Endoscopic Submucosal Dissection for Large Colorectal Tumor in a Japanese General Hospital
Figure 1
ESD for a 6.5 cm LST-G of the rectum: 6.5 cm LST-G is observed in the rectum. Initial mucosal incision after submucosal injection at the oral side of the lesion. The body position was changed to allow the lesion to hang by gravity and, thus, to facilitate insertion of the endoscope into the submucosal layer. After the completion of ESD: about a 1/2 circumferential mucosal defect is observed: resected specimen.
