Meta Analysis
Optimal endoscopy timing in patients with acute variceal bleeding: A systematic review and meta-analysis.
Although current guidelines recommend performing endoscopy within 12 hours for acute variceal bleeding (AVB), the optimal timing remains controversial. This study aimed to assess the effect of endoscopy timing on the mortality and rebleeding rates in AVB through a systematic review and meta-analysis of all eligible studies. PubMed, Cochrane Library, and Embase were searched for relevant publications up to January 2019. ⋯ Other outcomes such as successful haemostasis, need for salvage therapy, length of hospital stay, and number of blood transfusions were also similar between the groups. We demonstrated that endoscopy timing does not affect the mortality or rebleeding rate of patients with AVB. Therefore, an appropriate timing of endoscopy would be more important than an urgent endoscopy depending on each patient's condition.
