Tracheobronchial Stents Positioning
Abstract
Tracheobronchial stents are devices meant to open collapsed airways. A stenosis or a narrowing of the light can be produced by many factors: lung cancer, metastatic cancers, infections, lymphomas, tuberculosis, abnormal granulation tissue, etc.
Rigid Bronchoscopy
Abstract
Rigid Bronchoscopy is a mechanism that permits the physician enter to the airway and it also permits the access of larger instruments and cameras to determine and treat conditions in that area.
Classification of medical device using different Machine Learning techniques

Physicist – Machine Learning Engineer.
Abstract
In this paper, a classification was made of three classes of medical devices manufactured by Stening®. The classification was made using three machine learning algorithms. These algorithms were Support Vector Machines, Logistic Regression and Decision Tree. With this study Stening® aims to make their products more known and that one can have a more technical vision of these.

Abstract
This is the first paper of a more ambitious project by Stening® which goal is to revolutionize the market and production in the field of medicine and custom prostheses. In this very first work we train a neural network to be able to distinguish six different kinds of devices. The results obtained are very encouraging and demonstrate the potential that this type of technology has in the future of medicine.
Tracheal Prosthesis Prolonged Implant: 10 Years

Head of Bronchoscopy service. Enrique Tornu Hospital. Buenos Aires. Argentina
Abstract
We analysed the extracted stent from a patient with benign tracheal stenosis who had a stent for over ten years, in comparison with a new disposal, and we performed simulation “aging” tests in the laboratory. We determined functional conditions and analysed factors of therapeutic failure. We propose changing modalities in endo-surgical treatment of tracheal stenosis.
Sinuous tracheal fissure

Respiratory endoscopy. Tornú Hospital. Buenos Aires. Argentina
Case description
It is a 29-year-old male patient. He was hospitalized for severe traumatic brain injury and subjected to orotracheal intubation for mechanical respiratory assistance. After 8 days, a tracheostomy was performed and continued on ARM for a total of 21 days. He remained with a nasogastric tube for three weeks.
Endoscopic Signs. Description of two new signs

Pulmonologist, Bronchoscopist, Chief of Respiratory Endoscopic Department, Hospital Enrique Tornú, Buenos Aires.
Abstract
The paper describes two new endoscopic signs which can be useful in the use of diagnostic bronchoscopy. This is an essay on particular anatomic and functional circumstances suggesting the presence of a pathology which cannot be seen by the bronchoscopist. These two signs are the Bubble Sign and the Black Hole Sign. The Bubble Sign is observed when the airflow is absent in a subsegmental bronchus leading to a peripheral pulmonary mass. This can be shown by the lack of mobile bubbles when a subsegmental bronchus is flooded with saline solution. The Black Hole Sign consists in the circular penumbra observed at the end of a bronchus which communicates with a cavity.

Abstract
The occlusion of a postpneumonectomy bronchopleural fistula with a diabolo shaped silicone device inserted through a rigid bronchoscope is reported.
Endobronchial treatment in the airway obstruction – 100 cases

Introduction
Tracheobronchial unclogging is a method to permeabilize the airway and offer a better quality of life for the patient. As of 1997, the bronchoscopy service of the Enrique Tornú Hospital performs the first endo-surgical treatments of the tracheal and bronchial lumen, with the use of stents, occlusive and sub occlusive lesions of benign or malignant nature, trachea and/or bronchi were treated in 100 patients. All of them have been members of the surgery.
Silicone Stent in Tracheobronchial Obstructions: 3 years of experience

Introduction
Tracheobronchial prostheses are utilized to treat obstruction of the great airway in benign conditions and to alleviate the effects of obstruction caused by neoplastic pulmonary disease.
Intervention – Prostheses – Times: 300 cases

Introduction
Endoscopic treatment of lesions that produce occlusion or sub-occlusion of different magnitude in the trachea, source bronchi or in some lobular, has achieved sufficient diffusion within the international medical community to the point where its realization is well established (1). The indication to apply a method that can recover the pulmonary ventilation suspended by the presence of an obstructive lesion appears immediately in the bronchoscopists.
