Author contributions: Gupta N designed and performed the research, performed the statistical analysis, and wrote the paper; Siddiqui U, Waxman I and Chapman C provided clinical advice and contributed to the data set; Koons A and Valuckaite V provided administrative support for VLE system use and patient participation; Xiao SY, Setia N and Hart J performed histologic analysis; Konda V designed the research and supervised the report
Institutional review board statement: This study was reviewed and approved by the IRB committee of the University of Chicago.
Informed consent statement: Patients were not required to give informed consent to the study because the analysis used anonymous clinical data that were obtained after the patient agreed to treatment and VLE imaging by written consent.

Core Tip
Core tip: This is a retrospective study to explore volumetric laser endomicroscopy (VLE) imaging features associated with neoplasia at the gastroesophageal junction (GEJ) and gastric cardia. Histologically abnormal mucosa due to inflammation or neoplasia more often produces abnormal VLE imaging. Specifically, VLE imaging features of irregular surface, heterogeneous scattering and presence of anomalous glands were more often seen in cases of neoplasia than those without. The GEJ and gastric cardia can be difficult to assess endoscopically for dysplasia, and VLE imaging in this area can aid in a “red-flag” biopsy technique.
