Liver cirrhosis is a risk factor for poor prognosis of acute cholangitis caused by choledocholithiasis.

INTRODUCTION AND OBJECTIVES: Acute cholangitis, which is characterized by biliary infection and acute liver injury, may impact cirrhosis prognosis. However, the prognosis itself remains unclear. MATERIALS AND METHODS: This multicenter retrospective cohort study compared the mortality and liver function change between patients with and without cirrhosis who underwent endoscopic treatment for acute cholangitis caused by choledocholithiasis between January 2004 and December 2019. RESULTS: We analyzed 699 patients, 44 of whom had cirrhosis. The cirrhotic group had a significantly higher 30-day mortality rate than the noncirrhotic group (14% vs. 1%; P < 0.001). The cirrhotic group also had significantly lower total bilirubin and albumin recovery. However, all patients with cirrhosis who survived achieved total-bilirubin recovery, and 91% achieved albumin recovery within 90 days. In multivariable Cox regression analysis, the independent risk factors for total-bilirubin recovery included cirrhosis (hazard ratio, 0.37; 95%CI, 0.24‒0.58; P < 0.001) and high total-bilirubin level (0.46; 95%CI, 0.34‒0.60; P < 0.001), whereas those for albumin recovery were cirrhosis (0.51; 95%CI, 0.33‒0.79; P = 0.002), high age (0.62; 95%CI, 0.47‒0.82; P < 0.001), organ dysfunction (0.62; 95%CI, 0.39‒0.96; P = 0.03), low albumin level (0.57; 95%CI, 0.36‒0.91; P = 0.02), and high C-reactive protein level (0.73; 95%CI, 0.56‒0.95; P = 0.02). CONCLUSIONS: Patients with cirrhosis complicated with acute cholangitis had poor prognosis. Recovery of liver function after endoscopic treatment was slow; nevertheless, most patients who survived could recover within 90 days.
