Cholecystitis is an inflammation of the gallbladder wall; it may be either acute or chronic. It is almost always associated with cholelithiasis, or gallstones, which lodge in the gallbladder, cystic duct, or common bile duct. Silent gallstones are so common that most of the American public may have them at some time; only stones that are symptomatic require treatment. In developed countries, the prevalence is 10% to 20%, and in the United States, approximately 20 million people have gallstones.
Gallstones are most commonly made of either cholesterol or bilirubin and calcium. If gallstones obstruct the neck of the gallbladder or the cystic duct, the gallbladder can become infected with bacteria such as Escherichia coli. The primary agents, however, are not the bacteria but mediators such as members of the prostaglandin family. The gallbladder becomes enlarged up to two to three times normal, thus decreasing tissue perfusion. If the gallbladder becomes ischemic as well as infected, necrosis, perforation, and sepsis can follow.
