Local recurrence of early esophageal carcinoma after endoscopic mucosal resection

We performed endoscopic mucosal resection on 25 patients with early esophageal carcinoma where the depth of invasion was limited to in the lamina propria mucosae (m2) and we observed local recurrent cancer in 2 patients (8%). To reduce the rate of local recurrent cancer, the method of resection was aimed at pathological negative stumps and establishment of a strict standard of judgement on clinically complete resection were considered to be necessary. Furthermore, complete cure was possible even in patients with pathologically positive stumps in cases where no recurrent cancer was observed over a 1 year period following endoscopic mucosal resection.
