Objective: Anemia is a common problem in outpatient clinics, and endoscopic interventions are one of the initial steps to rule out the gastrointestinal causes. In this study, we aimed to analyze the diagnostic yield of endoscopic interventions in children with severe anemia.
Materials and Methods: The demographic features, laboratory findings, and endoscopic and histopathological findings of 65 children with severe anemia (hemoglobin <7 g/dL) (mean age of 12.1 ± 4.4 years, 73.8% female) who underwent endoscopic interventions were recorded from the files. Patients were divided into 2 groups according to the presence of positive endoscopic findings and/or histopathological examination. Factors that may predict the presence of positive endoscopic findings and/or histopathological examination were analyzed.
Results: After a colonoscopy and/or upper gastrointestinal endoscopy, the etiology of anemia was identified in 35 patients, and the major diagnosis of Helicobacter pylori gastritis in 16.9% and gastrointestinal ulcer in 10.8% of the patients was made. No gastrointestinal pathology was detected in 30 patients. The diagnostic yield of endoscopic examination in patients with severe anemia was 53.8% (95% CI: 63.3-67.7). Presence of hypoalbuminemia (P = .021), high erythrocyte sedimentation rate (P = .006), and high C-reactive protein (P = .03) was significantly associated with positive findings in endoscopic interventions.
Conclusion: We recommend performing upper gastrointestinal endoscopy and/or colonoscopy in patients with severe anemia associated with gastrointestinal symptoms and using laboratory findings of hypoalbuminemia, high erythrocyte sedimentation rate, and C-reactive protein in order to rule out gastrointestinal pathologies.
