Q which of the statements regarding gastric polyps is incorrect..
a) Most common gastric polyps are hyperplastic.
b) 20% of all polyps are adenomtaous polyps
c) Endoscopic polypectomy is done for polyps which do not contain invasive cancer
d) Hyperplastic polps can harbour cancer in 2% cases.
Answer
b)
Hyperplastic polyps are the most common polyps in the stomach. They form 25-75% of all gastric polyps. Chronic Atrophic gastritis mostly are responsible for these hyperplastic polyps. They by themselves are non neoplastic but adenocarcinomas have been detected in 2% of cases. Endoscopic polypectomy is the treatment of choice.
Only 10% of all polyps in stomach are adenomatous polyps. They are mostly antral, sessile, solitary and eroded. Adenomatous polyps harbour malignancy 20% of times and endoscopic polypectomy is required in all polyps. Operative excision is required for sessile polyps more than 2cm in size, other polyps found to harbour invasive malignancy and polyps that bleed or are painful.
