Overview
Epidemiology and Demographics
Prevalence
- Within a span of ten years, 15–26% of people will suffer one or more episodes of biliary colic, abdominal pain due to the passage of gallstones through the bile duct into the digestive tract.[1]
- 2–3% of people will develop complications of obstruction in the form of acute cholangitis.
- The prevalence of gallstone diseases increase with age and body mass index, a mark of obesity.
- The risk is also increased in those who lose weight rapidly (after weight loss surgery, for example) due to alterations in the composition of the bile that makes it prone to form stones.
Age
- The condition mostly occurs in adults, with a reported median age at onset of 50-60 years.[1]
Gender
- Gallstones are slightly more common in women than in men, and pregnancy increases the risk further.[1]
Race
The prevalence of cholangitis does not vary by race.
Developed Countries
- In Western countries, about 15% of all people have gallstones in their gallbladder, but the majority are unaware of this and have no symptoms.[1]
Underdeveloped Countries
- Parasites, specifically including the species Ascaris, Opisthorchis, Clonorchis, Fasciola and Echinococcus, are commonly associated with cholangitis outside of the United States.[2]
- Ascaris is thought to be the etiologic agent of recurrent pyogenic cholangitis (Oriental cholangiohepatitis) found in Hong Kong, Southeast Asia, Columbia, Italy and South Africa.
