We report a case of a nine-year-old boy with clinical evidence of foreign body (FB) aspiration with 3 months of delay in diagnosis. The bronchoscopy found soft tissue FB with surrounding inflamed granulation tissue at the entrance to the lateral segmental bronchus. Repeated attempts to remove the FB with flexible forceps were unsuccessful due to friable FB and granulation tissue. Ablation of the granulation tissue using nitrous oxide cryotherapy was then successfully performed and the distal and organic FB was extracted. Early diagnosis is important for minimizing granulation tissue development which complicates FB removal. Cryotherapy with a flexible bronchoscope is an option if organic FB cannot be removed using conventional bronchoscopic instrumentation.
我们报告一例9岁男孩，有异物吸入的临床证据，但诊断延迟了3个月。支气管镜检查发现，在外侧段支气管入口处有软组织异物，周围伴有炎性肉芽组织。由于异物易碎且伴有肉芽组织，多次尝试用可弯曲钳取出异物均未成功。随后成功地使用一氧化二氮冷冻疗法切除了肉芽组织，并取出了远端的有机异物。早期诊断对于尽量减少使异物取出复杂化的肉芽组织形成非常重要。如果使用传统支气管镜器械无法取出有机异物，可使用可弯曲支气管镜进行冷冻治疗。
