Endoscopic submucosal dissection of superficial digestive tumors after evaluation through magnification chromoendoscopy and endoscopic ultrasound with miniprobes. Report of three cases.

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.
