A 52-year-old man developed a right pneumothorax during treatment for COVID-19. In a previous case report concerning this patient, his recovery was achieved through implanting four endobronchial Watanabe spigots (EWS) in the right B1 and B3 in two phases and spraying N-butyl-2-cyanoacrylate (NBCA). One year later, EWS removal was planned. He was intubated under bronchoscopic guidance, and the right upper lobe was observed. The right B1 and B3 inlets were found to be covered with granuloma. Despite the presence of a nylon thread for easy retrieval and partial debridement of the granulation, removal of the implanted EWS in the right B1 and B3 using grasping forceps, basket forceps, and two types of balloons under fluoroscopic guidance was challenging. NBCA spraying is a possible cause of foreign body granuloma formation. Therefore, careful consideration of the indications for the combined EWS-NBCA procedure is necessary.
一名52岁男性在COVID-19治疗期间发生了右侧气胸。在之前一篇关于该患者的病例报告中，通过分两个阶段在右侧B1和B3植入四个支气管内渡边栓子（EWS）并喷洒N-丁基-2-氰基丙烯酸酯（NBCA），他实现了康复。一年后，计划取出EWS。在支气管镜引导下对他进行插管，并观察右上叶。发现右侧B1和B3入口被肉芽肿覆盖。尽管有尼龙线便于取出和对肉芽组织进行部分清创，但在荧光透视引导下使用抓钳、篮式钳和两种球囊取出右侧B1和B3中植入的EWS具有挑战性。喷洒NBCA可能是异物肉芽肿形成的原因。因此，必须仔细考虑EWS-NBCA联合手术的适应证。
