Scoping within six hours did not beat early endoscopy in non-variceal upper GI bleeding

Design

Systematic review and random-effects meta-analysis of comparative studies (nine studies)

Population

10,785 adults with non-variceal upper gastrointestinal bleeding (2,638 ultra-early, 8,147 early)

Primary outcome

Mortality and rebleeding with endoscopy within 6 hours vs later

Effect

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

This meta-analysis compared ultra-early endoscopy (within 6 hours of presentation, admission or diagnosis) with endoscopy later within the usual window in adults with non-variceal upper gastrointestinal bleeding. Nine studies with 10,785 patients were included: 2,638 ultra-early and 8,147 early. High-risk patients were defined mostly by a Glasgow-Blatchford score above 12 or a Rockall score above 5.

Ultra-early endoscopy did not significantly lower mortality (OR 0.88, 95% CI 0.58 to 1.34) or rebleeding (OR 1.23, 95% CI 0.90 to 1.67), and it did not change transfusion, surgery, repeat endoscopy or length of stay. ICU admission was more frequent in the ultra-early group (OR 1.41, 95% CI 1.20 to 1.66). Results were consistent in high-risk subgroups.

The included studies are described as comparing groups, not as randomised trials, so selection effects (the sickest patients scoped first) may bias both directions. Current guidelines recommend endoscopy within 24 hours, and this analysis does not change that. It supports prioritising resuscitation and a well-prepared scope within the usual window, and prospective studies in high-risk patients are still needed.

• Aim for endoscopy within 24 hours in line with your guideline, after resuscitation.
• Do not delay resuscitation or planning to chase a six-hour scope in a patient who is not yet stable.
• Reserve the earliest slot for patients you judge at highest risk, using your local protocol.
• Plan ICU or high-dependency care for those who are unstable, whatever the scope timing.
• Record the time to endoscopy and outcome so local practice can be audited.

Why it matters

It challenges the idea that faster is always better for endoscopy in a bleeding patient.

Don't overread it

The pooled studies were comparative groups rather than described as randomised trials, and the guideline recommendation of endoscopy within 24 hours has not changed.

The statistics, in plain English

An odds ratio of 0.88 for mortality with an interval from 0.58 to 1.34 means the data cannot distinguish a 42% reduction from a 34% increase. The higher ICU admission rate (OR 1.41) may reflect the sicker patients who were scoped first rather than harm from the timing.
