During thoracoscopic pulmonary segmentectomy, identification of the target segmental bronchus can occasionally be difficult. We devised a new method to overcome this difficulty. Immediately before surgery, the target segmental bronchus was marked with indocyanine green using bronchoscopy and identified intraoperatively using near-infrared fluorescence thoracoscopic imaging. Eleven consecutive patients underwent thoracoscopic segmentectomy between August 2023 and April 2024. The target segmental bronchi were successfully marked with indocyanine green in 10 cases (success rate: 90.9%) and clearly identified during surgery. In all cases, the target segmental bronchi were correctly divided without the use of intraoperative bronchoscopy; thus, the planned segmentectomies were accomplished without conversion to lobectomy. This novel technique using indocyanine green can facilitate identification of the target segmental bronchus during thoracoscopic segmentectomy.
在胸腔镜肺段切除术中，有时很难识别目标段支气管。我们设计了一种新方法来克服这一困难。在手术即将开始前，使用支气管镜用吲哚菁绿标记目标段支气管，并在术中使用近红外荧光胸腔镜成像进行识别。2023年8月至2024年4月期间，连续11例患者接受了胸腔镜肺段切除术。10例患者成功用吲哚菁绿标记了目标段支气管（成功率：90.9%），并在手术中清晰识别。在所有病例中，未使用术中支气管镜就正确地切断了目标段支气管；因此，按计划完成了肺段切除术，无需转为肺叶切除术。这种使用吲哚菁绿的新技术可以在胸腔镜肺段切除术中促进目标段支气管的识别。
