Injection of porcine dermal collagen paste for leaking tracheoesophageal speech fistula

Voice rehabilitation following laryngectomy often utilizes speech valves, where a valve is placed in a surgically created tracheoesophageal fistula. The most significant complication of this procedure being leakage around the speaking tube through a widened puncture site. Ultimately, surgical closure of a problematic fistula may be required, and three-layer closure techniques are the most widely recognized. We would like to report a novel technique of injection repair of a leaking fistula using a porcine dermal collagen paste. This injection technique prevents leakage by bulking the tissue surrounding the valve and thus narrowing or tightening the fistula.
