“…Volumetric laser endomicroscopy (VLE) is an advanced imaging method that applies the principles of optical coherence tomography. 32 In an observational study conducted by Smith et al, 33 VLE-guided biopsy improved, compared to random biopsies, the detection of BERN by 700% in cases where with other imaging methods no visual cues for neoplasia had been detected. However, the application of VLE and the interpretation of acquired information require practice and experience.…”

Barrett’s esophagus is associated with an increased risk of adenocarcinoma. Thorough screening during endoscopic surveillance is crucial to improve patient prognosis. Detecting and characterizing dysplastic or neoplastic Barrett’s esophagus during routine endoscopy are challenging, even for expert endoscopists. Artificial intelligence-based clinical decision support systems have been developed to provide additional assistance to physicians performing diagnostic and therapeutic gastrointestinal endoscopy. In this article, we review the current role of artificial intelligence in the management of Barrett’s esophagus and elaborate on potential artificial intelligence in the future.

“…VLE uses a laser probe within a balloon catheter to circumferentially evaluate a 6 cm segment of the esophagus to a depth of 3 mm and a resolution of 7 to 10 μm. 35 It allows for two-dimensional cross-sectional images of all four layers of the esophagus at 10 times the resolution of an endoscopic ultrasound. At 7 to 10 μm, it can visualize glands, crypts, and villi, but not cellular features.…”

“…Additionally, VLE alone may be limited by cost, commercial availability, lack of standardized protocol for image interpretation, and the need for additional training to develop competency in VLE interpretation (Table 1). 35,42,43 However, recent advancements in VLE technology such as CAD, IRIS, and laser marking have shown promising results and may offer a diagnostic benefit for detection of BE-related dysplasia in the future.…”

Barrett’s esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC), and is caused by chronic gastroesophageal reflux. BE can progress over time from metaplasia to dysplasia, and eventually to EAC. EAC is associated with a poor prognosis, often due to advanced disease at the time of diagnosis. However, if BE is diagnosed early, pharmacologic and endoscopic treatments can prevent progression to EAC. The current standard of care for BE surveillance utilizes the Seattle protocol. Unfortunately, a sizable proportion of early EAC and BE-related high-grade dysplasia (HGD) are missed due to poor adherence to the Seattle protocol and sampling errors. New modalities using artificial intelligence (AI) have been proposed to improve the detection of early EAC and BE-related HGD. This review will focus on AI technology and its application to various endoscopic modalities such as high-definition white light endoscopy, narrow-band imaging, and volumetric laser endomicroscopy.
