Background: Current guidelines recommend endoscopic therapy to be performed within 12 h for acute variceal bleeding (AVB). However, the optimal timing of endoscopic therapy for AVB remains unclear., Aims: To examine the relationship between the endoscopy timing and clinical outcomes in AVB, with emphasis on liver function and endoscopy timing., Methods: From January 2010 to June 2017, cirrhotic patients with AVB confirmed by endoscopy were evaluated. The primary outcome was a composite of 6-week rebleeding and mortality. We stratified patients according to the MELD score., Results: In 411 patients, the overall composite outcome rate was 30.9% (n = 127) at 6 week. Patients who underwent urgent endoscopy (≤12 h) had a significantly higher composite outcome than patients who underwent non-urgent endoscopy (>12 h) (34.4% vs. 19.1%; P = 0.005). Low-risk patients who underwent urgent endoscopy were more likely to reach the composite outcome (adjusted OR, 0.84 per 4 h; 95% CI, 0.73-0.98; P = 0.027). These findings persisted even after adjustment for baseline characteristics between the urgent and non-urgent groups., Conclusions: Urgent endoscopy is significantly associated with a poorer outcome in patients with AVB, especially in low-risk patients. Our result provides a treatment strategy according to the severity of underlying liver disease in patients with AVB., (Copyright © 2019 Editrice Gastroenterologica Italiana S.r.l.
