UNASSIGNED: Bronchial foreign body aspiration is a life-threatening emergency. Largely, the published literature focuses on the removal of foreign bodies by bronchoscopy, while the surgical removal of endobronchial foreign bodies is rarely reported on. Thus, we presented a case of a bronchial foreign body that was successfully removed by a video-assisted thoracoscopic surgical (VATS) bronchotomy, after multiple failed bronchoscopic attempts.
METHODS: A 77-year-old male patient presented with a 2-month duration of a persistent cough and low-grade fever after undergoing dental treatment. Bronchoscopy revealed a dental crown surrounded by granulation tissue in the right basal bronchus. The patient was referred to our department for open surgery after undergoing multiple unsuccessful extractions. The bronchial foreign body was removed by a VATS bronchotomy. The postoperative course was uneventful, and the patient was discharged 2 days postoperatively without any complications.
UNASSIGNED: Most aspirated tracheobronchial foreign bodies can be removed through bronchoscopy; nonetheless, certain aspirated foreign bodies may require surgical intervention. Furthermore, the indications for bronchotomies encompass the failure to remove the foreign body despite repeated attempts, due to immobility, with or without distal bronchial placement. Thoracoscopy is beneficial in providing superior visualization, with an increased likelihood of post-bronchotomy recovery.
CONCLUSIONS: VATS bronchotomy is a safe and effective alternative for the removal of bronchial foreign bodies without sacrificing the functioning of the lung parenchyma.

Children and older adults are prone to unintentional foreign body aspiration. A 69-year-old man with fever and anorexia presented with obstructive pneumonia resulting from foreign body aspiration. Attempts to remove the foreign body using a bronchoscope failed due to its adhesion to the periphery of the bronchus. Although antibiotic therapy did not improve the obstructive pneumonia caused by the bronchial foreign body, surgery enabled an improvement. The surgical specimen showed similar pathological findings as the fine brown granular material observed in root granulomas occurring as a complication following leakage of root canal filling used in the treatment of dental caries. Therefore, the bronchial foreign body may have been a dental filling. Case reports describing surgical improvement of difficult-to-remove bronchial foreign bodies with concurrent infection are rare.

Oral care for patients with severe physical and intellectual disabilities is important to prevent the development of systemic diseases and maintain or improve their health. Foreign bodies accidentally aspirated into the respiratory tract can cause critical problems. To our knowledge, this is the first case report of aspiration of a broken tip of a disposable saliva ejector in a patient with severe physical and intellectual disabilities. The patient\'s strong bite broke off the ejector\'s tip during oral care. The foreign body was removed by flexible bronchoscopy without any complications. Such cases are sometimes asymptomatic or mildly symptomatic; thus, learning how to appropriately respond is essential for caregivers and family doctors. In addition, this device is widely used in clinical practice, and such risks should be widely known. Moreover, manufacturers should develop more robust equipment for oral care.

The age of predilection for foreign body aspiration into the lower airway shows a bimodal distribution, with the majority of cases occurring in children or infants and in the elderly. Although several pediatric airway foreign bodies have been summarized, in adults, bronchial foreign bodies are relatively uncommon. There are a variety of symptoms induced by airway foreign bodies, although the typical symptoms of some bronchial foreign bodies are cough. Bronchial foreign bodies, especially in the elderly, may have few symptoms and it is necessary for careful identification. Therefore, it is very important to carefully perform medical consultations about current and past medical history. Herein, we report a case of an elderly Japanese with obstructive pneumonia with a bronchial foreign body of fish bone with a long history of cough. It is known that people in some countries such as Japan have a habit of eating fish. Therefore, it is necessary to more carefully explore the possibility of some bronchial foreign body such as a fish bone, when we observe symptoms of persistent cough in such countries.

As cases of magnesium oxide pill aspiration are rare, the associated airway proinflammatory properties and appropriate analytic strategies remain unclear. An 81-year-old woman presenting with dyspnea was diagnosed with magnesium oxide pill aspiration. Computed tomography, a \"mixing test\" with levodopa, and a magnesium content analysis revealed a similar density between the foreign body and her prescribed magnesium oxide pill. The patient recovered without airway complications after foreign body removal. Clinicians should be aware of magnesium oxide tablets as potential bronchial foreign bodies in elderly patients because they may not dissolve without exposure to gastric juices.

