Abstract

AIM: To assess the risk of colonic polyps, adenomas and advanced neoplastic lesions (ANL) in patients with sporadic gastric polyps, especially those with fundic gland polyps (FGP).

METHODS: Clinical records of patients who had performed an upper and a lower digestive endoscopy between September 2007 and August 2008 were retrospectively analyzed. A case-control study was carried out, calling patients with gastric polyps as “cases” and patients without gastric polyps as “controls”. The risk of colonic polyps, adenomas and ANL (villous component ≥ 25%, size ≥ 10 mm, or high grade dysplasia) was assessed [odds ratio (OR) and its corresponding 95%CI].

RESULTS: Two hundred and forty seven patients were analyzed: 78 with gastric polyps (cases) and 169 without gastric polyps (controls). Among the cases, the majority of gastric polyps were FGP (80%, CI: 69-88) and hyperplastic (20%, CI: 12-31); 25% had colonic polyps (25% hyperplastic and 68% adenomas, from which 45% were ANL). Among the controls, 20% had colonic polyps (31% hyperplastic and 63% adenomas, from which 41% were ANL). The patients with sporadic FGP had an OR of 1.56 (CI: 0.80-3.04) for colonic polyps, an OR of 1.78 (CI: 0.82-3.84) for colonic adenomas, and an OR of 0.80 (CI: 0.21-2.98) for ANL. Similar results were found in patients with gastric polyps in general.

CONCLUSION: The results of this study did not show more risk of colorectal adenomas or ANL neither in patients with sporadic gastric polyps nor in those with FGP.

Core tip: The risk of colonic adenomas in patients who have sporadic gastric polyps, especially those of fundic gland polyps (FGP), is still to be definitely determined. The purpose of our study was to assess the risk of colonic polyps, adenomas and advanced neoplastic lesions in patients who have sporadic gastric polyps, especially of FGP, due to the fact that these are the most common gastric polyps in our population.
