A Novel Technique of Negative Pressure Wound Therapy for Pharyngeal Cutaneous Fistulas Around Tracheostomas.

Fistula formation after free jejunal transplantation is relatively common; however, treating esophago-jejunal anastomosis fistulas is difficult. Herein, the authors report a case of esophago-jejunal anastomosis fistula adjacent to the permanent tracheostoma after free jejunal transplantation that was closed using negative pressure wound therapy (NPWT). A 70-year-old man underwent total pharyngo-laryngo-cervical esophagectomy and free jejunal transplantation for hypopharyngeal cancer. After reconstruction, an esophago-jejunal anastomosis fistula developed on the permanent tracheostoma margin. The fistula was sutured, but it recurred. Therefore, NPWT was performed to close the fistula via the bridge method and balloon compression using a tracheal cannula. NPWT requires the maintenance of local negative pressure. However, esophago-jejunal anastomosis fistula formation after free jejunal transplantation makes this difficult because of the unevenness of the permanent tracheostoma and moist surface of the tracheal mucosa. NPWT performed using the bridge method and balloon compression is an effective option for fistula treatment.
