Management of Tracheobronchial Stenoses With Endoprostheses: Experience With 103 Patients and 11 Models

Abstract

Endostenting is a safe and effective treatment for tracheobronchial stenoses. Removal and replacements were due to etiologies of the strictures, but not to the type of stent. Stenoses with an inflammatory component were prone to iterative stenting. Only benign diseases that are a contra-indication to open surgery should be treated by endoscopic stenting.

Determination of Predictive Factors of Tracheobronchial Prosthesis Removal: Stent Brands are Crucial

“…It ensures relatively safe access to the bronchial tree, allows better endoscopic visualization of the tumor, and gives more room to the operators. 2 In our opinion, suspension laryngoscopy under general anesthesia provides a wider range of possibilities than does bronchoscopy 21,22 (laser, electrocoagulation, dilation). Moreover, the instruments can be changed more quickly than with bronchoscopy, 22 because both hands are free.…”

Applied Surgical Anatomy of the Larynx and Trachea

“…There is almost no justification for using self-expandable metallic airway stents (SEMAS) in the management of benign stenoses of adult and child airways. Numerous reports of severe complications from indwelling SEMAS in the trachea and bronchi [6,17,24,36,37,39,61] are found in the literature. Among long-term complications, granulation tissue formation with subsequent restenosis, mucostasis, stent-migration, stent-fracture, as well as massive and lethal haemorrhage are described.…”

Numerical analysis of airflow alteration in central airways following tracheobronchial stent placement

“…As the development of material technology, the commercial silicon stent which could use rigid bronchoscopy to place the implants was proposed by Duman [2]. From that time, metallic airway stent insertion can achieve symptomatic relief in the majority of patients with airway obstruction, and mounting researches aimed at evaluating the effectiveness of metallic airway stents implants based on the change in lung function [3-8], clinical symptoms [9-12], comorbidity incidence [13,14], and survival rate [15-22], have been reported. However, it was difficult to examine or evaluate the efficacy in some patients with severe airway obstruction [23,24].…”
