Table 1

Criteria for evaluation of acute cholecystitis severity.

Grade 3	Grade 2	Grade 1
Cardiovascular dysfunction: hypotension requiring treatment with dopamine ≥5 μg/kg per min, or any dose of norepinephrine	Elevated WBC count (>18,000/mm^3)	Does not meet criteria of grade 3 and grade 2 acute cholecystitis
Neurological dysfunction: decreased level of consciousness	Palpable tender mass in the right upper abdominal quadrant	Healthy patients with no organ dysfunction and mild inflammatory changes
Respiratory dysfunction: PaO2/FiO2 ratio <300	Duration of complaints >72 h^a
Renal dysfunction: oliguria, creatinine >2.0 mg/dl	Marked local inflammation (gangrenous cholecystitis, pericholecystic abscess, hepatic abscess, biliary peritonitis, emphysematous cholecystitis)
Hepatic dysfunction: PT‐INR > 1.5
Hematological dysfunction: platelet count <100,000/mm^3
