Abstract

Aim: The TBS-derived image processing method, based on the observer's diagnosis, has been developed in the current investigation. Image parametrization is proposed for both novel description and convergent shreds of evidence. Background: Condensed X-ray images of the esophageal timed barium swallow (TBS) provide substantial implications for elucidating the pathophysiological dimensions of esophageal motility disorders. Methods: Through the simultaneous study on TBS and high-resolution manometry (HRM) findings, we performed a retrospective cohort study on 252 patients from March 2018 to October 2019. Interventions, irrelevant information, and insufficient patient data were excluded. Only subjects with adequate data and acceptable test accuracy were considered for participation. We reviewed 117 Dicom (digital imaging and communications in medicine) X-ray images from patients with confirmed diagnoses of achalasia type II, esophagogastric junction outflow obstruction (EGJOO), or non-Achalasia. Results: The results suggested a cut-off level of 47% in DDi (dilated diameter index) as a sign of the dilated body. In achalasia type II patients (n=66 images), the mean DDi was 55.6%. Our method presented a sensitivity of 95% and a specificity of 93% compared to images of the non-Achalasia findings. The mean DDi in EGJOO patients was 50.4%, according to the 27 images. Moreover, results from EGJOO patients provided a sensitivity of 85% and specificity of 87%. Conclusion: TBS is an efficacious method and a prominent component in the process of achalasia diagnosis. Standard parametrization might develop radiological exports proposed by DDi. Our method could assist in obtaining a non-invasive medical diagnosis and help advance diagnostic reports to identify achalasia subtypes somewhat earlier. To the best of our knowledge, this interface is an innovative parametrization for TBS image review. © 2022 Research Institute for Gastroenterology and Liver Diseases. All rights reserved.
