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%)...

A man aged 51 years was referred for tracheobronchial stenting after a poorly differentiated oesophageal carcinoma had progressed to cause stridor. Bronchoscopy revealed a left vocal cord palsy and tumour infiltration into the trachea. A tracheobronchial stent was placed, and after distal migration was endoscopically resited. Returning from theatre, the patient developed severe upper airway obstruction that progressed to cause CO2 narcosis and loss of consciousness. A rapid sequence induction was initiated, and a Glidescope revealed bilateral vocal cord palsy with severe oedema causing an inability to pass a tube or stylet...

Patients with distal esophageal pathology such as perforation, trachea-esophageal fistulae, and/ or obstructing gastroesophageal junction tumor present a challenging situation in terms of feeding access where an esophageal stent is placed across the gastroesophageal junction. In order to allow simultaneous gastric decompression and post-pyloric feeds without significant reflux up through the stent, a gastrojejunostomy (GJ) tube is a viable option. We hereby describe a hybrid approach to placing these GJ tubes in this cohort of patients using simultaneous laparoscopy, endoscopy, and fluoroscopy with minimal manipulation of the stent itself...

The trachea has a complex anatomy to fulfill its tasks. Its unique fibro-cartilaginous structure maintains an open conduit during respiration, and provides vertical elasticity for deglutition, mobility of the neck and speech. Blood vessels pierce the intercartilaginous ligaments to perfuse the ciliated epithelium, which ensures effective mucociliary clearance. Removal of a tracheal segment affected by benign or malignant disease requires airtight restoration of the continuity of the tube. When direct approximation of both tracheal ends is no longer feasible, a reconstruction is needed...

Endobronchial stent placement is a novel therapy for treatment of iatrogenic tracheal tears. A review of the available literature shows surgery and long-term intubation being the established treatment strategy. We describe the case of a 64-year-old woman with a tracheal rupture following endotracheal intubation for routine surgery. Pneumo-mediastinum and chest pain were the predominant symptoms. She was treated with a covered self-expandable metal stent that closed the tear and led to immediate symptom relief...

Objective: To study the effect of self-expanding bare metal stents on the trachea of dogs, and therefore to provide useful information for choice of airway stents by interventional physicians. Methods: In this experiment, 8 beagles were randomly divided into 4 groups. Four self-expanding metal stents of different diameters (16, 18, 20 and 22 mm, respectively) were placed in the trachea of these beagles for 3 months and their impacts on normal trachea were observed. Results: In the 16 mm stent group (stent-to-airway diameter ratio 103%), good epithelialization was observed and the tracheal structure had no significant damage...

BACKGROUND: Bare metal stents may cause complications like fibrous encapsulation, granulation and tracheal stenosis. We investigated the behaviour of three commercially available stents in vivo (rabbits) and in vitro (coculture of those stents with epithelial and fibroblast cell lines). Also, we investigated whether development of tracheal stenosis could be predicted by any biological marker. MATERIALS AND METHODS: The tracheae of 30 rabbits were implanted with either nitinol stents, with or without paclitaxel elution, or a cobalt-based stent...

One of the major problems in end-stage bronchotracheal cancer is stenosis of the upper airways, either due to luminal ingrowth of the tumor or mucus plugging. Airway stents that suppress tumor ingrowth and sustain mucociliary transport can alleviate these problems in end-stage bronchial cancer. We evaluated different types of polymeric covers for a tissue engineered airway stent. The distinguishing feature of this stent concept is that respiratory epithelial cells can grow on the luminal surface of the stent which facilitates mucociliary clearance...

OBJECTIVE: The solution of severe tracheobronchial obstructions in early childhood means a great challenge. Biodegradable stents were intended to be a minimally invasive temporary solution which may decrease the number of interventions and limit the possible complications of stenting procedures. However, our first experiences have brought out a new, - especially in childhood - potentially life-threatening complication of this concept. METHODS: Five SX-ELLA biodegradable polydioxanone stents was applied in three patients because of severe tracheobronchial obstruction: congenital tracheomalacia (7 day-old), acquired tracheomalacia (10 month-old), and congenital trachea-bronchomalacia (10 month-old)...

BACKGROUND: Currently available silicone and metallic stents for tracheal stenosis are associated with many problems. Granulation proliferation is one of the main complications. The present study aimed to evaluate the efficacy of paclitaxel drug-eluting tracheal stent in reducing granulation tissue formation in a canine model, as well as the pharmacokinetic features and safety profiles of the coated drug. METHODS: Eight beagles were randomly divided into a control group (bare-metal stent group, n = 4) and an experimental group (paclitaxel-eluting stent group, n = 4)...

Occurrence of bronchial artery aneurysm is rare, and it has been detected in less than 1 % of all selective bronchial arteriography cases. Here, we present a case of a bronchial artery aneurysm caused by a tracheal stent migration. A 59-year-old man was operated on for esophageal cancer, where an esophageal-tracheal fistula occurred 1 week after operation. Surgical repair of the esophageal-tracheal fistula was performed using a muscle flap, but this not results in fistula closure. Consequently, a self-expanding covered metallic tracheal stent was implanted for rescue, and this resulted in fistula closure...

OBJECTIVES: Repair of laryngotracheal stenosis with pronounced side-to-side narrowing and involvement of the glottis is challenging and usually requires laryngotracheal reconstruction with rib cartilage interpositions. This technique, as first described by Couraud, needs prolonged postoperative stabilization with Montgomery T-tubes, imposing significant morbidity and discomfort on patients. We describe our initial experience with a modified laryngotracheal reconstruction technique that avoids the need for prolonged postoperative stenting...
