Hyperplastic polyps are common gastric lesions, usually small and asymptomatic. This case highlights a large polyp causing gastric outlet obstruction, emphasizing the need for polyp excision to prevent malignancy.

Area of Science:

  • Gastroenterology
  • Pathology

Background:

  • Hyperplastic polyps constitute 75-90% of gastric polypoid lesions.
  • Gastric polyps can manifest with symptoms like abdominal pain, nausea, vomiting, or gastrointestinal bleeding.

Observation:

  • A large, benign, pedunculated hyperplastic polyp was identified.
  • This specific polyp led to progressive gastric outlet obstruction.

Findings:

  • The majority of gastric polyps are small, asymptomatic, and incidentally discovered.
  • Large hyperplastic polyps can cause significant gastrointestinal obstruction.

Implications:

  • Excision of gastric polyps, whether by endoscopic or surgical methods, is recommended.
  • Timely intervention can eliminate potential malignant foci and prevent complications like obstruction.
