 EMR/EPMR(endoscopic mucosal resection/endoscopic piecemeal mucosal resection)is not just a matter of endoscopic technique but should be well understood as including a whole process from endoscopic prediction of histology before treatment to pathological evaluation of the specimen after resection. Such lesions as predicted to be massively invading the submucosal layer should not be resected endoscopically but should be treated surgically, associated with nodal dissection. Careful observation is important for the prediction of cancer depth and pit pattern or vascular pattern analysis with magnification is very useful for that purpose. The tissue slice of the deepest part of the cancer is necessary for an accurate pathological diagnosis. In order to obtain such a slice, it is important to spread and pin the resected specimen and to cut it under stereomicroscopic observation.
