Abstract
Background/Aims
Laterally spreading tumors (LST) of the colon are defined as tumors over 10 mm in diameter that are low in height and grow superficially. These tumors are highly malignant and usually mucosal lesions, therefore endoscopic mucosal resection is desirable. We analysed retrospectively the result of endoscopic piecemeal mucosal resection (EPMR) in LSTs larger than 20 mm in diameter. Methods: 21 patients with LSTs larger than 20 mm in diameter were treated using EPMR. The resection sites were examined for residual or recurrent lesions by follow-up colonoscopy. Results: Of the 21 patients who underwent EPMR, 2 patients performed surgical resection and 4 patients were lost during follow-up period. Residual or recurrent lesions were detected in 5 of these 15 patients after EPMR. After additional endoscopic therapy, no more residual or recurrent lesions were detected. Conclusions: After EPMR for large LSTs, it is necessary to strictly follow-up at least within 1 year. (Intestinal Research 2003;2:186-191)