Spruce branch is a rare radiolucent bronchial foreign body. Despite modern imaging tests and endoscopic examination, this foreign body is often detected only intraoperatively. This study enrolled 4 patients with spruce branch aspiration. In the 4th case, spruce branch was removed during rigid bronchoscopy that was associated with «lodging» type of foreign body. In two cases, spruce branch migrated to peripheral bronchial segments («extrusive» type) that required surgical treatment (thoracoscopy with resection of the right basal pyramid segments and wedge resection of the right lower lobe). The 3rd case was the most interesting. Initially, the foreign body was «underlying», but it migrated after partial endoscopic removal that finally required right-sided lower lobectomy. This report describes the peculiarities of clinical course and management of patients with a rare type of radiolucent bronchial foreign body - spruce branch.
Ветка елового дерева — редкий тип рентген-неконтрастного инородного тела бронхов. Несмотря на современные возможности лучевых и эндоскопических методов обследования, зачастую этот тип инородных тел обнаруживают только интраоперационно. Мы проанализировали 4 клинических случая лечения больных с аспирацией веткой хвойного дерева. В клиническом случае 4 инородное тело было полностью удалено при ригидной бронхоскопии, что определялось его нахождением в просвете бронха («залегающий» тип инородного тела). В 2 случаях еловая ветка мигрировала в периферические отделы трахеобронхиального дерева («экструзионный» тип), что потребовало хирургического лечения: в клиническом случае 1 выполнены видеоторакоскопия, резекция базальной пирамиды справа, в случае 2 — клиновидная резекция нижней доли правого легкого. Наиболее интересным нам представляется случай 3: изначально инородное тело было «залегающим», но после частичного удаления при фибробронхоскопии мигрировало, что в итоге потребовало выполнения видеоторакоскопии, нижней лобэктомии справа.
UNASSIGNED: В представленной серии клинических случаев мы хотели продемонстрировать особенности течения данной патологии и свой опыт ведения больных с аспирацией веткой хвойного дерева.

Pseudobronchial crista-like change is an unusual type of inflammatory granulation tissue hyperplasia in the endobronchial membrane caused by chronic retention of bronchial foreign bodies. Here, we report a case of pseudobronchial crista-like change in a 4-year-old boy who required admission for intermittent cough for >10 days and wheezing for 2 days. The main manifestation was persistent and non-healing lobar pneumonia. Initial electronic bronchoscopy showed cristae at the distal left main bronchus, which was misdiagnosed as bronchial opening stenosis. Repeat electronic bronchoscopy was performed after standard antibiotic treatment proved ineffective. Foreign bodies were observed at the opening of the basal branch of the left lower lobe. The left main bronchial cristae were clamped. The cristae appeared to be a pseudobronchial crista-like change caused by long-term retention of bronchial foreign bodies. After CT-confirmation of no abnormal blood supply at the cristae, the bronchial foreign bodies were removed, and the distal cristae of the left main bronchus were cut-off by laser, followed by balloon dilatation. To our knowledge, no similar cases have been reported so far in our review of domestic and foreign literature. Insufficient clinical understanding of Pseudobronchial Crista-like Change increase the risk of misdiagnosis and missed diagnosis. Detailed exploration and careful identification under bronchoscopy are helpful for the timely diagnosis and treatment of Pseudobronchial Crista-like Change.

Polycarbophil calcium (Polyful®; Mylan, Tokyo, Japan) is a stool stabilizer that absorbs liquid and swells to form a soft, bulky mass. A 75-year-old woman experienced sore throat and difficulty breathing immediately after taking the drug. Chest computed tomography showed a foreign body in the right intermediate bronchus. Bronchoscopy showed a white mass blocking the right intermediate bronchus. Since the mass was very fragile, we performed suctioning while breaking up the mass with a suction tube. The mass consisted of polycarbophil calcium. Since aspirated polycarbophil calcium swells and can obstruct bronchi, complete removal is crucial.
