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...

Changzhi Zhou, Yi Hu, Yang Xiao, Wen Yin
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%)...

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...
