Background/aims: The aim of this study was to evaluate the prevalence of colorectal neoplasia in subjects with fundic gland polyps (FGPs) and the relationship between FGPs and colorectal neoplasia in Korea.
Methods: We analyzed 128 consecutive patients with FPGs who underwent colonoscopy between January 2009 and December 2013. For each case, age- (±5 years) and sex-matched controls were identified from among patients with hyperplastic polyps, gastric neoplasms, and healthy controls. Clinical characteristics were reviewed from medical records, colonoscopic findings, pathologic findings, and computed tomography images. The outcome was evaluated by comparison of advanced colonic neoplasia detection rates.
Results: Of the 128 patients, seven (5.1%) had colon cancers and seven (5.1%) had advanced adenomas. A case-control study revealed that the odds of detecting a colorectal cancer was 3.8 times greater in patients with FGPs than in the age- and sex-matched healthy controls (odds ratio [OR], 3.80; 95% confidence interval [CI], 1.09-13.24; P =0.04) and 4.1 times greater in patients with FGPs than in healthy controls over 50 years of age (OR, 4.10; 95% CI, 1.16-14.45; P =0.04). Among patients with FGPs over 50 years old, male sex (OR, 4.83; 95% CI, 1.23-18.94; P =0.02), and age (OR, 9.90; 95% CI, 1.21-81.08; P =0.03) were associated with an increased prevalence of advanced colorectal neoplasms.
Conclusions: The yield of colonoscopy in colorectal cancer patients with FGPs was substantially higher than that in average-risk subjects. Colonoscopy verification is warranted in patients with FGPs, especially in those 50 years of age or older.

Article Synopsis
- In familial adenomatous polyposis (FAP) patients, fundic gland polyps (FGPs) are thought to increase the risk of gastric neoplasms, and this study explored how the distribution of these polyps relates to cancer development.
- A review of 195 FAP patients showed that those with a wider distribution of FGPs (classified from P0 to P4) had a higher likelihood of developing gastric neoplasms, particularly in those who were Helicobacter pylori-negative.
- The study concluded that the pattern of FGP distribution is significantly linked to gastric neoplasm risk in FAP patients, with the most severe distribution (P4) indicating the highest risk.

Background And Aim: Gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) is an autosomal dominant syndrome characterized by fundic gland polyps (FGP) as well as an increased risk of gastric cancer. The syndrome has been recognized as a clinical entity for less than a decade. A clinical suspicion may be complex and can vary from incidental findings of FGPs at gastroscopy to obstructive symptoms with dyspepsia and vomiting.

Article Synopsis
- The study aimed to estimate the prevalence of gastric polyps associated with long-term proton pump inhibitor (PPI) use, identify risk factors for their development, and describe the characteristics of these polyps.
- A prospective study involving around 1000 patients in Beirut over a year found a 30% prevalence of gastric polyps linked to PPI use, with polyps primarily occurring in women and typically related to PPI duration rather than dosage.
- No evidence of dysplasia was found in the polyps studied, and while the incidence of fundic gland polyps has risen with chronic PPI use, current data does not establish a clear connection to gastric cancer.

National Council on Radiation Protection and Measurements Commentary No. 33 'Recommendations for Stratification of Equipment Use and Radiation Safety Training for Fluoroscopy' defines an evidence-based, radiation risk classification for fluoroscopically guided procedures (FGPs), provides radiation-related recommendations for the types of fluoroscopes suitable for each class of procedure, and indicates the extent and content of training that ought to be provided to different categories of facility staff who might enter a room where fluoroscopy is or may be performed. For FGP, radiation risk is defined by the type and likelihood of radiation hazards that could be incurred by a patient undergoing a FGP.
