Successful en bloc endoscopic submucosal dissection of early gastric cancer and rectal lateral spreading tumor in a Greek hospital

Basioukas S. and Xinopoulos D. [1] previously reported successful endoscopic submucosal dissection (ESD) of early gastric cancer, type ‘0-IIa’, in a Greek hospital. We would also like to add our experience from gastric and rectal ESD and one-year follow up. Although, narrow band imaging (NBI) magnification endoscopy is a prerequisite, for detailed evaluation of NBI magnifying patterns of mucosal cancer, according to Japanese experts [2], we managed to successfully complete two ESD cases, despite the absence of NBI magnification endoscopy, as was also the case in Basioukas’ and Xinopoulos’ [1] report. Furthermore, we report sufficient follow up in our cases (no local recurrence at one year), necessary for curable ESD.
