Outcomes and Role of Urgent Endoscopy in High-Risk Patients With Acute Nonvariceal Gastrointestinal Bleeding

BACKGROUND & AIMS: We investigated clinical outcomes in high-risk patients with acute nonvariceal upper gastrointestinal bleeding (UGIB), and determined if urgent endoscopy is effective. METHODS: Consecutive patients with a Glasgow-Blatchford score greater than 7 who underwent endoscopy for acute nonvariceal UGIB at the emergency department from January 1, 2005, to December 31, 2014, were included. Urgent (<6 h) and elective (6-48 h) endoscopies were defined according to the time to endoscopy after the initial presentation. The primary outcomes were mortality and rebleeding within 28 days of admission. RESULTS: Among 961 patients, 571 patients underwent urgent endoscopy. The 28-day mortality rate was 2.5%, and the rebleeding rate was 10.4%. There were significant differences in mortality rate (1.6% vs 3.8%), the number of transfused packed red blood cells (2.6 +/- 2.5 vs 2.3 +/- 2.1 packs), need for intervention (69.5% vs 53.5%), and embolization (2.8% vs 0.5%), but no differences in rebleeding, intensive care unit admission, vasopressor use, and length of stay between the urgent and elective endoscopy groups. Mortality was associated with malignancy (odds ratio [OR], 3.58; 95% confidence interval [CI], 1.33-9.62), cirrhosis (OR, 4.67; 95% CI, 1.85-11.76), urgent endoscopy (OR, 0.36; 95% CI, 0.14-0.95), failed primary endoscopic treatment (OR, 15.03; 95% CI, 4.63-48.82), and rebleeding (OR, 2.77; 95% CI, 1.03-7.45). Rebleeding was associated with Forrest I ulcers (OR, 7.67; 95% CI, 2.71-21.69), Forrest II ulcers (OR, 2.34; 95% CI, 1.51-3.60), and coagulopathy (OR, 2.34; 95% CI, 1.51-3.60). CONCLUSIONS: Urgent endoscopy was an independent predictor of lower mortality rate but was not associated with rebleeding in high-risk patients with acute nonvariceal UGIB.
