Relationship between platelet-to-lymphocyte ratio and early rebleeding after endoscopic variceal ligation: a bicenter retrospective study.

ABSTRACT

BACKGROUND: Endoscopic variceal ligation (EVL) is the primary treatment for esophageal variceal bleeding in patients with liver cirrhosis (LC). Postoperative rebleeding is a complication of EVL, contributing to over 20% of bleeding-related deaths. This study aims to examine the association between platelet-to-lymphocyte ratio (PLR) and rebleeding within 6 weeks after EVL in patients with LC. METHODS: The study included 145 eligible patients who underwent their first EVL procedure at Yijishan Hospital of Wannan Medical College between January 2016 and August 2022 (YJS cohort). An external validation cohort comprising 338 eligible patients from NO.2 People's Hospital of Fuyang City (FY cohort) between July 2018 and August 2022 was also utilized. RESULTS: In the YJS cohort, Multivariate logistic analysis indicated that high PLR is independently associated with early rebleeding after EVL. The restricted cubic spline analysis demonstrated that the risk of rebleeding increases with rising PLR, stabilizing at PLR values greater than 150. Similar findings were validated in the FY cohort. CONCLUSIONS: Our results have the potential to aid in the identification of high-risk patients for early rebleeding after EVL, thereby enabling improved clinical management and outcomes for these individuals.

This study is the first to report on the independent association between the platelet-to-lymphocyte ratio (PLR) and early rebleeding after endoscopic variceal ligation (EVL).The restricted cubic spline analysis showed a linear correlation between PLR and the risk of early rebleeding after EVL.An increase in PLR level is independently associated with a higher risk of early rebleeding after EVL.
