A pharyngocutaneous fistula (PCF) is the most common complication after salvage total laryngectomy (STL) with an incidence ranging from 5 to 73%, causing an increase in morbidity and delaying the patient’s recovery. A surgical technique to prevent PCF formation is the use of the stapler to suture the pharyngeal mucosa. We have reviewed the medical files of 91 patients who had undergone STL, dividing the patients into two groups (manual suture vs. stapler), based on the type of pharyngeal suture performed during the STL. We found 12/49 (24.5%) cases of a PCF in group A (manual) and 5/42 (11.9%) cases of a PCF in group B (stapler). There is a statistically significant difference between the two groups with the patients in group B presenting better results in terms of the reduction of the surgical time, the length of the hospital stay and also in the restarting of oral feeding. The advantages of mechanical suturing with the stapler are reduced surgical times, a lower PCF formation rate, which involves an early removal of the nasogastric tube, and reduced hospitalization times. Further studies with a larger case series will be necessary to confirm the results obtained and to standardize the surgical technique.

Abstract
A pharyngocutaneous fistula (PCF) is the most common complication after salvage total laryngectomy (STL) with an incidence ranging from 5 to 73%, causing an increase in morbidity and delaying the patient’s recovery. A surgical technique to prevent PCF formation is the use of the stapler to suture the pharyngeal mucosa. We have reviewed the medical files of 91 patients who had undergone STL, dividing the patients into two groups (manual suture vs. stapler), based on the type of pharyngeal suture performed during the STL. We found 12/49 (24.5%) cases of a PCF in group A (manual) and 5/42 (11.9%) cases of a PCF in group B (stapler). There is a statistically significant difference between the two groups with the patients in group B presenting better results in terms of the reduction of the surgical time, the length of the hospital stay and also in the restarting of oral feeding. The advantages of mechanical suturing with the stapler are reduced surgical times, a lower PCF formation rate, which involves an early removal of the nasogastric tube, and reduced hospitalization times. Further studies with a larger case series will be necessary to confirm the results obtained and to standardize the surgical technique.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
