Abstract
Introduction:
Pharyngocutaneous fistula (PCF) is the most common complication following total laryngectomy (TL). The factors contributing to its occurrence are still a matter of debate. The impact of suture type has been relatively underexplored. This study aimed to analyze the risk factors associated with PCF and understand how the type of suture influences PCF characteristics.
Materials and Methods:
An observational study encompassing all TL procedures was performed between 2005 and 2022 at a secondary care hospital. Sociodemographic and clinical variables widely studied in the literature to identify PCF risk factors were considered. Additionally, the characteristics of fistulas were examined to assess the influence of the suture type.
Results:
Seventy TL cases were included. The incidence of PCF was 56.0%. Identified risk factors for PCF included pharyngeal closure type (p=0.001) (RR=13.09), nutritional support type (p=0.001) (RR=13.54), the need for reintervention due to postoperative bleeding (p=0.001) (RR=1.13), and the need for blood transfusion after surgery (p=0.015) (RR=1.20). Regarding the suture type, Modified Connell Suture (MCS) was associated with a later onset of fistula (p=0.014), shorter hospital stay (p=0.001), and early initiation of oral feeding (p=0.009).
Conclusion:
PCF occurrence is associated with nasogastric tube use, Lambert closure, postoperative bleeding, and reintervention for bleeding after TL. Moreover, MCS sutures are linked to a shorter hospital stays and early initiation of oral feeding.
