Post-coronavirus disease 2019 (COVID-19) cholangiopathy is a destructive bile duct condition often seen in critically ill patients. Endoscopic retrograde cholangiopancreatography (ERCP) aids diagnosis and management, with interventions improving cholestasis markers.
Area of Science:
- Gastroenterology and Hepatology
- Infectious Diseases
- Critical Care Medicine
Background:
- Post-coronavirus disease 2019 (COVID-19) cholangiopathy is a serious gastrointestinal complication.
- Endoscopic features of this condition are not well-defined.
Purpose of the Study:
- To define the endoscopic features of post-COVID-19 cholangiopathy.
- To clarify the role of endoscopic retrograde cholangiopancreatography (ERCP) in managing this condition.
Main Methods:
- Observational study of 46 patients with confirmed post-COVID-19 cholangiopathy.
- Analysis of 141 ERCP procedures to identify endoscopic and cholangiographic features.
Main Results:
- Post-COVID-19 cholangiopathy presents as a destructive variant of secondary sclerosing cholangitis, appearing early in critical care.
- Typical features include centripetal intrahepatic bile duct destruction, vanishing bile ducts, and biliary casts (85%).
- Complications include liver abscesses; prognosis is poor with a 1-year transplant-free survival of 44%.
Conclusions:
- ERCP is crucial for diagnosing, prognosing, and managing post-COVID-19 cholangiopathy.
- Interventional endoscopy with cast removal can improve cholestasis parameters.
