The management of pharyngocutaneous fistulas after total laryngectomy and the factors affecting their incidence

Abstract

OBJECTIVES: This study sought to determine the incidence and etiologic factors of pharyngocutaneous fistulas occurring after total laryngectomy. PATIENTS AND METHODS: A total of 138 patients (136 males, 2 females; mean age 59.5 years; range 36 to 83 years) underwent total laryngectomy for squamous cell carcinoma. Risk factors and the management of pharyngocutaneous fistulas were assessed together with durations in relation to fistula occurrence, oral feeding, hospitalization, and healing. RESULTS: Pharyngocutaneous fistulas were seen in 37 patients (26.8%). Significantly high rates of fistula occurrence were detected in patients with alcohol consumption (p=0.032), and in those who underwent partial pharyngectomy (p=0.058) or bilateral neck dissection (p=0.049) along with total laryngectomy. The occurrence of fistulas was significantly associated with prolonged lengths of time for oral feeding and hospital stay (p<0.001). Fistulas were repaired surgically in 24.3% of patients, in whom the time to oral feeding was significantly shorter than that of patients who received local wound care (p=0.03). CONCLUSION: Our data show that early surgical intervention is more beneficial in preventing further morbidity associated with pharyngocutaneous fistulas.
