BACKGROUND/PURPOSE: Silicone and metallic stents are not effective in children with tracheobronchial stenosis or tracheomalacia. Herein, we aimed to evaluate the clinical manifestations and histological reaction of rabbit trachea to the presence of a new poly(lactic-co-glycolic acid) with polyisoprene (PLGA/PI) polymer absorbable stent. METHODS: Fourteen adult white rabbits (weight, 3.0-3.5kg) were randomly assigned to three groups: Group I (n=6): PLGA/PI spiral stent; Group II (n=6): PLGA/PI fragment; and Group III (n=2): controls...

Tracheal stenosis caused by malignancy is a life-threatening complication. We performed stent therapy in two patients using the AERO™ stent, launched in late 2016 in Japan. One patient presented with stenosis of the trachea due to adenoid cystic carcinoma and the other with stenosis of the trachea due to esophageal cancer. Both patients showed improved symptoms, and no complications were identified. This is the first report of a favorable outcome with the use of this hybrid stent in Japan, and the findings suggest that insertion of the AERO hybrid stent is an effective way to improve patients' quality of life...

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...

A trachea is a tubular structure composed of smooth muscle that is reinforced with cartilage rings. Some diseases can cause sagging in smooth muscle and cartilaginous tissue. The end result is reduction (narrowing) of the trachea diameter. A solution to this problem is the use of tracheal stents, which are small tubular devices made of silicone. One is inserted into the trachea to prevent or correct its constriction. The purpose of tracheal stent use is to maintain cartilage support that would otherwise be lost in the airway...

Pulmonary artery sling (PAS) is a rare disease frequently associated with severe malacia and stenosis of the trachea. We present a two-day-old newborn that underwent urgent surgery for PAS and needed prolonged respiratory support afterward. Temporary airway stenting above the level of the tracheal bifurcation was performed five days after surgery to overcome severe airway obstruction caused by tracheomalacia and laceration of the tracheal mucosa after diagnostic bronchoscopy. Two days after the procedure, the child could be extubated and after two weeks the stent was removed without complications...

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...

Through a tracheostomy with a rigid esophagoscope in the esophagus, the authors simultaneously placed self-made magnetic twin stents in a critically ill patient with high tracheoesophageal fistula. The operation took 17 minutes. Oral nutrition was started immediately. The stents were checked and changed after the months 3, 7, and 14. At 18 months, a tracheal resection and esophageal reconstruction through a partial median sternotomy was completed successfully. The magnetic twin stent technique can temporize critically ill patients with an acquired nonmalignant tracheoesophageal fistula until they become operable...

Extended tracheo-bronchoplastic resection for lung cancer with carinal involvement ranks among technically demanding procedures. Despite certain progress in oncological therapy, this type of resection remains the only potentially curative treatment of NSCLC in this localization. However, given the severity of complications postoperative mortality is relatively high (711%). The main cause of death is tracheobronchopleural fistula complicated by thoracic empyema, bronchopneumonia and septic shock. If ARDS (acute respiratory distress syndrome) develops, the mortality rate rises up to 70%...

Silicone tracheobronchial stents are being increasingly used in a large number of patients for the treatment of tracheal stenosis. One very rare complication due to tracheobronchial stenting is bronchoesophageal fistula (BEF), which has been associated with the use of metallic stents. We report intraoperative management of a patient undergoing repair of a BEF, following previous insertion of a silicone Y-stent that is soft in texture and has not been implicated for this complication till date. In addition, misalignment of this silicone tracheobronchial Y-stent resulted in a tracheal mucosal bulge proximal to the stent that vanished after its removal...

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...
