Diagnostic Yield of Upper Gastrointestinal Endoscopy in Patients with Positive Fecal Occult Blood Test
Öz
Background and Aims: The role of upper gastrointestinal endoscopy (UGIE) in patients with a positive fecal occult blood test (FOBT), particularly when colonoscopic findings are normal, remains controversial. This study aimed to assess the diagnostic yield and endoscopic–histopathological findings of UGIE in FOBT-positive patients and to identify clinical factors associated with clinically significant upper gastrointestinal lesions.
Methods: This retrospective study included adult patients (≥18 years) with positive FOBT who underwent both colonoscopy and UGIE between January 2018 and December 2024 at a tertiary care center. Data on demographics, laboratory parameters, medication use, endoscopic findings, and histopathology were collected. Clinically significant lesions were defined as peptic ulcers, erosive esophagitis ≥LA grade B, stigmata of bleeding, neoplasia, or high-grade dysplasia, in accordance with international endoscopy guidelines and prior large observational studies. Predictors of significant lesions were analyzed using multivariable logistic regression with LASSO selection.
Results: A total of 642 patients (mean age 61.4 ± 13.7 years; 54.8% male) were included. Clinically significant upper gastrointestinal lesions were identified in 138 patients (21.5%). The most frequent significant findings were gastric ulcers (61 patients, 9.5%), duodenal ulcers (30 patients, 4.7%), and erosive esophagitis ≥ LA grade B (25 patients, 3.9%). Iron deficiency anemia (adjusted OR 2.11; 95% CI 1.33–3.35) and NSAID and/or anticoagulant use (OR 1.78; 95% CI 1.09–2.94) were independently associated with clinically significant lesions.
Conclusion: Routine UGIE in all FOBT-positive individuals may not be justified; a selective strategy based on risk factors appears more efficient and clinically sound.
