    Accurate diagnosis of the dividing line (DL) of gastric tumors is essential for the complete resection of the tumor through endoscopic submucosal dissection (ESD)
    .


    Before ESD, it was controversial to diagnose DL in gastric tumors only through endoscopy


    diagnosis

    Between July 2015 and December 2016, the study included 96 well-differentiated adenocarcinomas and 32 gastric adenomas
    .


    A total of 122 lesions with clear DL on M-BLI were randomly assigned to receive only M-BLI (M-BLI group) or M-BLI and biopsy confirmation (M-BLI-BC group).


     

    The results showed that there were no significant differences between the two groups in terms of gender, median age, skin color, circumference, gross type, diagnosis based on biopsy, and Helicobacter pylori infection
    .


    The diagnostic accuracy of DL in the M-BLI and M-BLI-BC groups were 100 and 95.


    Infect

    In summary, the results of this study show that the diagnostic ability of M-BLI is very good in diagnosing the boundary between gastric adenoma and well-differentiated adenocarcinoma
    .


    For these lesions, DL confirmed by M-BLI does not need to be confirmed by biopsy
