PrognosisGenerally good with treatment[4]

Cholecystitis is inflammation of the gallbladder.[8] Symptoms include right upper abdominal pain, pain in the right shoulder, nausea, vomiting, and occasionally fever.[1] Often gallbladder attacks (biliary colic) precede acute cholecystitis.[1] The pain lasts longer in cholecystitis than in a typical gallbladder attack.[1] Without appropriate treatment, recurrent episodes of cholecystitis are common.[1] Complications of acute cholecystitis include gallstone pancreatitis, common bile duct stones, or inflammation of the common bile duct.[1][8]

More than 90% of the time acute cholecystitis is caused from blockage of the cystic duct by a gallstone.[1] Risk factors for gallstones include birth control pills, pregnancy, a family history of gallstones, obesity, diabetes, liver disease, or rapid weight loss.[4] Occasionally, acute cholecystitis occurs as a result of vasculitis or chemotherapy, or during recovery from major trauma or burns.[9] Cholecystitis is suspected based on symptoms and laboratory testing.[5] Abdominal ultrasound is then typically used to confirm the diagnosis.[5]

Treatment is usually with laparoscopic gallbladder removal, within 24 hours if possible.[7][10] Taking pictures of the bile ducts during the surgery is recommended.[7] The routine use of antibiotics is controversial.[5][11] They are recommended if surgery cannot occur in a timely manner or if the case is complicated.[5] Stones in the common bile duct can be removed before surgery by endoscopic retrograde cholangiopancreatography (ERCP) or during surgery.[7] Complications from surgery are rare.[4] In people unable to have surgery, gallbladder drainage may be tried.[5]

About 10–15% of adults in the developed world have gallstones.[5] Women more commonly have stones than men and they occur more commonly after age 40.[4] Certain ethnic groups are more often affected; for example, 48% of American Indians have gallstones.[4] Of all people with stones, 1–4% have biliary colic each year.[5] If untreated, about 20% of people with biliary colic develop acute cholecystitis.[5] Once the gallbladder is removed outcomes are generally good.[4] Without treatment, chronic cholecystitis may occur.[2] The word is from Greek, cholecyst- meaning "gallbladder" and -itis meaning "inflammation".[12]
