[Gallstones - Causes and Consequences].

Gallstones and their complications are one of most frequent gastroenterological diseases leading to hospital admission in Europe. Cholesterol stones are the most common; except of few patients there is a direct link to lifestyle. Obesity, diabetes and insufficient physical activity represent the major risk factors. Abdominal ultrasound is the gold standard for detection of gallstones. ERCP is indicated only in the therapeutic setting. In case of symptomatic gallbladder stones as well as bile duct stones, cholecystectomy is necessary. Higher age is no contraindication. To avoid further biliary colic episodes and / or additional complications, cholecystectomy should be performed as early as possible. In case of acute cholecystitis, cholecystectomy should be performed within 24 h after admission.
