 We studied if endoscopy using acetic acid is practical or not in the diagnosis of the margin demarcation of type 0IIb early gastric cancer. The endoscopic images of 20 cases with type IIb resected by ESD were evaluated. The images were divided into three levels ; ○ : recognizable distinctly △ : recognizable, but not clearly × : unrecognizable. Endoscopic images with acetic acid only were evaluated as ○ : recognizable distinctly, 9 cases(45%) ; recognizable, but not clearly 7 cases(35%)and unrecognizable, 4cases(20%). 0IIb lesions of the 11cases of △ × were sprayed with indigocarmine or viewed by magnifying observation using NBI after spraying acetic acid. The images of 6 of the 11cases became ○recognizable distinctly. The images of 15 cases(75%)of 20 cases with IIb lesions were evaluated as having become recognizable distinctly by using acetic acid or acetic acid plus indigocarmine or magnifying endoscopy using NBI after apraying acetic acid.
