Modified vacuum-assisted closure (EndoVAC) therapy for treatment of pharyngocutaneous fistula: Case series and a review of the literature.

ABSTRACT

BACKGROUND: Pharyngocutaneous fistula is a potential life-threatening complication following head and neck surgery. There is only limited evidence about the efficacy of vacuum-assisted closure (VAC) therapy and endoscopic vacuum-assisted closure (EndoVAC) therapy for the treatment of pharyngocutaneous fistulas. METHODS: In this article, we report on a consecutive case series of six male patients with pharyngocutaneous fistula treated with a modified outside-in EndoVAC technique. We also present a review of the current related literature. RESULTS: EndoVAC therapy alone was successful in five of the six patients (83.3%) with a median duration of EndoVAC therapy of 18.5 days (range 7 to 32 days) and a median number of EndoVAC sponge changes of 4 (range 1 to 9 changes). One patient needed additional reconstructive surgery after prior radiochemotherapy and jejunal transfer. No treatment-related complications were observed. CONCLUSION: EndoVAC therapy is an easy-to-perform, safe procedure for the treatment of pharyngocutaneous fistulae.
