Trial summary

The tracheoesophageal voice with voice prosthesis is currently the mainstay of voice rehabilitation post laryngectomy. The primary surgical technique of tracheoesophageal fistula formation with insertion of prosthesis and quick and easy process of voice rehabilitation are main encouraging factors.

About this study

Official title: Estimation of Benefit From Regular Versus Leakage-related Exchange of Voice Prosthesis in Patients Post Laryngectomy Considering Complications Rate, Fistula Colonization by Candida Species and Patients Satisfaction Feedback.

The tracheoesophageal voice with voice prosthesis is currently the mainstay of voice rehabilitation post laryngectomy. The primary surgical technique of tracheoesophageal fistula formation with insertion of prosthesis and quick and easy process of voice rehabilitation are main encouraging factors. However, the usage of the prosthesis relates to a significant number of complications rated from 10 to 60%. The most common reported complication is transprosthetic leakage that determines the need of device exchange. However in some patients occur more serious complications eg. periprosthetic leakage, granulation or atrophy of mucosa around the fistula, dislocation of prosthesis, that may require anti-inflammatory treatment, temporary nasogastric tube feeding or surgical procedure. The standard protocol is voice prosthesis exchange due to transprosthetic leakage. Optionally the device could be replaced regularly to prevent both transprosthetic leakage and other complication occurrence.

In the study we plan to compare the benefits from regular (each three month) versus leakage-related exchange of voice prosthesis post laryngectomy including the rate of complications, fistula colonization by Candida species and patients feedback.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Provox prosthesis exchangeDevice

    Each patient post laryngectomy will be randomly assigned to one arm of intervention. The voice prosthesis exchange in all patients will be performed in local anaesthesia. The microbiological samples with cotton swabs will be collected from tracheoesophageal fistula on prosthesis exchange. The clinical evaluation and patients satisfaction from prosthesis usage will be performed on each exchange.

Study groupRoleWhat they receive
Regular exchangeActive comparatorPatients will be appointed each 3 months for regular exchange of voice prosthesis.
Receives: Device: Provox prosthesis exchange
Leakage exchangeActive comparatorPatients will have voice prosthesis exchange when leakage occurs.
Receives: Device: Provox prosthesis exchange

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of complications rate.

    In both arms of the study we will compare the incidence of following complications: periprosthetic leakage, granulation or atrophy of mucosa around the fistula, dislocation of prosthesis

    Measured: Control will be continued for 12 months post laryngectomy.

Secondary outcomes (2)
  1. Fistula colonization with Candida species.

    We will compare microbiological results on subsequent prosthesis exchanges in both arms.

    Measured: Control will be continued for 12 months post laryngectomy.

  2. Prosthesis replacement scheme and patient satisfaction.

    On each voice prosthesis exchange patients will be asked three questions, assessed with Visual Analog Scale, on their feedback on voice prosthesis use, procedure of prosthesis replacement and voice quality.

    Measured: Control will be continued for 12 months post laryngectomy.

Questions about this trial

What is this clinical trial studying?

A study testing Provox prosthesis exchange in people with Laryngectomy and Voice, run by Medical University of Warsaw at 1 site in Poland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 13 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Anna Rzepakowska, PhD (+48225992521, arzepakowska@wum.edu.pl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Comparison of complications rate. (time frame: Control will be continued for 12 months post laryngectomy.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04268459, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2020.
