Who is at risk for acalculous cholecystitis?
Acalculous cholecystitis oc- curs in the absence of cholelithiasis in chronically debilitated patients, those on TPN, and trauma or burn victims.
Presentation of acute cholecystitis?
RUQ pain, nausea, low-grade fever, and vomiting. More severe/longer than biliary colic.
Physical exam signs of acute cholecystitis?
RUQ tenderness, inspiratory arrest during deep palpation of the RUQ (Murphy’s sign), low-grade fever, leukocytosis, mild icterus, and possibly guarding or rebound tenderness may be present on examination.
