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...

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...

Tracheal replacement for the treatment of end-stage airway disease remains an elusive goal. The use of tissue-engineered tracheae in compassionate use cases suggests that such an approach is a viable option. Here, a stem cell-seeded, decellularized tissue-engineered tracheal graft was used on a compassionate basis for a girl with critical tracheal stenosis after conventional reconstructive techniques failed. The graft represents the first cell-seeded tracheal graft manufactured to full good manufacturing practice (GMP) standards...

BACKGROUND: Bronchopleural fistulae represent a relatively rare complication of pulmonary resection. For inoperable patients, several endoscopic procedures have been described. In the presence of large and chronic bronchopleural fistulae, persistent air leaks require a surgical therapy, while endoscopic airway stent represents a useful palliative treatment. OBJECTIVE: We describe the successful closure of large and chronic bronchopleural fistulae using an expandable polyvinyl alcohol (PVA) sponge and cyanoacrylate glue...

Mark A Varvares
Management of tracheostenosis in adult patients who are either medically unreconstructable due to significant comorbidities or surgically unreconstructable remains a challenge. The tracheal T-tube offers an excellent permanent solution to the problem of the unreconstructable trachea. This article reviews 3 patients who underwent tracheofissure and placement of a tracheal T-tube after failed prior attempts at repair of tracheal stenosis. The tracheal T-tubes have been maintained for 13, 15, and 36 years, and these patients have enjoyed adequate phonatory and respiratory functions with the T-tube plugged and functioning as an airway stent...

Tracheoesophageal fistulas (TEFs) often occur with esophageal or bronchial carcinoma. Currently, we rely on implantation of delicate devices, such as self-expanding and silicone stents, in the esophagus or trachea to cover the fistula and expand the stenosis in order to relieve patient pain. However, because each case is different, our approach may not be effective for every patient. Consequently, new devices and technology have emerged to address these situations, such as degradable stents, Amplatzer(®) devices, endobronchial one-way umbrella-shaped valves, and transplantation of mesenchymal stem cells...

PURPOSE: Airway stent placement is an effective treatment for the immediate palliation of malignant airway obstruction. However, restenosis caused by tumor ingrowth and/or overgrowth after stenting is common. The purpose of this study was to investigate the feasibility and safety of a novel self-expandable stent loaded with (125)I seeds in healthy beagle dog. MATERIALS AND METHODS: Under fluoroscopic guidance, forty-eight self-expandable airway stents loaded with (125)I seeds were perorally placed in the main trachea of 48 healthy beagle dogs, who were randomly divided into four groups (Group A: 0...

This case describes successful reconstruction of a long-segment tracheal defect using AlloDerm as the conduit for reconstruction. A 38-year-old woman who had undergone a thyroid lobectomy in 2011 presented several months later unable to swallow. Chest computed tomography results revealed a tracheal/esophageal mass and a subsequent bronchoscopy, and esophagogastroduodenoscopy results revealed an upper esophageal/tracheal mass with two areas concerning for fistula. She underwent a bronchoscopy with a tracheal stent and percutaneous endoscopic gastrostomy placement...

AIM: To determine the efficacy of dual Y-shaped covered airway stents to treat thoracic stomach-right main bronchus fistulae. MATERIAL AND METHODS: Fifteen patients who developed thoracic stomach-right main bronchus fistula after oesophageal cancer resection and postoperative irradiation were retrospectively analysed. All fistulae were close to the right upper lobe bronchus. Two Y-shaped covered airway stents were designed for each patient. Under radiographic guidance, one stent was placed from the right main bronchus into the bifurcation of upper lobe and intermediate bronchus, the other was placed from the trachea into both main bronchi...

The study's objective was to determine effects of relative size and placement location of endoluminal stents on incidence of complications and survival for canine tracheal collapse. Measurements were obtained on lateral radiographs before and after stenting to determine percent of the trachea occupied by the stent. These values were monitored over time and compared to complication rates and survival. Overall median survival time was 502 days. Six month survival rate was 78%, 1 yr survival was 60%, and 2 yr survival was 26%...

We have developed the algorithm for the choice of the surgical strategy for the treatment of chronic post-traumatic laryngeal stenosis with the purpose of enhancing the effectiveness of the management of the patients presenting with this condition. The proposed approach envisages obtaining anthropometric characteristics of the patients, determination of the type of his (her) neck and constitution, construction of the regressive models of the clinically significant laryngometric parameters based on the results of the clinical observations including the dimensions of the glottal fissure and the position of the vocal folds, calculations of the size of the autotransplant and the length of the T-shaped tube based on the results of the mathematical analysis of the anthropo- and organometric characteristics of the concrete patient, the laryngoplastic and prosthetic treatment of the newly formed laryngo-tracheal passage...

OBJECTIVE: Airway obstruction in children may be caused by conditions such as vascular compression and congenital tracheobronchomalacia. Obstructive pulmonary vascular disease may be a detrimental sequel for patients with congenital heart disease. We evaluate our own original external stenting technique as a treatment option for these patients. METHODS: Ninety-eight patients underwent external stenting (1997-2015). Cardiovascular anomalies were noted in 82 (83.7%)...
