Postlaryngectomy pharyngocutaneous fistula: Incidence, predisposing factors, and therapy

Abstract

The results observed in the group of patients under analysis corroborated the relevance of factors such as the extension of laryngectomy and postoperative hemoglobin level on fistula occurrence. However, chronic congestive heart failure, which is an expression of disturbance of the organism, emerged for the first time as an additional statistically significant risk factor for pharyngocutaneous fistula formation. Our experience confirmed that most fistulas can be successfully managed with conservative treatment. Except for the rare cases in which large defects are present, direct suture is appropriate when conservative treatment has failed.
