Study population: Major patient, hospitalized in a MIR with a diagnosis of CA between 2006 and 2019, whatever the etiology, having had a drainage of the bile ducts regardless of the technique used and the initiation of antibiotic therapy.

Brief summary: Acute cholangitis (AC) occurs when biliary stenosis, due to various benign causes (often gallstones) or the presence of a tumour, leads to cholestasis and biliary infection. AC is a life-threatening infection if not diagnosed and treated in time, its mortality ranges from 1.4% to 5.2%. AC can be classified into different stages of severity depending on organ failure. A severity classification has been proposed by the Asian recommendations of Tokyo 2013: Grade I (Benin), Grade II (Moderate) and Grade III (Severe).

AC treatment includes endoscopic or percutaneous bile drainage in combination with systemic antibiotic treatment. It is currently recommended that patients with severe CA (Grade III) have biliary drainage within 24 hours, although it has not been shown to improve their survival. The emergence of antibiotic-resistant germs, which is a public health issue, calls for reasonable and considered use of antibiotics. Reducing the duration of antibiotic therapy is a fundamental measure of antimicrobial management and antibiotics sparing. 7 to 10 days of antibiotic treatment is common in the treatment of CA. A 14-day treatment is recommended in case of associated bacteremia. A recent study of 263 patients showed that reducing the duration of antibiotic therapy to less than 7 days in patients with CA associated with bacteremia with effective drainage does not increase the risk of recurrence or mortality at 30 days. However, this study was monocentric retrospective and compared groups that were unbalanced in terms of CA severity. The optimal duration of antibiotic therapy in the treatment of CA in critically ill patients hospitalized in intensive care remains poorly known.

The main purpose of this study is to compare short antibiotic therapy with long antibiotic therapy in terms of mortality in patients with AC admitted in intensive care unit (ICU).

Detailed description: Using electronic patient data monitoring systems, the investigators reviewed all patients with a diagnosis of AC admitted to digestive liver disease unity or ICUs at the Nantes University Hospital, Rennes University Hospital from January 1, 2006, to december 31, 2018. For enrolled patients, general clinical characteristics were collected. Patients were categorized into two groups according to antibiotics duration, and the differences of these characteristics between two groups were evaluated.
