INTRODUCTION: Lung agenesis is a rare disorder with a variable, but potentially very bad clinical course. It necessitates complex clinical management, especially in life-threatening situations. CASE REPORT: We describe a case of a 6-month-old girl with right lung agenesis who required venovenous extracorporeal membrane oxygenation (VV-ECMO) due to pneumonia complicated by exacerbated previously diagnosed left main bronchus stenosis. The stenosis was resolved by endobronchial intervention and X-ray-guided stent insertion, which enabled weaning from ECMO and was aimed at preventing such a life-threatening respiratory failure in the future...

RATIONALE: Airway stabilization for severe, symptomatic tracheobronchomalacia (TBM) may be accomplished by silicone Y-stent placement. Common complications of the Y-stent include mucus plugging and granulation tissue formation. PATIENT CONCERNS: We describe a rare case of massive hemoptysis originating from a silicone Y-stent placed for TBM. DIAGNOSES: An emergent bronchoscopy showed an actively bleeding, pulsatile vessel at the distal end of the left bronchial limb of the Y-stent...

OBJECTIVES: This study was designed to establish a porcine model of reversible obstruction of endobronchial foreign body (FB) and to assess the natural pulmonary reexpansion process using radiology and histopathology after removal of the bronchial FB. METHODS: A metal stent was placed in the right lower lobe bronchial lumen of 15 pigs by bronchoscopy and removed after 2 weeks of stent retention. Animals were divided into two groups (group I and II), based on when they were sacrificed (week 2 or week 4) after stent removal...

BACKGROUND: Prolonged air leak (PAL) is a life-threatening condition that can present either as bronchopleural fistula, or alveolar-pleural fistula (APF). Although numerous bronchoscopic treatments are described, they are either expensive, not widely available in the developing world or have limited success. We describe our experience with a novel customized endobronchial silicone blocker (CESB) for PAL treatment. METHODS: This is a retrospective study of PAL patients who underwent CESB placement...

Paediatric airway endoscopy is accepted as a diagnostic and therapeutic procedure, with an expanding number of indications and applications in children. The aim of this European Respiratory Society task force was to produce a statement on interventional bronchoscopy in children, describing the evidence available at present and current clinical practice, and identifying areas deserving further investigation. The multidisciplinary task force panel performed a systematic review of the literature, focusing on whole lung lavage, transbronchial and endobronchial biopsy, transbronchial needle aspiration with endobronchial ultrasound, foreign body extraction, balloon dilation and occlusion, laser-assisted procedures, usage of airway stents, microdebriders, cryotherapy, endoscopic intubation, application of drugs and other liquids, and caregiver perspectives...

A case of tracheobronchial stenosis due to tuberculosis in a young woman is presented. Compromised pulmonary function due to near-total obstruction of the proximal left main bronchus was diagnosed. Treatment options included surgical resection, endobronchial dilation or stenting, and argon photocoagulation. An approach was chosen to address symptoms without aggressive resection or commitment to stenting. She remains monitored and, while possibly committed to future intervention, no bridges have been burned with respect to more definitive and invasive therapies...

We evaluated principal risk factors and different therapeutic approaches for post-pneumonectomy bronchopleural fistula (BPF), focusing on open-window thoracostomy (OWT). We retrospectively reviewed all patients treated by pneumonectomy for lung cancer from 1999 to 2014; we evaluated preoperative, operative, and postoperative data; time between operation; and fistula formation, size, treatment, and predicting factors of BPF. Cumulative incidence curves for the development of BPF were drawn according to the Kaplan-Meier method...

Post-tuberculosis bronchostenosis (PTBS), a complication of endobronchial tuberculosis is currently treated by bronchial stenting. However, in cases of angulated bronchial stenoses, difficulty is often encountered in stent insertion and maintenance, resulting in stent migration, granulation tissue overgrowth, and restenosis. To accommodate the angulated alignment of the stenosis, we devised an "angulated stent"-a novel improvisation of the conventional stent via splicing and suturing to achieve a resultant angulated shape...

