Ambe et al developed a score for evaluating a patient with acute cholecystitis prior to cholecystectomy. The authors are from Helios Klinikum Wuppertal and Witten/Herdecke University.
Patient selection: acute cholecystitis prior to surgery
Parameters:
(1) gender
(2) age in years
(3) body mass index (BMI)
(4) ASA score
(5) recurrent colics (biliary)
(6) gallbladder wall thickness in mm
(7) WBC count per microliter
(8) C reactive protein (CRP) in mg/dL

where:
• The first 4 items are referred to as patient-dependent parameters.
• The next 4 items are referred to as clinical parameters.
total score =
= SUM(points for all 8 parameters)
Interpretation:
• minimum score: 0
• maximum score: 9
• The higher the score the longer the operative time, the greater the need for intensive care and the longer the hospital stay.
