title: Hyperplastic gastric polyp causing progressive gastric outlet obstruction.
abstract: Hyperplastic polyps represent 75 to 90% of gastric polypoid lesions. The manifestations of these unique gastric neoplasms vary, including abdominal pain, nausea, and vomiting or gastrointestinal bleeding. The vast majority of these lesions are small, asymptomatic, and found incidentally on radiologic evaluation or endoscopic examination of the upper gastrointestinal tract. Herein we describe a large, benign, pedunculated hyperplastic polyp that led to progressive gastric outlet obstruction. In addition, we provide an overview of gastric polyps and a review of the literature. Excision of gastric polyps by endoscopic or surgical means is recommended as prudent treatment to eliminate occurrence of malignant foci.
