Abstract

BACKGROUND/AIMS
Endoscopic mucosal resection (EMR) has been known as a method of local treatment for early gastric cancer (EGC) or gastric adenoma. It has been widely accepted as a useful method due to its minimal invasiveness, safety and satisfactory result. The purpose of this study was to identify the factors affecting the recurrence after EMR.
METHODS
Three hundred twenty adenomas in 297 patients were treated by EMR from January, 1991 until July 2003. Among those, 197 lesions in 184 patients that could have been followed-up were analyzed retrospectively.
RESULTS
The mean follow-up period was 15.0 (1~89) months. Of the 197 lesions, there were 35 recurrences (17.7%). The recurrence rate was higher in lesions associated with severe mucosal atrophy and intestinal metaplasia in surrounding mucosa (p=0.035). Other factors showed no statistically significant difference in recurrence rate.
CONCLUSIONS
In this study, we concluded that the presence of intestinal metaplasia and severe atrophic background mucosa were related to the recurrence of gastric adenoma after EMR.
