Abstract

Abstract: Prophylactic arterial ligation has been proposed to reduce the severity of postoperative hemorrhage following transoral robotic surgery (TORS). Previous studies have shown a trend toward a reduction in major and severe bleeding. Search strategies were implemented in multiple databases and completed in August 2018. Inclusion and exclusion criteria were designed to capture studies examining adults undergoing TORS for oropharyngeal cancer. Four retrospective studies were selected appropriate for analysis by two reviewers who independently extracted data. PRISMA guidelines were followed. A random‐effects model was used for meta‐analysis. Meta‐analysis of 619 patients in four retrospective reviews showed that the pooled RR of major and severe bleeding events was significantly lower in prophylactically ligated patients (RR, 0.28; 95% CI, 0.08‐0.92; I 2 = 0). Prophylactic arterial ligation of external carotid artery branches is associated with a decreased risk of major and severe bleeding events, although confounding factors remain incompletely analyzed.
