 Thirty-five patients with early-stage gastric cancer who underwent endoscopic submucosal dissection or surgery at our hospital between April 2018 and December 2020 for the presence of “crawling-type” adenocarcinoma of the stomach were enrolled in this study. The patients subsequently underwent preoperative NBI(narrow-band imaging)magnification endoscopy. The endoscopic characteristics of the lesions were investigated and compared with those previously reported.

 In many cases, the lesions lacked color change, elevation, or depression and could only be recognized as disordered gastric subdivisions. On NBI magnification endoscopy, the lesions showed various surface irregularities, and no specific findings were obtained. Irregular micropits were observed in some cases, suggesting that this may be a characteristic finding of “crawling-type” adenocarcinoma of the stomach on NBI magnification endoscopy.
