Modified method for tracheoesophageal fistula closure in intractable cases

Area of Science:

• Otolaryngology
• Surgical Innovation
• Voice Restoration

Background:

• Tracheoesophageal puncture (TEP) is a key method for voice restoration after total laryngectomy.
• Enlarged TE fistulas causing saliva leakage into the trachea are a significant post-TEP complication.
• Effective management of TE fistula enlargement is crucial for patient recovery and quality of life.

Purpose of the Study:

• To introduce and validate a novel surgical strategy for closing enlarged tracheoesophageal (TE) fistulas.
• To assess the safety and efficacy of this new approach in managing refractory TE fistula complications.
• To improve outcomes for patients experiencing persistent saliva leakage after TEP.

Main Methods:

• A tailored surgical approach based on the condition of the tracheal mucosa and esophagotracheal space.
• Specific techniques for skin incision and separation of the trachea and esophagus, including posterior tracheal wall reconstruction with a superior skin flap when necessary.
• Application of the novel method in four patients with complex conditions, including post-radiation and post-reconstruction scenarios.

Main Results:

• Successful closure of TE fistulas in all treated patients, with no instances of postoperative leakage.
• Resumption of oral intake without complications in all cases.
• Demonstrated effectiveness in challenging patient profiles, including those with prior radiotherapy or extensive reconstructive surgery.

Conclusions:

• The developed strategy for TE fistula closure is safe and effective, even in complex and difficult-to-treat cases.
• This condition-based approach offers a reliable solution for managing TE fistula enlargement and associated saliva leakage.
• The findings support the adoption of this novel technique for improving outcomes in post-laryngectomy voice rehabilitation.
