Does early oral feeding increase the likelihood of salivary fistula after total laryngectomy?

Abstract

Abstract Objective: This study compared the incidence of salivary fistula between groups with an early or late reintroduction of oral feeding, and identified the predictive factors for salivary fistula. Methods: A randomised trial was performed using 89 patients with larynx or hypopharynx cancer, assigned to 2 groups (early or late). In the early group, oral feeding was started 24 hours after total laryngectomy or total pharyngolaryngectomy, and in the late group, it was started from post-operative day 7 onwards. The occurrence of salivary fistula was evaluated in relation to the following variables: early or late oral feeding, nutritional status, cancer stage, surgery performed, and type of neck dissection. Results: The incidence of salivary fistula was 27.3 per cent ( n = 12) in the early group and 13.3 per cent ( n = 6) in the late group ( p = 0.10). The following variables were not statistically significant: nutritional status ( p = 0.45); tumour location ( p = 0.37); type of surgery ( p = 0.91) and type of neck dissection ( p = 0.62). A significant difference ( p = 0.02) between the free margins and invasive carcinoma was observed. Conclusion: The early reintroduction of oral feeding in total laryngectomised patients did not increase the incidence of salivary fistula.
