Life-Threatening Respiratory Distress in a Total Laryngectomy Patient: Aspirated Voice Prosthesis or Lung Tumor?

Laryngectomy patients usually have poor pulmonary functions due to long-term smoking. Their lungs can easily be decompensated. Hence, meticulous evaluation and timely management of severe respiratory distress in laryngectomy patients can be life savers. Here we present an interesting case of a laryngectomy patient with two different clinical presentations of life-threatening respiratory distress at the same time (aspiration of voice prosthesis and a second primary lung cancer). Marked or persistent respiratory distress in a laryngectomy patient deserves thorough clinical evaluation and may require urgent intervention. We consider that the presentation and course of respiratory distress in our laryngectomy patient will provide an additional aspect for emergency room doctors and airway specialists dealing with such a patient.

[Solving problems after rehabilitation with voice prostheses : Two rare cases of fistula-related complications]

During the past three decades, the use of voice prostheses has developed worldwide into the gold standard for voice rehabilitation after total laryngectomy. Insertion of a voice prosthesis is a simple and rapid surgical procedure, which is associated with a low rate of complications. The current article describes the cases of 2 patients showing a rapid development of granulation tissue around the voice fistula, leading to complete incarceration of the prosthesis and subtotal/total stenosis of the neopharynx.

The development and treatment of periprosthetic leakage after prosthetic voice restoration. A literature review and personal experience part I: the development of periprosthetic leakage

In the past 30 years, the use of a voice prosthesis has become the treatment of choice for the restoration of speech following laryngectomy. Not only is the placement of a voice prosthesis a simple surgical procedure, but it is also associated with a low rate of complications and an excellent success rate. Approximately, 20-30 % of all patients with voice prostheses, however, develop periprosthetic leakage with aspiration over time. Periprosthetic leakage is usually caused by an enlargement of the tracheo-oesophageal fistula and substantially affects the quality of life of the patients concerned. In a retrospective analysis of our patients, the incidence of periprosthetic leakage was 35.7 % in a total of 232 patients who underwent laryngectomy during a period of 20 years. Substantial enlargement of the tracheo-oesophageal fistula which required multiple treatments occurred in 12.5 % of the patients. In this review, the various causes of fistula enlargement are discussed on the basis of the literature and the experience that we have accumulated during the past 20 years in the management of patients with voice prostheses.

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.

'Speaking valve' aspiration in a laryngectomy patient

Tracheo-oesophageal speech using a one-way speaking valve is a common mode of speech rehabilitation for laryngectomy patients. Aspiration of this device can cause significant airway obstruction and pose anaesthetic and surgical challenges during its retrieval. In this case report, we describe our management of a patient who had had a laryngectomy who aspirated his speaking valve through his stoma. Emergency retrieval of the valve was performed, during which difficulties were encountered, first in obtaining an adequate seal for pre-oxygenation, and second in maintaining adequate oxygen saturation. We discuss some innovative techniques that could be used to address these issues.

Prevention of aspiration following recurrent dislodgement of voice prosthesis: a patient's innovation

Objective:

To demonstrate a simple, practical, cheap method of preventing potentially fatal aspiration of a dislodged voice prosthesis; this method was developed by a laryngectomised patient.

Case report:

A patient diagnosed with squamous cell carcinoma of the larynx underwent total laryngectomy. Upon completion of radiotherapy, a tracheoesophageal fistula was created and a voice prosthesis inserted to enable voice restoration. Unfortunately, the patient presented subsequently with repeated episodes of dislodgement and an episode of potentially fatal aspiration of the voice prosthesis, despite various measures taken by the surgeons to overcome the problem. The patient subsequently developed a method enabling him to retrieve the voice prosthesis himself should it become dislodged. He attached a ring to the prosthesis, which was larger in diameter than the tracheal stoma, thus preventing ingestion or recurrence of aspiration.

Conclusion:

To our knowledge, this is the first report in the world literature of this form of innovation, created by a laryngectomised patient, to overcome the problem of aspiration or ingestion of a dislodged voice prosthesis.
