[Acute cholecystitis].

Acute cholecystitis is one of the most frequent complications in gallstone disease. Recently, new diagnosis criteria and severity assessment score have been defined and allow adequate treatment of each category. Early laparoscopic cholecystectomy is the treatment of choice in mild and moderate cholecystitis. In severe cholecystitis primary stabilization of organ failure is recommended as well as urgent cholecystectomy or percutaneous drainage of the gallbladder.
