Delayed endoscopy increases re-bleeding and mortality in patients with hematemesis and active esophageal variceal bleeding: a cohort study.

OBJECTIVE

Active bleeding is a poor prognostic indicator in patients with acute esophageal variceal bleeding. This study aimed at determining indicators of 6-week re-bleeding and mortality in patients with "active" esophageal variceal bleeding, particularly emphasizing the presenting symptoms and timing of endoscopy to define the treatment strategy.

METHODS

From July 2005 to December 2009, cirrhotic patients with endoscopy-proven active esophageal variceal bleeding were evaluated. Cox proportional hazards regression analysis was used to determine the indicators of 6-week re-bleeding and mortality. Outcome comparisons were performed by Kaplan-Meier method and log rank test.

RESULTS

In 101 patients, the overall 6-week and 3-month re-bleeding rates were 25.7% (n=26) and 29.7% (n=30), respectively. The overall 6-week and 3-month mortality was 31.7% (n=32) and 38.6% (n=39), respectively. Door-to-endoscopy time (hr), MELD score, and portal vein thrombosis were indicators of 6-week re-bleeding, while hematemesis upon arrival, MELD score, and hepatocellular carcinoma were indicators of 6-week mortality. Overall mortality was poorer in hematemesis than in non-hematemesis patients (39.7% vs. 10.7%, p=0.007). In hematemesis patients, 6-week re-bleeding rate (18.9% vs. 38.9%, p=0.028) and mortality (27% vs. 52.8%, p=0.031) were lower in those with early (≤ 12 h) than delayed (>12h) endoscopy. In non-hematemesis patients, early and delayed endoscopy had no difference on 6-week re-bleeding rate (17.6% vs. 18.2%, p=0.944) and mortality (11.8% vs. 9.1%, p=0.861).

CONCLUSIONS

It is likely that early endoscopy (≤ 12 h) is associated with a better outcome in hematemesis patients, but a randomized trial with larger case numbers is required before making a firm conclusion.
