Prediction of severe postoperative complications in pancreatic surgery using the Preoperative Pancreatic Resection (PREPARE) score: a single-center observational study

Aim. To evaluate the effectiveness of the PREPARE score in predicting severe complications after pancreatic surgery.Materials and Methods. The case-control study included patients operated on the pancreas. Grade ≥III Clavien– Dindo complications were designated as “severe”. Patients were divided into two groups: “0–II degree” (control) and “III–V degree” (case). For all patients, scores were calculated, and risk categories were determined according to the PREPARE score.Results. The study included 151 patients: “0–II degree” – 102 (68%) observations, “III–V degree” – 49 (32%). ROC analysis was used for the scores (AUC = 0.616; 95% CI 0.527–0.706; p = 0.014) and for the risk categories (AUC = 0.555; 95% CI 0.463–0.648; p = 0.241) of the PREPARE score.Conclusion. The obtained data do not currently enable us to recommend the PREPARE score for predicting complications of pancreatic surgery.
