Computed tomography scan imaging in diagnosing acute uncomplicated pancreatitis: Usefulness vs cost

Table 2 BISAP score predicts the mortality risk in acute pancreatitis based on the data within the first 24 h

BISAP score for pancreatitis mortality
Blood urea nitrogen > 25 mg/dL	1 point
Impaired mental status (disorientation, lethargy, somnolence, coma, stupor)	1 point
≥ 2 Systemic Inflammatory Response Syndrome (SIRS) Criteria (temperature > 38 °C or < 36 °C, heart rate > 90, respiratory rate > 20 or PaC02 < 32 mmHg, white blood cell count > 120000/mm3 or < 4000/mm3 or > 10% bands)	1 point
Age ≥ 60 years old	1 point
Pleural effusion present on imaging	1 point

Score of 0 has < 1% and scores ≤ 2 have 1.9% mortality risk, respectively. Patients with scores of 2 or less were included in the study cohort.
