BACKGROUND: Simultaneous pancreas-kidney transplantation (SPK) carries a high risk of major postoperative complications, but knowledge on early warning signs and surrogate markers for postoperative complications is scarce.
AIMS: Our aim was to analyze the complication-predictive value of different laboratory tests in pancreas transplantation.
MATERIALS & METHODS: All SPKs in Finland between January 2010 and February 2020 were retrospectively analyzed. Levels of first three-day plasma amylase, drain fluid amylase, C-reactive protein, C-peptide, plasma trypsinogen, and white blood cell count were assessed for their performance predicting cumulative postoperative complications (assessed using the Comprehensive Complication Index) within 90 days from transplantation by using ROC analyses.
RESULTS: Of the 164 SPK patients included, 39 suffered at least one complication requiring laparotomy. First-day plasma amylase had the best value in predicting complications based on its high AUC value and easy clinical applicability, with an optimum cutoff of six times the upper normal limit. Negative predictive values (NPVs) and positive predictive values of this cutoff were 0.81 and 0.71 for any relaparotomy, and 0.91 and 0.71 for the Comprehensive Complication Index >47.7 (which equals the morbidity of two relaparotomies), respectively.
CONCLUSION: In conclusion, first-day plasma amylase could be able to detect patients at risk of complications after SPK.
