BACKGROUND: This study attempted to determine the indication for endoscopic mucosal resection with a ligating device (EMRL) and to assess the efficacy of radical (complete) resection of early gastric carcinoma and adenoma.
METHODS: Sixteen patients with early gastric carcinoma (17 lesions) and 21 patients with gastric adenoma (23 lesions) underwent EMRL with an endoscope with a ligating device. After epinephrine solution was injected into the submucosa, the lesions were aspirated, ligated, and resected.
RESULTS: Twelve of 17 early carcinomas (70.6%) and 18 of 23 adenomas (78.3%) were radically resected by EMRL. The average size of the resected specimens was 12.8 x 11.0 mm. The rate of successful radical resection by EMRL, including piecemeal resection, was 100% (15/15) for lesions located in the antrum, 80% (4/5) in the angle, 61.1% (11/18) in the body, and 0% (0/2) for lesions at the cardia. Repeat EMRL was performed successfully in cases of partial resection (n = 3). No serious complication was encountered. No recurrence of the tumors was identified in cases of radical resection during a median follow-up period of 22.8 months.
CONCLUSION: EMRL is suitable for the treatment of gastric tumorous lesions. For the treatment of early carcinoma, well-differentiated mucosal carcinomas smaller than 10 mm located in the distal stomach represent the best indication for EMRL.
