title: Hyperplastic polyps of the gastric antrum in patients with gastrointestinal blood loss.
abstract: The significance of hyperplastic polyps of the gastric antrum in anemic patients with suspected gastrointestinal bleeding has not been determined. The aim of this study is to evaluate the prevalence and prognosis of such polyps in this patient group. Clinical records of patients referred to our endoscopy lab from November 1999 to February 2003 for the evaluation of iron deficiency anemia or suspected gastrointestinal bleeding were reviewed. There were 987 patients. Fourteen patients (1.4%) had hyperplastic polyps in the gastric antrum. Five of the patients reported melena, but the rest were asymptomatic. Multiple antral polyps were present in seven cases. The largest polyp measured 5.0 cm. Helicobacter pylori infection was present in one patient. All patients were anemic and nine had documented iron deficiency. No follow-up information was available in four patients. Hyperplastic polyps of the gastric antrum are a rare but significant cause of gastrointestinal blood loss in older patients. Removal of the polyps using endoscopic or surgical methods may be required for resolution of the blood loss along with iron supplementation. Gastroenterologists should be aware that hyperplastic polyps of the gastric antrum might result in gastrointestinal blood loss and iron deficiency anemia.