The lungs are the most common sites of metastases from non-pulmonary malignancies. On the other hand, endobronchial metastases are rare. Various tumors have been associated with endobronchial metastasis, most commonly renal, breast and colorectal cancer. Advanced rectal cancerwith lung metastasis is common. However, endobronchial metastasis without lung metastasis of rectal cancer is rare, and easily misdiagnosed. We report one case of postoperative rectal cancer with endobronchial, pleuralcavity, pericardial cavitymetastasis, giving the comprehensive treatment of bronchial stentimplantation, chemotherapy, targeted drugs and remission...

More than half of primary lung cancers are not resectable at diagnosis and 40% of deaths may be secondary to loco-regional disease. Many of these patients suffer from symptoms related to airways obstruction. Indications for therapeutic endoscopic treatment are palliation of dyspnea and other obstructive symptoms in advanced cancerous lesions and cure of early lung cancer. Bronchoscopic management is also indicated for all those patients suffering from benign or minimally invasive neoplasm who are not suitable for surgery due to their clinical conditions...

The use of venovenous extracorporeal membrane oxygenation (VV-ECMO) has traditionally been limited to a narrow set of clinical circumstances, such as acute hypoxic respiratory failure, submassive pulmonary embolism, and cardiopulmonary collapse. Within the pediatric population, there have been cases of VV-ECMO in the context of extrinsic airway compression by a mediastinal mass, typically in the setting of either a lymphoma or germ cell tumors. However, the use of VV-ECMO for adults with extrinsic airway compression is comparatively limited...

There is a dearth of data on management of anastomotic airway dehiscence following lung transplantation. Herein we report a case of successful conservative management of an anastomotic airway dehiscence after cadaveric donor lung transplantation. A 41-year-old woman with primary ciliary dyskinesia underwent cadaveric bilateral lung transplantation without cardiopulmonary bypass. On the postoperative day 25, left pneumothorax developed and bronchoscopy demonstrated a localized anastomotic dehiscence at the left main bronchus...

Tuberculosis (TB) is one of the leading causes of morbidity and mortality worldwide. Early diagnosis and treatment are key to prevent Mycobacterium tuberculosis transmission. Bronchoscopy can play a primary role in pulmonary TB diagnosis, particularly for suspected patients with scarce sputum or sputum smear negativity, and with endobronchial disease. Bronchoscopic needle aspiration techniques are accurate and safe means adopted to investigate hilar and mediastinal lymph nodes in cases of suspected TB lymphadenopathy...

Central airway obstructive infections (CAOI) are challenging medical conditions that may represent an advanced and complicated process of ongoing infections. The epidemiology of CAOI is unknown as well as the pathophysiology and the mechanism of development. This is due to sparse data in the literature that consists mainly of case reports and retrospective case series. CAOI can be caused by fungal, bacterial, parasitic and viral infections. Most patients with CAOI can be diagnosed clinically and with chest imaging, which demonstrate obstruction of the central airways...

In recent years, there have been many reports about the efficacy of stenting for central bronchial stenosis. When central bronchial stenosis is due to metastasis of a malignant tumor to the trachea and/or bronchi (endobronchial metastasis: EM), it is classified as "narrow EM" and "broad EM." [1] We managed two patients in whom bilateral stent placement was required for narrow and broad EM arising from colorectal cancer. Case 1: In September 2011, a 66-year-old man underwent low anterior resection for advanced colorectal cancer associated with unresectable liver metastasis...

INTRODUCTION: Stents have been used for quite some time for the treatment of benign and malignant airway stenosis. Silicon stents are preferred for benign situations, whereas metallic self-expanding stents are preferred for malignant comorbidities. PATIENT AND METHODS: In general, stents can be placed in different approach directions, although in pulmonary medicine it is logical to apply only antegrade techniques - until now. A 63-year-old patient, 168 cm height and 53 kg weight on referral, suffered chronical diseases...
