Three-layer technique to close a persistent tracheo-oesophageal fistula

Lee LM, Razi A

Asian J Surg, 2004 Oct;27(4):336-8.

PMID: 15564191

This report of a patient with a persistent tracheo-oesophageal (TE) fistula after removal of a speech valve describes a modification of the technique described by Rosen et al for closing TE. Under local anaesthesia, an incision was made above the stoma edge from 9 o'clock to 3 o'clock. The trachea was separated from the oesophagus to beyond the fistula, and the fistula tract was excised. The oesophageal opening was closed in layers and a local flap rotated from the adjacent sternocleidomastoid muscle and sutured over the oesophageal closure. The trachea was then closed separately.

Tissue engineering trachea: Malaysian experience

Aminuddin BS

Med J Malaysia, 2004 May;59 Suppl B:3-4.

PMID: 15468790

Management of severe tracheal anomalies remains a clinical challenge. Tissue engineering offers new hope in trachea reconstruction surgery. However to date no optimal technique achieved in the formation of human or animal trachea. The main problem lies on the biomaterial used and the complex city of forming trachea in vivo. This study was aimed at creating tissue-engineered trachea cartilage from easily accessible human and animal nasal septum cartilage using internal scaffold and biodegradable human and animal fibrin.

Fulltext Tracheobronchial stenting is safe and effective in relieving upper airway obstruction

Pang YK, Liam CK, Leow CH, Shyamala P, Zal AR

Med J Malaysia, 2006 Jun;61(2):147-50.

PMID: 16898303 MyJurnal

Many studies have shown that tracheobronchial stenting is effective in relieving respiratory distress secondary to major airway obstruction due to lung or oesophageal cancer. A retrospective review on the benefits and complications of self-expandable metallic stent (SEMS) insertion through flexible bronchoscopy for the palliative treatment of upper airway obstruction in University Malaya Medical Centre was performed. Ten patients underwent this procedure. Relief of dyspnoea was immediate following stent insertion in all patients. Stent migration occurred in one patient and three patients had restenosis of the central airway. We conclude that tracheobronchial stenting via flexible bronchoscopy is feasible and safe.

Sequelae of traumatic laryngotracheal separation: the need for individualized long term treatment plan

Mazita A, Sani A

Auris Nasus Larynx, 2005 Dec;32(4):421-5.

Laryngotracheal separation is a rare variant of laryngeal trauma. However it is life threatening and potentially fatal. Patients with this injury usually succumb at the site of the accident itself. Here we present two cases of laryngotracheal separation of different etiology and of different outcomes. The treatment advocated for laryngotracheal separation is initially airway stabilization followed by formal repair of the transected trachea. However both our cases illustrates that the outcomes can be different and that a long term treatment plan should be individualized to each patient.

Major tracheobronchial injuries: Management of two rare cases

Huei TJ, Lip HTC, Rahmat O

Med J Malaysia, 2018 06;73(3):177-179.

PMID: 29962504 MyJurnal

Tracheobronchial injuries are uncommon and a high level of suspicion is needed for immediate diagnosis and prompt treatment. In this case series, two rare cases of tracheobronchial injuries is described showing variable clinical presentations with different levels of injury. Our first case was seen in a 20 years old male whom had a direct impact on the neck and presented with upper tracheal injury. On arrival, this patient was in respiratory distress and had bilateral pneumothorax. Bilateral chest tube was inserted with subsequent neck exploration. During the neck exploration, anastomosis of the injured trachea was performed. The second case was represented by a 35 years old man with right main bronchial injury. Upon initial presentation, this patient appeared well and was comfortable under room air. However he gradually deteriorated one week after the trauma requiring surgical intervention. Eventually a thoracotomy with primary anastomosis of the bronchial tear was performed. Details of both cases including clinical presentation, imaging and procedures done will be discussed in this article.

