Abstract

To identify the risk factors associated with rebleeding in obscure gastrointestinal bleeding (OGIB) patients from southern China. This retrospective study involved 229 patients who underwent small bowel endoscopy in our hospital between 1 January 2018 and 1 December 2020. The clinical characteristics and risk factors related to rebleeding were retrospectively evaluated. Rebleeding patients were significantly older than non-rebleeding patients (53.0 ± 15.9 vs. 46.2 ± 17.8 years), had lower hemoglobin concentrations (89.2 ± 28.1 vs. 126.2 ± 25.1 g/L), and higher blood urea nitrogen concentrations (5.4 ± 2.6 vs. 4.5 ± 2.2 µmol/L), respectively. A higher percentage of rebleeding patients had diabetes mellitus (13.9% vs. 2.9%) and overt bleeding (70.4% vs. 38.6%), and required blood transfusions (43.1% vs. 8.0%), compared with non-rebleeding patients, respectively. Multivariate logistic analysis indicated that drinking alcohol (odds ratio (OR): 9.27; 95% confidence interval (CI) = 1.35-63.78), anemia (OR: 17.38; 95% CI = 5.48-55.10), and blood transfusion (OR: 3.76; 95% CI = 1.04-13.56) increased the risk of rebleeding in OGIB patients. Our data suggested that OGIB patients who drink alcohol, have anemia, and require blood transfusion have an increased risk of rebleeding.
