Endoscopy is indicated for the evaluation of unexplained iron deficiency to rule out neoplasia. Iron deficiency is common in postgastrectomy patients. The endoscopic yield for significant pathology in these patients is unknown but is expected to be lower than for other iron-deficient groups. A retrospective case-control study with 2:1 matching was performed comparing iron-deficient patients (ferritin ≤50 μg/liter) having prior Billroth I or Billroth II gastrectomy to matched iron-deficient controls with normal gastric anatomy. There were 52 postgastrectomy patients and 113 controls. There were no significant differences between postgastrectomy patient and controls in age, gender ratio, or laboratory test results, with the exception of MCV (88.9 ± -1.1 vs 86.0 ± -0.8, mean ± SEM, P = 0.048) There were no significant differences in the prevalence of upper gastrointestinal pathology (24.5% vs 29.2%), large (>1 cm) colon polyps (8.3% vs 5.2%), or the presence of any adenomatous colon polyp (28.6% vs 18.9%). There were no malignancies. In conclusion, prevalence of clinically significant pathology is similar for postgastrectomy and nonpostgastrectomy iron-deficient patients. Endoscopic evaluation of iron deficiency should not differ in postgastrectomy patients.
