RESUMO
BACKGROUND: Pharyngocutaneous fistula is one of the most common complications following total laryngectomy. It increases hospital stay and the financial burden on patients, and prolongs nasogastric feeding. This paper presents novel techniques for prevention of pharyngocutaneous fistula. METHOD: A retrospective study was conducted at a tertiary referral centre to assess the effectiveness of continuous extramucosal pharyngeal suturing and the hydrogen peroxide leak test in prevention of pharyngocutaneous fistula in 59 patients who had undergone total laryngectomy with or without partial pharyngectomy for locally advanced cancers of the larynx and hypopharynx. RESULTS: The incidence of pharyngocutaneous fistula in our study was 6.8 per cent, which is considerably lower than the incidence reported in various previous studies. CONCLUSION: The continuous extramucosal suturing technique provides watertight closure of the neopharynx and can be recommended as a reliable method for neopharyngeal closure post total laryngectomy to reduce the occurrence of pharyngocutaneous fistula.
