BACKGROUND: Endoscopic mucosal resection (EMR) is now widely accepted as a useful treatment method for gastric adenoma and early gastric cancer (EGC) because of its minimal invasiveness and satisfactory post-procedure results. The purpose of this study is to define the follow-up results and usefulness of EMR. METHODS: We analyzed 54 cases from June 2000 through September 2004. Endoscopy with histological examination was carried out every 3 months for 1 year after EMR. RESULTS: The patients consisted of 42 men and 12 women, and the mean age was 60 years old. The histological results were 42 gastric adenoma and 12 EGC cases. There were 9 cases that had the histological diagnosis changes after EMR. Complete resections was performed for 48 cases and the en block resections were 33 of 34 cases (97%) and piecemeal resections were done in 15 of 20 cases (75%). Recurrence was seen in 4 cases (7.1%), and the mean recurrence period was 7 months. There were 3 gastric adenomas of 42 cases (7.1%), one case of EGC of 12 cases (8.3%), one en block resection of 34 cases (2.9%) and three piecemeal resections of 20 cases (15%). CONCLUSIONS: EMR is a safe and useful treatment method for gastric adenoma and EGC. However, EMR has some limitations that EGC may have lymph node metastases or multiple tumors. So, periodic follow-up is very important. As we acquire more clinical experience, EMR may be accepted as the standard treatment method for gastric adenoma and EGC.
