Timing of Endoscopy for Acute Upper Gastrointestinal Bleeding

Area of Science:

• Gastroenterology
• Clinical Medicine
• Medical Research

Background:

• Standard practice recommends upper gastrointestinal endoscopy within 24 hours for acute bleeding.
• The benefits of performing endoscopy in shorter timeframes (less than 24 hours) remain unclear.
• High-risk patients with acute upper gastrointestinal bleeding require defined optimal timing for endoscopic intervention.

Purpose of the Study:

• To determine if urgent endoscopy (within 6 hours) improves outcomes in high-risk patients with acute upper gastrointestinal bleeding.
• To compare 30-day mortality rates between urgent and early endoscopy groups.
• To assess the impact of endoscopy timing on further bleeding events.

Main Methods:

• A randomized controlled trial involving 516 patients with acute upper gastrointestinal bleeding and a Glasgow-Blatchford score of 12 or higher.
• Patients were assigned to either an urgent-endoscopy group (within 6 hours) or an early-endoscopy group (6-24 hours).
• The primary endpoint was all-cause mortality within 30 days.

Main Results:

• 30-day mortality was 8.9% in the urgent group versus 6.6% in the early group (difference 2.3%; 95% CI, -2.3 to 6.9).
• Further bleeding occurred in 10.9% of the urgent group and 7.8% of the early group (difference 3.1%; 95% CI, -1.9 to 8.1).
• Active bleeding or visible vessels were more frequently found in the urgent group (66.4% vs. 47.8%).

Conclusions:

• Endoscopy within 6 hours was not associated with reduced 30-day mortality in high-risk acute upper gastrointestinal bleeding patients compared to endoscopy within 24 hours.
• The findings suggest that the current 24-hour recommendation is adequate for high-risk patients.
• Further research may explore other factors influencing outcomes in acute gastrointestinal bleeding.
