Foreign-body excretion is a bioresponse of the human body. Bronchial foreign bodies commonly occur through aspiration or inhalation. We present a rare case of the excretion of a foreign body through the bronchial stump 19 months after pneumonectomy.

Clinical summary

|---|
A 52-year-old man had a high fever and chest discomfort. He underwent a left extrapleural pneumonectomy for malignant pleural mesothelioma 19 months earlier. He received postoperative chemotherapy, which consisted of 4 cycles of cisplatin, doxorubicin, and cyclophosphamide, and sequential radiation therapy for the entire hemithorax of 56 Gy in total.1,2 Blood count showed luekocytosis, and chemistry showed an increased C-reactive protein level. Chest radiography showed no abnormal lesions except for left-side opacity after pneumonectomy. Computed tomography of the chest and the abdomen showed no evidence of recurrence of malignant pleural mesothelioma. Culture of thoracentesis fluid showed no growth of microorganisms. Bronchoscopic examination revealed a foreign body, a whitish cottony material, at the left main bronchial stump (Figure 1). Endoscopic extraction with forceps identified a hemostat of oxidized cellulose (Figure 2). After the extraction, a blue suture was translucently identified in the mucosa of the bronchial stump. Bronchopleural fistula was not seen during or after the extraction. Culture of the material revealed Haemophilus species. After the removal of the infected foreign body, the patient recovered quickly and has been doing well for 3 years.

The bronchial stump at the left extrapleural pneumonectomy was hand sutured with interrupted polypropylene sutures (3-0 Prolene; Ethicon Inc, Somerville, NJ) and reinforced with a pedicled intercostal muscle by using the same polypropylene sutures for bronchus. On the next day, the patient underwent a re-exploration of the thorax as a result of the excessive blood loss. After hemostasis was obtained, cotton-type oxidized cellulose (Oxycel; Sankyo Co, Tokyo, Japan) was inserted into the mediastinum as a hemostat. Bronchoscopic examination 4 weeks after the pneumonectomy showed normal findings at the bronchial closure. For 19 months of postoperative follow-up, the patient had been without any symptoms of bronchopleural fistula, and chest radiography had never shown an air-fluid level in the left thorax. The bronchial stump should have been airtight since the extrapleural pneumonectomy.

In the literature most foreign bodies found in the airway are the result of aspiration or inhalation. On the other hand, several bronchial foreign bodies that were not inhaled have been reported. Migration of shrapnel from the pulmonary parenchyma into a bronchus 64 years after the injury was reported.3 Two foreign bodies with uncommon ways of entry were removed with a bronchoscope: one was a bullet that eroded in the right lower bronchus after having penetrated through a wound in the chest wall, and the other was a fragment of circular saw lodged in the right main bronchus after penetration through a wound in the neck.4 Recent literature also described expectoration of titanium staples in 3 patients many months after volume-reduction surgery for pulmonary emphysema.5 Jackson and Jackson6 mentioned that foreign bodies, especially metallic ones that cause little specific reaction, can reach the bronchi through penetration of the chest wall. However, few nonmetallic foreign bodies migrating into the airway have been reported.
Our patient appeared to have excreted a hemostat of oxidized cellulose from the thoracic cavity into the endobronchial lumen through the sutures of the bronchial stump. The foreign-body reaction of cellulose has been known to be mild in in vivo experiments.7 Although the mechanisms of the migration remain unknown, we would provide evidence of a rare nonmetallic foreign body in the airway through the bronchial stump.
