Ultra-early endoscopy did not reduce death or rebleeding in non-variceal upper GI bleeding

Design

Systematic review and random-effects meta-analysis

Population

9 studies, 10,785 adults with non-variceal upper GI bleeding

Primary outcome

Mortality and rebleeding, endoscopy ≤6 h vs >6 h

Effect

Mortality OR 0.88 (95% CI 0.58–1.34); rebleeding OR 1.23 (0.90–1.67); ICU admission OR 1.41 (1.20–1.66)

This meta-analysis pooled nine studies of 10,785 adults with non-variceal upper gastrointestinal bleeding, comparing endoscopy within 6 hours of presentation (2,638) with later endoscopy (8,147), which in most studies meant within 24 hours.

Ultra-early endoscopy did not reduce mortality (OR 0.88, 95% CI 0.58 to 1.34) or rebleeding (OR 1.23, 0.90 to 1.67), and did not change transfusion, surgery, repeat endoscopy or length of stay. ICU admission was more frequent (OR 1.41, 1.20 to 1.66). Results were the same in high-risk patients, mostly defined by a Glasgow-Blatchford score above 12.

This matches a large randomised trial that found no benefit from endoscopy within 6 hours in high-risk patients. Out-of-hours emergency endoscopy puts pressure on teams and may be done before adequate resuscitation. The evidence supports resuscitating first and scoping within 24 hours.

• Aim for endoscopy within 24 hours in non-variceal upper GI bleeding; within 6 hours has not been shown to help.
• Resuscitate first: fluids, blood if needed, and correct coagulopathy where appropriate, without delaying endoscopy.
• A Glasgow-Blatchford score above 12 alone does not justify a middle-of-the-night scope in a stable patient.
• Haemodynamic instability despite resuscitation still needs urgent endoscopy or intervention.
• Variceal bleeding follows a different pathway with its own timing targets.

Why it matters

It removes the pressure for emergency out-of-hours endoscopy in stable patients, freeing teams to resuscitate properly first.

Don't overread it

Most included studies were observational; unstable patients who do not respond to resuscitation still need urgent endoscopy.

The statistics, in plain English

Both mortality and rebleeding odds ratios have confidence intervals crossing 1.0, so no benefit is shown. The higher ICU admission (OR 1.41) may reflect sicker patients being scoped early rather than harm from early endoscopy, since most included studies were observational.
