Prognostic Impact of Time to Surgery in Patients With Resectable Pancreatic Ductal Adenocarcinoma.

OBJECTIVES: Some studies suggested the importance of performing pancreatoduodenectomy expeditiously in resectable pancreatic ductal adenocarcinoma (PDAC). This study aimed to assess the prognostic value of time to surgery in patients undergoing pancreatoduodenectomy for PDAC. METHODS: All PDAC patients who underwent upfront pancreatoduodenectomy were collected (2000-2015). Diagnosis date was the computed tomography scan date where a suspicious pancreatic head lesion was observed. Survival analyses were performed using Kaplan-Meier method. Cox model was used to find predictive factors of survival. RESULTS: A total of 192 patients underwent pancreatoduodenectomy. The median time to surgery was 27 days (interquartile range, 17-40 days). The best dichotomous threshold for 24-month overall survival (OS) was 30 days. The median OS was similar between groups with time to surgery of fewer than 30 days and time to surgery of 30 days or more (25 vs 21 months, P = 0.609). Similar results were found for median recurrence-free survivals (19 vs 15 months, P = 0.561). On Cox regressions, time to surgery was not associated with shorter OS. Only lymph node invasion and adjuvant chemotherapy were independent OS predictors (hazard ratio, 2.610, P = 0.006, and hazard ratio, 2.042, P = 0.001). CONCLUSIONS: Delaying surgery 30 days or more after diagnostic computed tomography scan was not associated with poorer OS and recurrence-free survival. Moreover, time to surgery was not prognostic of OS.

Perioperative fluids and complications after pancreatoduodenectomy within an enhanced recovery pathway.

Optimized fluid management is a key component of enhanced recovery (ERAS) pathways. Implementation is challenging for pancreatoduodenectomy (PD) and clear guidance is missing in the respective protocol. The aim of this retrospective study was to evaluate the influence of perioperative intravenous (IV) fluid administration on postoperative complications. 164 consecutive patients undergoing PD within ERAS between October 2012 and June 2017 were included. Perioperative IV fluid and morbidity (Clavien classification and comprehensive complication index (CCI)) were assessed. A threshold of more than 4400 ml IV fluid during the first 24 h could be identified to predict occurrence of complications (area under ROC curve 0.71), with a positive and negative predictive value of 93 and 23% respectively. More than 4400 ml intravenous fluids during the first 24 h was an independent predictor of overall postoperative complications (adjusted odds ratio 4.40, 95% CI 1.47-13.19; p value = 0.008). Patients receiving ≥ 4400 ml were associated with increased overall complications (94 vs 77%; p value < 0.001), especially pulmonary complications (31 vs 16%; p value = 0.037), as well as a higher median CCI (33.7 vs 26.2; p value 0.041). This threshold of 4400 ml intravenous fluid might be a useful indicator for the management following pancreatoduodenectomy.
