Klompmaker et al reported a risk score for a patient undergoing a distal pancreatectomy with celiac axis resection (DP-CAR). The authors are from multiple institutions in Europe and the United States.
Patient selection: distal pancreatectomy with celiac axis resection
Outcome: 90-day mortality
Parameters:
(1) age in years from 40 to 90 years
(2) sex
(3) ASA status from 1 to 4
(4) body mass index (BMI) in kg per square meter from 20 to 50
(5) multi-visceral resection (other than celiac axis, gallbladder, pancreas or spleen)
(6) open surgery
(7) high volume DP-CAR center (annual volume >=1 procedure per year)
