Post‐COVID‐19 syndrome mimicking cholangiocarcinoma: A case report.

Key Clinical Message: The differential diagnosis of post‐COVID‐19 syndrome is important in patients with symptoms of biliary obstruction. This patient had severe COVID‐19 who underwent ERCP and mimicked cholangiocarcinoma. Patients with severe coronavirus disease 2019 (COVID‐19) manifest liver injuries with pathological changes because of lowered blood oxygen saturation, cardiac malfunction, hepatotoxic drugs during treatment, and cellular injury. This paper reports a patient with a history of severe COVID‐19 who mimics cholangiocarcinoma after undergoing endoscopic retrograde cholangiopancreatography (ERCP). It was shown that differential diagnosis of post‐COVID‐19 syndrome is greatly important mostly in patients with symptoms of biliary obstruction. [ABSTRACT FROM AUTHOR]
