Acute Cholecystitis

Diagnosis

  1. RUQ pain + fever + leukocytosis associated with gallbladder inflammation
  2. Ultrasound
    1. GB wall thickening (greater than 4-5mm) or edema (double wall sign)
    2. Sonographic Murphy's Sign

Treatment

  1. Antibiotics
    1. Although clear evidence is lacking, assoc/ w/ decreased wnd infection and bacteremia
    2. CTX + metronidazole OR piperacillin/tazobactam (Zosyn) OR ampicillin-sulbactam (Unasyn)
  2. Admit

Complications

  1. Gangrene
    1. Occurs in 20% if untreated (esp. diabetics, elderly, delay in seeking care)
    2. Consider if pt presents with sepsis in addition to cholecystitis
