An alternative method for airway management with combined tracheal intubation and rigid bronchoscope.

Ann Thorac Surg 2019 Feb 7. Epub 2019 Feb 7.

Department of Thoracic Surgery, University of Perugia Medical School, Loc. Sant'Andrea delle Fratte, 06134, Perugia, Italy. Electronic address:

An innovative technique for airway management, utilizing a small diameter, short-cuffed, orotracheal tube for assisting rigid bronchoscopy in critical airway obstruction is reported. The device, part of Translaryngeal Tracheostomy KIT, was placed beyond the stenosis and used in combination with the rigid bronchoscope. This procedure improves safety during the management of critical tracheal stenoses, because the airway is constantly under the anesthesiologist's control. Read More

Insertion of a Dumon Y-stent via a permanent tracheostoma without using a rigid bronchoscope.

BMJ Case Rep 2018 Nov 28;11(1). Epub 2018 Nov 28.

Division of General Thoracic Surgery, Department of Surgery, Shiga University of Medical Science, Otsu, Japan.

A 63-year-old man who had received a permanent tracheostoma after oesophageal cancer surgery developed fistulas in the left and right main bronchi and suffered repeated aspiration pneumonia. Placing an indwelling Dumon Y-stent using a rigid bronchoscope is an option to treat fistula and stenosis at the tracheal bifurcation, but in some cases, it may be difficult to use a rigid bronchoscope in patients with a permanent tracheostoma. In this study, we report placing a Dumon Y-stent in a patient with a permanent tracheostoma using a specially modified stent and forceps instead of a rigid bronchoscope. Read More

Predictors of recurrence after surgical treatment of idiopathic progressive subglottic stenosis.

Acta Otorhinolaryngol Ital 2018 Oct;38(5):417-423

Department of Otorhinolaryngology Head and Neck Surgery, Klinikum Stuttgart, Germany.

Idiopathic progressive subglottic stenosis is a rare cause of tracheal narrowing. Partial cricotracheal resection and anastomosis can cure idiopathic stenosis, even if some patients may require multiple interventions and experience voice and swallowing deterioration. We investigated risk factors for retreatment and assessed the impact of crico-tracheal resection on functional parameters. Read More

[Postintubation tracheal stenosis].

Tuberk Toraks 2018 Sep;66(3):239-248

Clinic of Chest Diseases, Istanbul Yedikule Chest Diseases and Thoracic Surgery Training and Research Hospital, Istanbul, Turkey.

Postintubation tracheal stenosis (PITS) is an iatrogenic complication seen increasingly often as the number of intensive care unit (ICU) bed multiply, the indications for endotracheal intubation expand and disease awareness rises. PITS has a clinical severity spectrum ranging from asymptomatic cases to patients requiring urgent interventional procedures. It should therefore always be considered in the differential diagnosis in patients with a history of intubation who present with the complaint of difficult breathing. Read More

An omentum-cultured 3D-printed artificial trachea: in vivo bioreactor.

Artif Cells Nanomed Biotechnol 2018 Nov 19:1-10. Epub 2018 Nov 19.

a Department of Otorhinolaryngology-Head and Neck Surgery, Chuncheon Sacred Heart Hospital, College of Medicine , Hallym University , Chuncheon , Republic of Korea.

The purpose of this study was to evaluate whether the prior implantation of a 3D-printed polycaprolactone (PCL) artificial trachea in the omentum is beneficial for revascularization of the scaffold and reduces associated complications in the reconstruction of a circumferential tracheal defect. Ten New Zealand rabbits were divided into 2 groups: (1) PCL-OC group (PCL scaffold cultured in omentum for 2 weeks before transplantation) and (2) PCL group. In the PCL-OC group, newly formed connective tissue completely covered the luminal surface of the scaffold with mild inflammation at 2 weeks postoperatively; a minor degree of stenosis was noted at 8 weeks postoperatively.

Fluid dynamic assessment of tracheal flow in infants with congenital tracheal stenosis before and after surgery.

Med Biol Eng Comput 2018 Nov 13. Epub 2018 Nov 13.

Graduate School of Engineering Science, Osaka University, 1-3 Machikaneyama, Toyonaka, Osaka, 560-8531, Japan.

Tracheal flow in infants with congenital tracheal stenosis (CTS) was numerically investigated using subject-specific airway models before and after reconstructive surgery. We quantified tracheal flow based on airway resistance during inhalation, and compared it between controls and patients before and after surgery. The airway resistance in each subject was assessed using geometrical parameters of the trachea: the minimum cross-sectional area A, the minimum cross-sectional area normalized by the standard deviation of the cross-sectional area A/σ, the area ratio of the minimum and maximum cross-sectional area A/A, and ratio of the normalized standard deviation of cross-sectional area to the mean cross-sectional area σ/A.
