Esophagogastroduodenoscopy was conducted using the LASEREO system (FUJIFILM, Tokyo, Japan) with an EG-L600WR7 or EG-L600ZW7 endoscope. To investigate the efficacy of LCI in increasing the visibility of SNADETs, we prospectively collected one image acquired using white light imaging (WLI), LCI, and blue laser imaging-bright (BLI-bright) at the same site and angle. SNADETs were resected via endoscopy and were pathologically confirmed thereafter. Both endoscopic resection and pathological examination were performed in our institution.

Esophagogastroduodenoscopy was conducted using the LASEREO VP-7000 system with an EG-L600WR7 or EG-L600ZW7 endoscope (FUJIFILM, Tokyo, Japan). The EVIS LUCERA ELITE CV-290 system with a GIF-H260Z or GIF-H290T endoscope (Olympus, Tokyo, Japan) was also used. Moreover, CLE is defined as the area from the squamous-columnar junction (SCJ) to the lower end of the palisade vessels (PVs) when the PVs are recognized or the area from the SCJ to the upper end of the gastric folds when the PVs are not recognized. This study defined CLE ≥ 1 cm as BE with or without intestinal metaplasia. CLE ≥ 3 cm in maximum length was classified as LSBE. CLE < 3 cm was classified as SSBE. The Plague and Paris classifications were used to indicate BE length^{19 (link)} and classify EAC^{20 (link)}, respectively. Reflux esophagitis was evaluated and graded according to the Los Angeles classification (A–D)^{21 (link)}. The degree of atrophic gastritis was evaluated according to the Kimura–Takemoto classification (closed or open type)^{22 (link)}.
