Cefazolin/therapeutic use; Child, Preschool; Cholecystitis/diagnosis Sonogram (often sequential) and hepatic iminodiacetic acid scans are the most reliable modalities for diagnosis. It is generally agreed that cholecystectomy is the definitive therapy for AAC. However, at times a diagnostic/therapeutic drainage via interventional radiology/surgery may be necessary and life-saving, and may be the only treatment needed
13.2 Acute Cholecystitis. Acute calculous cholecystitis carries a low risk of mortality in patients younger than 80 years, approximately 0.5%; however, the mortality risk can be as high as 11.6% in patients older than 80 years. 2 The pathogenesis involves a gallstone or biliary sludge obstructing the cystic duct, resulting in increased intraluminal pressure. This pressure, in combination with cholesterol supersaturated bile, triggers an inflammatory response Acute cholecystitis (AC) is severe inflammation of the gallbladder (GB) with intense abdominal pain dominating the clinical presentation. AC is divided into acute calculous cholecystitis (ACC) and acute acalculous cholecystitis (AAC). ACC represents over 90% of all AC cases, 1 initiated by a sentinel event of an obstructing gallstone in the. Because of the low positive predictive value, CT findings suggestive of acute cholecystitis should be interpreted with caution and should probably serve as justification for further investigation with abdominal ultrasound. CT has a relatively high negative predictive value (89%), and acute cholecystitis is unlikely in the setting of a negative CT

Acute cholecystitis (AC) occurs as a result of inflammation of the gallbladder (GB) wall, usually because of obstruction of the cystic duct (see the image below). In 90% of cases, AC is initiated by the impaction of a calculus in the neck of the GB or in the cystic duct.  Cholelithiasis affects approximately 20 million people in the United States each year, with 20% of symptomatic patients.

Definition: Acute inflammation of the gallbladder Variant Forms. Acalculous cholecystitis (10% of cases): Inflammation of the gallbladder in the absence of gallstones or cystic duct obstruction that is more common in older patients and after non-biliary tract surgery; Emphysematous cholecystitis (1% of cases): Inflammation of the gallbladder along with the presence of gas in the gallbladder wall Objective To evaluate acute acalculous cholecystitis (AAC) as a potential safety risk for patients treated with alemtuzumab.

Acalculous cholecystitis. Acalculous cholecystitis is a confusing entity. True acalculous, non-obstructive cholecystitis is extremely rare and is the result of primary ischemic necrosis of the gallbladder due to an episode of low-flow state, comparable with non-obstructive mesenteric ischemia (NOMI) leading to small bowel infarction Although recognized for more than 150 years, acute acalculous cholecystitis (AAC) remains an elusive diagnosis. This is likely because of the complex clinical setting in which this entity develops, the lack of large prospective controlled trials that evaluate various diagnostic modalities, and thus dependence on a small data base for clinical decision making Acute acalculous cholecystitis (AAC) diagnosed usually by US finding of thick gallbladder wall and free fluid around it without gallstones . Its relatively rare in paediatrics and can be classified into three categories: (1) Related to critical medical conditions, like sepsis, post-surgery, and prolonged total parenteral nutrition
