To describe operative techniques using rigid bronchoscopy and ferromagnetic bronchoscopic equipment to retrieve magnetic foreign bodies in distal tertiary bronchi beyond the reach of traditional optical instrumentation.
A 13-year-old presented to the Emergency Department following aspiration of three backing magnets from a magnetic nose ring. Chest radiographs demonstrated a 4 mm × 3 mm foreign body in the right lower lobe 0.5 cm from diaphragm on expiratory film. She was taken to the operating room for removal of an airway foreign body.
The foreign body was visualized with direct laryngoscopy followed by rigid bronchoscopy in the distal right lower tertiary bronchus. Attempts to pass optical instruments were limited both by distance of the object and size of instrumentation compared to the diameter of the tertiary bronchus. A salivary wire basket and ureteral stone retrieval basket were then passed with endoscopic visualization into the tertiary bronchus but were unable to engage the foreign body. An attempt was made to pass a 2 French Fogarty embolectomy catheter distally, but the catheter was too large to bypass the foreign body. Finally, ferromagnetic pulmonary rat tooth biopsy forceps were advanced into the tertiary bronchus and successfully attracted the magnetic foreign body for safe removal through our rigid bronchoscope.
We present a novel method of utilizing ferromagnetic flexible bronchoscopic instruments to safely remove magnetic foreign bodies in the tertiary bronchi beyond the reach of traditional bronchoscopic instruments. Laryngoscope, 135:920-922, 2025.
描述使用硬质支气管镜和铁磁性支气管镜设备的手术技术，以取出传统光学器械无法触及的远端三级支气管内的磁性异物。
一名13岁儿童因吸入磁性鼻环上的3颗背衬磁铁后被送往急诊科。胸部X线片显示，呼气片上右肺下叶距膈肌0.5厘米处有一个4毫米×3毫米的异物。她被送往手术室取出气道异物。
通过直接喉镜检查，随后在右肺下叶远端三级支气管进行硬质支气管镜检查，可见异物。与三级支气管直径相比，由于异物距离和器械尺寸的限制，光学器械难以通过。然后在内镜直视下将唾液线篮和输尿管结石取出篮送入三级支气管，但无法夹住异物。尝试将一根2法国Fogarty取栓导管向远端推进，但导管太大，无法绕过异物。最后，将铁磁性肺鼠齿活检钳推进三级支气管，成功吸引磁性异物，通过硬质支气管镜安全取出。
我们提出了一种利用铁磁性柔性支气管镜器械安全取出传统支气管镜器械无法触及的三级支气管内磁性异物的新方法。《喉镜》，2025年，第135卷：920 - 922页。
