Clinical Feasibility of New Tracheoesophageal Puncture Set

This study has been completed.
Information provided by (Responsible Party):
Atos Medical AB Identifier:
First received: January 6, 2010
Last updated: February 10, 2015
Last verified: February 2015
During a total laryngectomy a puncture is created in the tracheoesophageal wall and a voice prosthesis is inserted. With this voice prosthesis the patient learns to speak again. During this study a new surgical tool will be investigated that creates the puncture and places the voice prosthesis.

Condition Intervention Phase
Larynx Cancer Device: Puncture Set and Flexible Protector Phase 1 Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Clinical Feasibility of a New Surgical Tool for Primary or Secondary Tracheoesophageal Puncture and Voice Prosthesis Insertion for Prosthetic Voice Rehabilitation After Total Laryngectomy

Further study details as provided by Atos Medical AB:

Primary Outcome Measures:
  • Success Rate of Procedure [ Time Frame: immediate observation during surgery ]
    As successful counted all successful procedures in which the tracheal flange of the voice prosthesis unfolded completely without help of additional tools. A success rate of 80% and higher was considered acceptable.

Secondary Outcome Measures:
  • Satisfaction of Physician [ Time Frame: 1 month ]
    Satisfaction of the physicians with the new tools was investigated by asking them which tool set they prefer: the new set from the study or the set they would have normally used.

  • Cost Effectiveness Calculation [ Time Frame: 1 month ]

    cost effectiveness of the new tool set is compared to that of the set that would have been used in the absence of the new puncture set.

    Measurements are: time needed to perform procedure

  • Postoperative Results [ Time Frame: 1 month ]
    Patients were followed-up one month after surgery.Patients with secondary punctures filled out a questionnaire.

Enrollment: 27
Study Start Date: December 2009
Study Completion Date: April 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Puncture Set and Flexible Protector
Provox Vega Puncture Set is used to create the primary puncture and insert the prosthesis during total laryngectomy
Device: Puncture Set and Flexible Protector
The Provox Vega Puncture Set will be used to create the tracheoesophageal puncture and place the voice prosthesis. In secondary punctures the Provox Flexible Protector may be used for pharynx protection.

Inclusion Criteria:

  • primary puncture during total laryngectomy
  • secondary puncture some time after total laryngectomy

Exclusion Criteria:

  • anatomical abnormalities that prevent appropriate pharynx protection during secondary puncture
