Abstract

Objectives/hypothesis: To analyze stapler benefits in salvage total laryngectomy in terms of surgical time, hospitalization length, oral feeding time, and occurrence of pharyngocutaneous fistula, and to evaluate risk factors for its onset.

Study design: Retrospective analysis.

Methods: One hundred fourteen patients affected by endolaryngeal squamous cell carcinoma who underwent salvage total laryngectomy following primary treatment failure were reviewed. We divided patients into two groups based on type of pharyngeal suture performed: mechanical suture with stapler (group A) and manual suture (group B). These two groups were compared for surgical time, start of oral feeding, hospitalization length, surgical margins and pharyngocutaneous fistula incidence considering its relationship with diabetes mellitus, nutritional status, primary treatment, and neck dissection.

Results: In group A and group B, oral feeding restarting time was 15 ± 9.33 versus 20.03 ± 13.81 days, hospitalization was 17.63 ± 10.08 versus 23.72 ± 14.29 days, and surgery lasted 268.39 ± 76.93 versus 294.26 ± 140.58 minutes, respectively (P < .05). Surgical margins resulted infiltrated in two patients (4.3%) in group A and 12 patients in group B (17.6%) (P = .03). Twenty-one patients (18.4%) presented with pharyngocutanoeus fistula. In group A and group B the incidence of fistula was 15.2% and 20.6%, respectively (P = .468). Fistula occurred in 7 of 18 diabetic patients (38.9%) and 14 of 96 (14.6%) nondiabetic patients (P = .015). Nineteen fistulas (90.5%) occurred in patients who had undergone previous radiation treatment (P = .013).

Conclusions: Using a stapler shortened operative time and hospitalization, while also providing a faster restart of oral feeding. Moreover, mechanical pharyngeal suture seems to decrease fistula rate even though its prevention role in salvage laryngectomy should be confirmed by further studies.
