Abstract

Background/Aims

The incidental finding of gastrointestinal subepithelial tumors (SETs) is increasing with national cancer screening endoscopy. In a Swedish population, screening endoscopy found a prevalence of SETs of 0.36%. However, the prevalence of gastric SETs in Korean patients has not been described. Therefore, this study evaluated the prevalence of SETs of the stomach in a Korean patient population.

Methods

We reviewed endoscopic reports of 11,712 subjects who underwent screening esophagogastroduodenoscopy (EGD) at Hanyang University Hospital between July 2012 and June 2013.

Results

Among 11,712 patients, 194 (1.7%) had SET of the stomach. Of these, 71 (prevalence, 0.6%) were male and 123 (prevalence, 1.1%) were female. When grouped by age, the prevalence of SET was as follows: 1.0% for patients in their twenties, 6.2% for those in their thirties, 19.1% for those in their forties, 33.0% for those in their fifties, 30.4% for those in their sixties, and 10.3% for those over 70 years of age.

Conclusions

The overall prevalence of gastric SET among healthy examinees was 1.7%. The prevalence of gastric SET increased with age and was higher in female.
