The efficacy of endoscopic mucosal resection in the diagnosis and treatment of group III gastric lesions

BACKGROUND: The efficacy of endoscopic mucosal resection (EMR) in diagnosing and treating group III lesions was analyzed. PATIENTS AND METHODS: Forty-three patients, with group III lesions confirmed by histopathological examination of the biopsy specimens, were included. All of these patients underwent EMR. The final diagnosis after EMR broadly classified the lesions as adenocarcinoma or adenoma. The clinicopathological features and therapeutic results were analyzed. RESULTS: Adenocarcinoma was identified in 16 patients (37.2%) and adenoma in 27 patients (62.8%). There were no differences in gender, age, lesion site, macroscopic type, or maximum diameter between the two groups. A significant difference in the maximum diameter of elevated lesions (p<0.05) was found between adenocarcinomas and adenomas, with the elevated lesions of adenocarcinomas measuring more than 10 mm. No residual focus recurrence was found among the adenomas. CONCLUSION: We conclude that EMR is effective and useful in diagnosing and treating group III lesions.
