Dear Editor,
We read with great interest the article by Bodea et al., entitled "Evaluation of P-POSSUM Risk Scoring System in Prediction of Morbidity and Mortality after Pancreaticoduodenectomy" (1). The authors should be congratulated for evaluating perioperative risk prediction in pancreaticoduodenectomy, where accurate estimation of postoperative outcomes remains of considerable clinical importance.
Hwever, we would like to seek clarification regarding the methodology used to estimate postoperative morbidity.
The authors state that physiological scores, operative severity scores, and the predicted risks of complications and death were calculated using the online calculator available at http://www.riskprediction.org.uk/index-pp.php. Subsequently, the manuscript reports predicted morbidity, observed-to-estimated morbidity ratios (O Morb/E Morb), receiver operating characteristic (ROC) analyses for morbidity, and discusses the predictive performance of P-POSSUM for postoperative morbidity throughout the Results and Discussion sections.[read more]
