Retrospective evaluation of image-guided cholecystostomy tube utilization and outcomes during the first wave of the COVID-19 pandemic

Abstract

Objectives: During the COVID-19 pandemic, there was a perceived increase in the number of cholecystostomy tube placements. We have retrospectively analyzed the incidence and outcomes of cholecystostomy tube placement during the COVID-19 pandemic surge.Material and Methods: Cholecystostomy tube placement and overall interventional radiology (IR) case volume were analyzed at our tertiary care center during the pandemic (March 15, 2020–July 30, 2020) and compared to the same time period in 2019. In addition, an age- and gender-matched control study of outcomes for 40 patients (25 from our home institution and 15 from our affiliated hospitals) grouped by COVID-19 status who received percutaneous cholecystostomy tubes between March 15, 2020, and July 30, 2020, was performed.Results: We observed a significant increase in relative cholecystostomy tube volume during the pandemic, despite a decrease in total IR case volume. There was no significant difference in pre- or post-procedural laboratory data, vital signs, imaging, or mortality between COVID-positive and COVID-negative patients who received cholecystostomy tubes.Conclusion: Percutaneous cholecystostomy tube placement is likely a safe treatment for acalculous cholecystitis in patients with COVID-19 with equivalent outcomes to patients without COVID-19.
