We present the case of a fistula between the trachea and the esophagogastric anastomosis in a 58-year-old male after esophagectomy. A Hem-o-Lok clip used at the time to ligate the azygos vein was discovered by esophagoscopy and bronchoscopy to be eroding into the both structures. A covered self-expandable Y-shaped metallic tracheobronchial stent was customized with a 3D printed airway model and inserted in place, with endoscopic injection of fibrin glue to the anastomotic site. 64 days after implantation, the stent was withdrawn with complete healing of the fistula...

OBJECTIVES/HYPOTHESIS: Current techniques for airway characterization include endoscopic or radiographic measurements that produce static, two-dimensional descriptions. As pathology can be multilevel, irregularly shaped, and dynamic, minimal luminal area (MLA) may not provide the most comprehensive description or diagnostic metric. Our aim was to examine the utilization of computational fluid dynamics (CFD) for the purpose of defining airway stenosis using an ovine model of tissue-engineered tracheal graft (TETG) implantation...

Long-segment tracheal reconstruction remains a challenge. The ideal tracheal substitute should be an epithelialized tube to prevent stenosis and sufficiently rigid to maintain airflow patency. An autologous technique using a radial forearm free flap reinforced by rib cartilage has been recently described for tracheal reconstruction. We report here two cases of complex tracheal reconstruction with a modification of this technique, which consists of the creation of two independent skin paddles to allow the reconstruction of the trachea and a second adjacent defect (eg, cervical skin, esophagus)...

Malignant stricture and fistula of the esophagus and tracheobronchus adversely affect the quality of life(QOL)in patients with advanced esophageal cancer. Stenting is one ofthe therapies available for these patients. We investigated the outcomes ofesophagus and tracheobronchial stenting in our institution. Eight patients with advanced esophageal cancer underwent double stenting from 2010 to 2016. Among them, 4 patients underwent double stenting as planned. One patient underwent an emergency tracheal stenting because ofstenosis ofthe trachea caused by esophageal stenting...

OBJECTIVES: Currently, most of the artificial airway organs still require scaffolds; however, such scaffolds exhibit several limitations. Alternatively, the use of an autologous artificial trachea without foreign materials and immunosuppressants may solve these issues and constitute a preferred tool. The rationale of this study was to develop a new scaffold-free approach for an artificial trachea using bio-3D printing technology. Here, we assessed the circumferential tracheal replacement using scaffold-free trachea-like grafts generated from isolated cells in an inbred animal model...

BACKGROUND: Stenting of airway stenosis is a common procedure in specialized centers. The aim of this study was to summarize our clinical experience in ventilation strategy and anesthesia management of patients undergoing urgent tracheal stenting. METHODS: Clinical data of 22 patients with severe tracheal stenosis who underwent urgent endoscopic placement of a tracheal stent during a 2-year period were retrospectively reviewed. The efficacy and safety of different ventilation strategies and veno-arterial extracorporeal membrane oxygenation (ECMO), individualized based on the cause and location of tracheal narrowing, were evaluated...

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...

Relapsing polychondritis (RP) is a rare systemic autoimmune disease that affects cartilaginous structures. RP causes tracheobronchomalacia (TBM) by affecting the bronchial cartilage. TBM is a fatal condition characterized by excessive weakening of the walls of the trachea and bronchi. We herein report a case of a 73-year-old man who experienced sudden respiratory failure due to TBM caused by RP. Immunosuppressive treatment did not improve his respiratory failure. Multiple metallic stentings dramatically improved his severe airway symptoms...

Endovascular treatments have become increasingly common for patients with a variety of thoracic aortic pathologies. Although considered less invasive than traditional open surgical approaches, they are nonetheless complex procedures. Patients undergo manipulation of an often calcified aorta near the origin of the carotid and subclavian vessels and have stents placed in a curved vessel adjacent to a perpetually beating heart. These stents can obstruct blood flow to the spinal cord, induce an inflammatory response, and in rare cases erode into the adjacent trachea or esophagus...

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...

BACKGROUND: Tracheoesophageal fistula (TEF) is a rare but life-threatening complication after esophagectomy. It has a high mortality rate and often leads to severe aspiration pneumonia. Various types of surgical repair procedures have been reported, but the optimal management of TEF is challenging and controversial. Treatment should be individualized to each patient. CASE PRESENTATION: A 66-year-old female underwent transthoracic esophagectomy with gastric tube reconstruction and an intrathoracic anastomosis for esophageal cancer...

We describe the case of a boy with spondyloepiphyseal dysplasia congenita. At birth, he experienced severe respiratory distress necessitating tracheotomy. Endoscopy done because mechanical ventilation failed to resolve desaturations disclosed severe tracheo-bronchomalacia. A Polyflex silicone stent was placed in the trachea (replaced by Y-Dumon stent) and 2 Palmaz metallic stents in the mainstem bronchi (overlapped with 2 Jomed stents 5 years later). Airway stenting guaranteed a suitable respiratory status and allowed a child who was expected to die at birth, to reach 13...

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...
