Background:
Acute cholangitis, also known as ascending cholangitis, is a life-threatening systemic condition that results from a biliary tree infection and obstruction. Severe acute cholangitis was reported to have a mortality rate between 11 and 27% in the 1990s. This article is a literature review about acute cholangitis. Its aim is to review the latest literature about acute cholangitis and to discuss its pathogenesis, clinical presentation, diagnosis, prognosis, risk factors and treatment.
Methods:
Ovid Medline and PubMed database searches were performed for articles about acute cholangitis published in English from 1877 to 2016. The keyword search headings included 'acute', 'ascending' and 'cholangitis', and a combination of these were used. Only articles with full-text descriptions were chosen for this literature review.
Results:
Common causes of biliary tree obstruction include choledocholithiasis, benign and malignant biliary strictures. According to the Tokyo Guidelines, clinical presentation, laboratory blood results and diagnostic imaging are important in the diagnosis of acute cholangitis. Treatments consist of intravenous fluids and antibiotics followed by biliary decompression and drainage. Available drainage options include endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography, endoscopic ultrasound and open surgical drainage.
Conclusion:
It is important to diagnose acute cholangitis as early as possible to initiate appropriate treatments to reduce mortality and morbidity.
