摘要Background:Acute suppurative terminal cholangitis (ASTC) is rarer than acute obstructive cholangitis and is not well studied. To explore this subtype of acute cholangitis,we described our clinical experience with ASTC.Methods:We performed a retrospective review of patients with ASTC admitted to our center from September 2014 to August 2020. We analyzed their clinical characteristics,including etiology,clinical manifestations,imaging features,treatment and prognosis. Results:A total of 32 ASTC patients were included in the analysis. The majority of the patients had a history of biliary operations,and clinical manifestations were occult and atypical. The positive rate of bacterial culture was 46.9％. All the patients had typical imaging features on computed tomography and magnetic resonance imaging. Treatment with effective antibiotics was provided as soon as diagnosis was established. After treatment,most patients had a good outcome. Elevated levels of total bilirubin,aspar-tate aminotransferase,procalcitonin and gamma-glutamyltransferase were the characteristics of critically ill patients and were associated with relatively poor prognosis.Conclusions:Our results demonstrated that ASTC should be recognized as a new subtype of acute cholan-gitis,and that earlier diagnosis and more personalized treatments are needed.
