Conditional information

How this model should be used:
This model calculates the risk for postoperative pancreatic fistula (POPF) or severe complications based on preoperative CT images in patients who underwent pancreatoduodenectomy (PD) or pylorus preserving PD (PPPD). To validate these results, a prospective study is required.

Model performance:
The risk score was validated with a 1000-sample bootstrap analysis. These values were comparable to the values of BMI, ASA III, and HU in the multivariate model. No external validation was performed.
