Background/Aims :Endoscopic mucosal resection (EMR) of early gastric cancer (EGC) or gastric flat adenoma has been widely accepted as a useful method due to its minimal invasiveness and satisfactory post- procedure results in maintaining a good quality of life for patients. The purpose is to define the long-term effect and usefulness of EMR of EGC and gastric flat adenoma.
Methods :We analysed, retrospectively, 101 lesions in 96 cases that could be followed-up were analyzed. Endoscopic surveillance with histological examination was carried out every three months for one year after the treatment, every six months for the second year, and annually thereafter.
Results :1) The mean follow-up period was 17.7 months (1∼78). 2)Of the 101 lesions, there were 6 recurrences (5.9%), the mean period was 17.3 months (2∼37). One of 28 EGC, five of 73 gastric flat adenoma showed recurrence. 3) The recurrence rate tended to be higher in as the size increased (p=0.06). In the lesions which were resected by planned piecemeal, 10% of those lesions recurred (4/40), while 3.3% (2/61) of those lesions recurred in which lesions were resected en bloc (p=0.21). 4) With respect to location of the primary lesions, the recurrence rate was higher in the lesions of the cardia (50%, p＜0.05).
Conclusion :We concluded that the size and location of the lesions were related to recurrence after EMR, but sex, pathology, and resection methods were not related.
