Does Usage of Salivary Bypass Tube Could Reduce the Risk for Pharyngocutaneous Fistula in Laryngopharyngectomy? A Systematic Review and Meta-Analysis

To evaluate the effect of salivary bypass tube (SBT) usage on the occurrence of pharyngocutaneous fistula (PCF) in patients after a laryngopharyngectomy, a total of 20 studies, published between 1988 and 2021, were identified including 2946 patients. We performed a meta-analysis assessing the risk of PCF occurrence in patients after SBT application compared to those without. PCF occurred in 26.8% of cases (669/2496) and SBT was applied in 33.0% of patients (820/2483). There was an overall trend towards lower PCF rates when using SBTs (22.2% vs. 35.3% ; p = 0.057). We further selected five studies, comprising 580 patients who underwent laryngopharyngectomies, for meta-analysis showing that application of SBT reduced the risk of PCF formation (OR 0.46 ; 95% CI 0.18-1.18 ; p = 0.11). The meta-analysis demonstrates a beneficial effect of SBT insertion on PCF formation in patients after laryngopharyngectomy.
