BACKGROUND: Airway stenting has been reported to be useful for patients with malignant airway stenosis as a bridge to tumor-specific therapy, such as chemotherapy and radiation therapy, as well as palliative therapy. However, its role in patients with small-cell lung cancer (SCLC), the most aggressive lung cancer subtype, is unclear. We investigated the efficacy of airway stenting for patients with airway stenosis resulting from SCLC. METHODS: All stenting procedures were performed using both rigid and flexible bronchoscopes under general anesthesia...

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...

Anastomotic airway complications are a severe cause of morbidity after lung transplantation, included the dehiscence of the bronchial anastomosis. We present a case of dehiscence treated by placing an uncovered metal stent into the main bronchus. We usually use this procedure for bronchial stenosis, but in this case the stent favored the growth of granulation tissue and so the closure of the dehiscence. This surgery is minimally invasive and it may be an alternative to open surgery, without preclude it in case of failure...

Bronchobiliary fistula (BBF) is a rare condition, defined as an abnormal communication between the bronchial system and the biliary tree. Patients with this condition usually present with massive biliptysis, and the mortality rate is high. BBF has been reported to occur in patients with congenital conditions, complications of trauma, hepatic abscesses and biliary tract obstruction (surgical as well as non-surgical). However, to the best of our knowledge, BBF as a complication of transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) has not been reported to date...

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...

Case summary: Bronchial stents may be useful to relieve clinical signs of extraluminal compression. Herein we describe a case which, to our knowledge, is the first cat where bilateral bronchial stents have been used clinically. Respiratory signs of principal bronchial compression were alleviated after the stent procedure. Minor complications occurred, specifically: severe hypoxia during stent deployment; a transient, self-limiting postoperative pneumothorax possibly associated with ventilation-induced lung injury; bronchopneumonia (possibly pre-existing); and transient worsening of cough postoperatively...

OBJECTIVES: To assess the placement, surveillance management and long-term outcomes of the tracheobronchial (TB) balloon expandable metallic stent (BEMS) managed by therapeutic flexible endoscopy (TFE). METHODS: This is a retrospective review and analysis of all computerized medical records and related flexible endoscopy videos of pediatric patients who received TB BEMS during 20 years period, from January 1997 to December 2016. TFE techniques with forceps debridement, balloon dilatation and laser ablation were used to implant stents, perform regular surveillance, maintain their functions, and expand the diameters of BEMS...

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...

Bronchial obstruction is infrequent in the child. The main cause is malacia or benign stenosis. Management alternatives range from conservative treatment to complex surgical and/or endoscopic techniques. Placement of a stent can play a key role in situations where there is no other therapeutic option. However, the ideal stent is not yet available. In the last few years, progress has been made in the development and characterization of novel biodegradable materials in order to overcome the drawbacks of traditional stents made of silicone or metal...

BACKGROUND: In patients with bronchial obstruction estimating the location of the maximal obstruction is crucial for guiding interventional bronchoscopy. However, flow-volume curves cannot discriminate between the right and left lungs. OBJECTIVES: The aim of this study was to physiologically evaluate bronchial obstruction during interventional bronchoscopy. METHODS: We prospectively measured lateral airway pressure (Plat) at either side of the obstruction using a double-lumen catheter (pressure-pressure [P-P] curve) simultaneously to assess the degree of bronchial obstruction in 22 patients...

OBJECTIVES: We describe the way we treated 7 children with critical long-term complications after metallic balloon-expandable stenting in the left mainstem bronchus. METHODS: Endoscopic follow-up included a first bronchoscopy 3 weeks after stenting, then monthly for 3 months, every 4-6 months up to 1 year and at scheduled times to calibrate stent diameter up to final calibration. When major complications occurred, patients underwent chest computed tomographic angiography...

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...

BACKGROUND: Tracheal and bronchial stenosis is a life-threatening condition causing difficulty in breathing and even severe respiratory distress. The silicone tracheobronchial stents were placed using the rigid bronchoscopy into the trachea of severe dyspneic patients and they exhibited symptomatic improvement as well as a rise in the saturation of oxygen. The bronchial stents were applicable to many extensive malignant airway stenosis patients, such as those with esophageal cancer, lung cancer, and laryngeal cancer...

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...

A 72-year-old woman with a history of malignant lymphoma was referred to our hospital for the treatment of a bronchial artery aneurysm. Computed tomography (CT) scan showed a round, 30 mm-diameter fusiform aneurysm with two tortuous inflow arteries. We deployed thoracic stent grafting to cover the orifice of the two inflow arteries without transcatheter bronchial arterial embolization. Postoperative CT scan revealed complete thrombosis of the aneurysm. Although further follow-up is mandatory, this may be considered a viable treatment option in cases wherein the bronchial artery aneurysm is anatomically difficult to treat...

The purpose of the present study was to develop gefitinib-loaded polymeric foams that can be used as coating of drug-eluting stents for palliative treatment of bronchotracheal cancer. Release of such an anticancer drug from such stent coating can retard tumor regrowth into the bronchial lumen. Gefitinib-loaded polyurethane (PU) foams were prepared by embedding either gefitinib micronized crystals or gefitinib-loaded poly(lactic-co-glycolic acid) microspheres in water-blown films, with up to 10% w/w loading for gefitinib microcrystals and 15% w/w for gefitinib microspheres (corresponding to 1...

Ruptured thoracic aortic aneurysms, having aorto-bronchial or pulmonary parenchymal fistulations, are life-threatening conditions, and current surgical treatment results are not satisfactory. Herein, we describe a 69-year-old man with a ruptured thoracic aortic aneurysm and aorto-pulmonary parenchymal fistulation that was successfully treated using a staged repair. The first stage involved an emergency thoracic endovascular aortic repair for salvage and the second stage involved radical pulmonary parenchymal repair with removal of the stent graft and aortic reconstruction for long-term survival...
