Overview
Common risk factors in the development of cholangitis are gallstones, sclerosing cholangitis, and HIV. Variations in treatment and risk factors influence mortality rates in patients with cholangitis, and these rates indicate the necessity for standardized diagnostic, treatment, and severity assessment criteria.
Risk Factors
- Advanced age (greater than 70 years of age), neurologic disease, and periampullary diverticula are risk factors for development of cholangitis in patients with biliary stones.[1]
- The bile of healthy individuals is generally aseptic.[2]
- Bile culture is positive for microorganisms in:
- 16% of patients undergoing a non-biliary operation
- 72% of acute cholangitis patients
- 44% of chronic cholangitis patients
- 50% of patients with biliary obstruction.
- Bile culture is positive for microorganisms in:
- The bacteria in bile are identified in 90% of patients with choledocholithiasis, accompanied by jaundice.
- Patients with incomplete obstruction of the bile duct present with a higher positive bile culture rate than those with complete obstruction of the bile duct.[2]
Other common risk factors for cholangitis include:
- Previous history of gallstones
- A history of sclerosing cholangitis
- HIV
- Narrowing of the common bile duct due to cancer
- Traveling to countries where you might catch a worm or parasite infection
- Presence of liver abscess
- Acute renal failure
