Same day barium esophagography and high-resolution manometry during the COVID-19 pandemic

Purpose: Double contrast barium esophagography (BAS) and high-resolution manometry (HRM) are traditionally performed on separate days to allow for pre-procedural fasting. In an effort to minimize COVID-19 exposure and improve appointment efficiency with required pre-procedure testing, we permitted same day HRM prior to BAS. Our study aimed to evaluate the adequacy of barium mucosal coating with same day HRM prior to BAS compared to BAS alone.

Methods: We performed a retrospective pilot cohort study including 14 patients undergoing same day HRM prior to BAS and 20 patients undergoing BAS alone over an 8-month interval during the COVID-19 pandemic. Three abdominal imaging subspecialty-trained radiologists blindly reviewed the images and graded adequacy of esophageal coating on a 4-point scale with a score of 1 representing inadequate coating and 4 representing optimal coating.

Results: For the cohort studied thus far, the mean grade of the HRM and BAS group was 3.17 with a standard deviation of 0.66. The mean grade of the BAS alone group was 3.13 with a standard deviation of 0.79. There was no statistical difference in the adequacy of esophageal coating between the two groups (p-value 0.97).

Conclusion: Same day HRM prior to BAS has no detrimental effect on barium mucosal coating compared to BAS alone. Though created to limit patient exposures during the COVID pandemic, same day BAS and HRM may prevent delays in care and improve convenience towards improved patient-centered care beyond the pandemic.
