Magnification chromoendoscopy (MCE) and miniprobes are able to select the tumors suitable for curative endoscopic treatment. Endoscopic submucosal dissection (ESD) is a new endoscopic technique that has a higher complete resection rate and a very low recurrence rate. We present three cases of superficial epithelial digestive tumors that were first evaluated with MCE and miniprobes before being treated by ESD. A complete one-fragment resection was performed with no major complications in all cases.
