Major complication of cholelithiasis (i.e., gallstones); symptomatic gallstones are common before developing cholecystitis.
Patients typically present with pain and localised tenderness, with or without guarding, in the upper right quadrant.
There may be evidence of a systemic inflammatory response with fever, elevated white cell count, and raised C-reactive protein.
Ultrasound is the definitive initial test. Magnetic resonance cholangiopancreatography may be required. In a patient with suspected sepsis, use computed tomography (or magnetic resonance imaging)to identify the cause.
Treatment is withantibiotics, analgesia, and fluid resuscitation as required, likely to be followed by an early cholecystectomy.
Acute cholecystitis is acute gallbladder inflammation, and one of the major complications of cholelithiasis or gallstones. It develops in up to 10% of patients with symptomatic gallstones. In most cases (90%), it is caused by complete cystic duct obstruction usually due to an impacted gallstone in the gallbladder neck or cystic duct, which leads to inflammation within the gallbladder wall. In 5% of cases, bile inspissation (due to dehydration) or bile stasis (due to trauma or severe systemic illness) can block the cystic duct, causing an acalculous cholecystitis.
