Core Tip

Core Tip: Rebleeding remains a significant concern in patients with non-variceal upper gastrointestinal bleeding (NVUGIB), despite the improvements in endoscopic and pharmacologic treatments. Our systematic review and meta-analysis indicate that prophylactic transcatheter arterial embolization (PTAE) compared to standard of care is accompanied by lower odds of rebleeding, need for rescue surgery, and reinterventions NVUGIB. However, we could not justify a beneficial effect of PTAE on mortality rates compared with the standard of care. In line with our results, we suggest using PTAE in selected cases, where risk stratification predicts high rebleeding risk or the anatomical situation makes the secure and permanent endoscopic hemostasis impossible.
