Measurement of CLE is most accurate for lengths ≥1 cm, and as such, guidelines do not recommend biopsy of an irregular z-line when seen on endoscopy. However, a CLE is often estimated by visual inspection rather than direct measurement, making this characterization imprecise. In this study, we present methodology to standardize the characterization of the SCJ, hypothesizing that the shape of the z-line can be used as a surrogate classifier. We present a computer-generated algorithm capable of automated segmentation and shape complexity quantification of the z-line.</p><p><strong>Methods: </strong>849 images of the z-line were selected and manually segmented. We used the nnUNet framework to train a model to segment the z-line. An additional dataset of 58 videos containing the z-line were obtained from the Mayo Clinic Endoscopy video library. A high-quality image containing the z-line was selected from each video. Ten gastroenterologists (5 esophageal experts) rated each of the 58 video/image pairs containing the z-line as \"regular\" or \"irregular,\" including their degree of confidence. Fleiss kappa statistics was used to determine interobserver variability. The \"ground truth\" classification was determined by the esophageal expert majority vote. A wavelet decomposition model was then used to determine the threshold of irregularity based on the ground truth. Heat maps were generated for each z-line to determine localized areas of complexity.</p><p><strong>Results: </strong>Fair agreement, with a Fleiss' kappa of 0.39, was observed between the 10 endoscopists when rating the z-line as \"regular\" vs \"irregular\" using this dataset.