Tracheal tears are not as uncommon as initially thought. The resultant insufficiency and hypoxia can be life-threatening. The keystone in management is early recognition and diagnosis. Immediate surgical repair is essential.

Treatment and management of congenital as well as post-traumatic trachea stenosis remains a challenge in pediatric surgery. The aim of this study was to reconstruct a trachea with human nasal septum chondrocytes by using the combination of biodegradable hydrogel and non-biodegradable high-density polyethylene (HDP) as the internal predetermined shape scaffold.

Complications following tracheoesophageal puncture: a tertiary hospital experience

INTRODUCTION: In laryngectomised patients, tracheoesophageal speech is the gold standard for voice rehabilitation. This study evaluated complications related to the tracheoesophageal puncture (TEP) and the success rate in voice prosthesis after total laryngectomy at our institution over a 10-year period.

MATERIALS AND METHODS: A retrospective review of 22 TEPs was performed between January 1998 and December 2008. The timing of TEP, type of voice prosthesis, surgical and prosthesis-related complications, and TEP closure were noted.

RESULTS: Eighteen percent of the patients underwent primary and 82% secondary TEP. Our patients were predominantly males (95.4%) of Chinese descent with a mean age of 62.1 years. The types of voice prostheses used were ProvoxTM (n = 15), Voicemasters (n = 6), and Blom-Singer (n = 1). Prosthesis- related complications occurred in 77.3%. Notable complications were leakage (82.5%), prosthesis displacement (41.2%), intractable aspiration (29.4%), and aspiration of prosthesis (23.5%). The most common surgical-related complication was tracheostomal stenosis. An array of interventions comprising resizing or changing prosthesis type, nasogastric catheter insertion, stomaplasty, purse string suturing, and bronchoscopic removal of bronchial aspirated prosthesis were implemented to address encountered complications. In a mean follow-up of 34.8 months, 68.2% of patients achieved functional tracheoesophageal speech (75% of primary TEP and 67% of secondary TEP). There were 7 TEP closures indicated by persistent leakage, recurrent dislodgement, phonatory failure and, in 1 patient, persistent pain.

CONCLUSIONS: TEP has become an integral part in the rehabilitation of a laryngectomee. However, management of the frequent complications related to TEP requires specific efforts and specialistic commitments in order to treat them.

Autologous implantation of bilayered tissue-engineered respiratory epithelium for tracheal mucosal regenesis in a sheep model

The objective of this study was to regenerate the tracheal epithelium using autologous nasal respiratory epithelial cells in a sheep model. Respiratory epithelium and fibroblast cells were harvested from nasal turbinates and cultured for 1 week. After confluence, respiratory epithelium and fibroblast cells were suspended in autologous fibrin polymerized separately to form a tissue-engineered respiratory epithelial construct (TEREC). A 3 × 2 cm² tracheal mucosal defect was created, and implanted with TEREC and titanium mesh as a temporary scaffold. The control groups were divided into 2 groups: polymerized autologous fibrin devoid of cells (group 1), and no construct implanted (group 2). All sheep were euthanized at 4 weeks of implantation. Gross observation of the trachea showed minimal luminal stenosis formation in the experimental group compared to the control groups. Macroscopic evaluation revealed significant mucosal fibrosis in control group 1 (71.8%) as compared to the experimental group (7%). Hematoxylin and eosin staining revealed the presence of minimal overgrowth of fibrous connective tissue covered by respiratory epithelium. A positive red fluorescence staining of PKH26 on engineered tissue 4 weeks after implantation confirmed the presence of cultured nasal respiratory epithelial cells intercalated with native tracheal epithelial cells. Scanning electron microscopy showed the presence of short microvilli representing immature cilia on the surface of the epithelium. Our study showed that TEREC was a good replacement for a tracheal mucosal defect and was able to promote natural regenesis of the tracheal epithelium with minimal fibrosis. This study highlighted a new technique in the treatment of tracheal stenosis.
