 近年来，一次性柔性支气管镜（single-use flexible bronchoscopes, SUFBs）的研发进程显著加快，其降低感染传播风险、减少内镜诊疗人员配置需求的优势在新冠疫情时代尤为凸显。 **目标：** 本研究旨在依托开展现场介入肺脏病学项目的学术型四级转诊中心，评估一款新型一次性支气管镜的临床性能。 **方法：** 本研究获得某四级转诊中心伦理委员会批准，前瞻性收集了使用The Surgical Company Broncoflex©系列一次性柔性支气管镜开展的连续支气管镜诊疗数据。本三级支气管镜诊疗中心所采集的数据涵盖人口统计学、操作流程、内镜性能、使用者满意度及并发症相关参数。 **结果：** 2021年1月至7月期间，5名肺脏病学执业医师共完成139例支气管镜诊疗操作。其中多数操作针对感染性疾病（45%）与恶性肿瘤（32%）开展，大部分操作在内镜诊疗室完成，8%的病例为新冠病毒核酸阳性或疑似感染者。针对操作满意度的评分显示，多数使用者给出满分（85%）；15%的操作报告存在技术局限性，主要与内镜抽吸功能不足或图像质量欠佳相关，其中2.8%的操作转而使用可复用支气管镜完成。 **结论：** 在本支气管镜诊疗中心的患者亚组中，一次性柔性支气管镜安全性良好，可顺利开展常规及进阶支气管镜诊疗操作，且使用者满意度较高。
