Urgent Endoscopy in Nonvariceal Upper Gastrointestinal Hemorrhage: A Retrospective Analysis.

OBJECTIVE: The role of urgent endoscopy in nonvariceal upper gastrointestinal hemorrhage (NVUGIH) remains controversial. We designed a retrospective study to compare the outcomes between urgent endoscopy (within 12 h) and non-urgent endoscopy for patients with NVUGIH. METHODS: A total of 540 hospitalized patients with NVUGIH were included in our study. Patients who received endoscopy within 12 h or after 12 h were divided into two groups, the urgent and non-urgent endoscopy groups, respectively. The clinical outcomes including rebleeding, mortality, endoscopic re-intervention, need for emergency surgery and interventional radiotherapy were compared between the groups. Patients with Glasgow-Blatchford scores (GBS) <12 and ≥12 were defined as the lower- and high-risk groups, respectively, and the predictors of rebleeding and mortality in both groups were analyzed individually. RESULTS: Patients with NVUGIH in the urgent endoscopy group had a higher rate of rebleeding (27.6% vs. 16.9%, P=0.003) and blood transfusion (73.2% vs. 55.5%, P<0.001) than those in the non-urgent endoscopy group, while the mortality and the length of hospitalization were not significantly different between the groups (P>0.05). For lower-risk patients, urgent endoscopy was independently associated with a higher likelihood of rebleeding (adjusted OR: 1.73, 95% CI: 1.03-2.88), while it was not associated with in-hospital mortality. However, the urgent need for endoscopy was not associated with rebleeding and inhospital mortality in high-risk patients. CONCLUSION: Endoscopy within 12 h did not provide any advantage in the outcomes of patients with NVUGIH, and may even lead to an increased rebleeding rate in lower-risk patients.
