A retrospective single-institution review of the impact of COVID-19 on severity of biliary disease.

BACKGROUND: The COVID-19 pandemic possessed far-reaching health implications beyond the public health impact that have yet to be fully elucidated. We hypothesized that the COVID-19 pandemic led to an increase in biliary disease complexity and incidence of emergency cholecystectomy. METHODS: We reviewed our institutional experience with cholecystectomy from February 2019-February 2021, n = 912. Pre COVID-19 pandemic patients were compared to patients after the onset of the pandemic. Baseline characteristics were compared between groups. A Cochran-Armitage test for trend assessed the temporal impact of COVID-19 on emergency presentation and gallbladder disease complexity. RESULTS: We identified 442 patients pre-pandemic and 470 patients during the pandemic. No significant differences were noted in demographics. COVID-19 significantly impacted emergency presentation (43.2% vs. 56.8%, p= <0.01), cholecystitis (53.2% vs 61.8%; p=<0.01), and gangrenous cholecystitis (2.8% vs 6.1%; p=<0.01). Both groups had similar clinical outcomes. CONCLUSIONS: The COVID-19 pandemic affected an increased incidence of emergency presentation and complexity of gallbladder disease but did not significantly impact clinical outcomes. These findings may have broader implications for other diseases possibly affected by COVID-19.

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.
