ABSTRACT
The occurrence of postoperative pancreatic fistula following laparoscopic pancreaticoduodenectomy (LPD) is a significant concern, yet there is currently a lack of consensus on reliable predictive methods for this complication. Therefore, the aim of this study was to assess the clinical significance of C-reactive protein (CRP) and procalcitonin (PCT) values and their reliability in early predicting the development of clinically relevant pancreatic fistula (CRPF) following LPD.A retrospective analysis was conducted using data from 120 patients who had LPD between September 2019 and December 2021. Preoperative assessment data, standard patients' demographic and clinicopathological characteristics, intra- and postoperative evaluation, as well as postoperative laboratory values on postoperative days (PODs) 1, 3, and 7, including white blood cells (WBCs), CRP, and PCT, were prospectively recorded on a dedicated database. Two clinicians separately collected and cross-checked all of the data.Among 120 patients [77 men (64%), 43 women (36%], CRPF occurred in 15 patients (11 grade B and 4 grade C fistulas). The incidence rate of CRPF was 12.3%. A comparison of the median values of WBCs, PCT, and CRP across the two groups revealed that the CRPF group had higher values on most PODs than the non-CRPF group. Receiver operating characteristic (ROC) analysis was used to calculate the area under the curve (AUC) and cutoff values. It was discovered that POD 3 has the most accurate and significant values for WBCs, CRP, and PCT. According to the ROC plots, the AUC for WBCs was 0.842, whereas the AUC for PCT was 0.909. As for CRP, the AUC was 0.941 (95% CI 0.899-0.983, p < 0.01) with a cutoff value of 203.45, indicating a sensitivity of 93.3% and specificity of 91.4%.Both CRP and PCT can be used to predict the early onset of CRPF following LPD, with CRP being slightly superior on POD 3.
